Description
Technical field
The present invention relates to a kind of being used for especially is polished into the armor coated method of jewel with facet at least one; Wherein, Jewel is kept by holding device and is provided with the reflecting layer at least partly, and the material that forms protective layer is administered on the reflecting layer with liquid form and sclerosis then at least partly.
Background technology
Jewel is used to jewellery, and also is used to usually decorate every-day object such as clothes, and be arranged in the base material for this reason or base material on.Jewel be arranged in the base material or base material on those zones usually for example through silver-plated, be provided with the reflecting layer through physical vapor deposition (PVD) or wet chemistry method.
In order to protect this reflecting layer to avoid regulation, especially coating protection layer on the zone that is provided with the reflecting layer of jewel usually such as wearing and tearing, corrosion, jewel is additionally uprised expensive thus.This protective layer can be an enamelled coating.If to being provided with those regional japannings in reflecting layer, then need all the other zones of cap jewel, contact with the paint of the protective layer that is formed for the reflecting layer so that prevent these zones at this.In addition, jewel must be kept by holding device in the japanning process.Can stipulate do not have the zone in reflecting layer to embed in the thermoplastic, for example through jewel is sunk in the paraffin plate to this.Can utilize the japanning shower nozzle under the situation in the zone of not considering not have the reflecting layer, to give the jewel japanning subsequently; To paint form ejection from the nozzle of said japanning shower nozzle with big subtended angle with spraying; Wherein, Holding device is also by japanning together, if be arranged on a plurality of jewels in the holding device thus by japanning, then each jewel is connected through the enamelled coating that links up.
The shortcoming of these methods is; When together the holding device of japanning removes jewel from quilt; Jewel must be split out from coherent enamelled coating sclerosis or that become dry at least; Said holding device keeps jewel and utilizes said holding device in the japanning process, to protect the zone that is not provided with the reflecting layer of jewel in the japanning process, the enamelled coating part on the jewel is impaired thus.Enamelled coating is unascertainable at the terminal of jewel edge separately, because the position of enamelled coating " disconnection " is can not confirm in advance and uncontrollable.When similar problem also appears to large-area member japanning, want the zone of japanning to be clung with adhesive tape and after enamelled coating becomes dry, be removed again there.But different with large-area member such as car body component, be serious less than 1 millimeter less jewel sometimes because enamelled coating breaks off the damage brought for diameter, and also possibly damage jewel itself.
Such position forms the starting point of further peeling off the position of the protective layer that constitutes with the enamelled coating form.Especially little jewel is responsive especially in its edge.Because the disconnection at enamelled coating when holding device removes jewel does not always occur on the same position of jewel, so also such situation possibly take place, promptly enamelled coating was partly peeled off from jewel before breaking off.At this, have only the reflecting layer of several micron thick itself to expose or even removed together usually.Also possible thus is that jewel itself is impaired.
This to take off the position that enamelled coating exposes be the preferred initial point of corrosion, changes or corrosion in creep because thin now reflecting layer is inevitable, finally damage reflecting layer or jewel thus.
In addition, owing to force and must split out jewel from holding device, so limited available protective layer material.Thereby the lackering method of stating employing for existing skill so far is only to use frangible paint, because it can relatively easily rupture.For other paint, remove jewel from holding device and also produce the damage more serious than above-mentioned damage.
Summary of the invention
Task of the present invention is, avoids above shortcoming and provides a kind of being used for that protective layer, especially enamelled coating are coated with the method that installs on the local at least jewel that is provided with the reflecting layer, and this method still technology simply and is apace carried out, and does not cause jewel impaired.
This task will solve through a kind of method with characteristic of claim 1.
For according to method of the present invention; The jewel that sets protective layer is kept by holding device; Wherein, should set the situation of protective layer, should the zone except that protective layer can be arranged in the holding device and/or can be capped in case of necessity for the regional area of jewel only.The material that forms protective layer is applied on the jewel with liquid form and sclerosis then.
Holding device can for example be that jewel is bonded to transmission film on it, has the thermoplasticity bearing of the recess that is used for jewel, the screen device of screening jewel etc.Holding device also can be support plate or have support plate that jewel for example is held on this support plate with its desktop (Tafel), need not to be provided with independent fixed mechanism.
Stipulate now according to the present invention; The material that forms protective layer is with the form of drop, be applied on the zone that will set protective layer, especially enamelled coating of jewel by pattern; Wherein, The drop that is applied on the jewel is applied on the jewel along same direction basically, that is to say that different drops has the substantially the same velocity of direction in application.
At this, the material that forms protective layer is administered to liquid form on the desired regions on the jewel outside, and wherein, jewel part at least is provided with the reflecting layer, coating protection layer at least in part on this reflecting layer.In this regulation, protective layer is arranged on the back side in reflecting layer.In other words, the reflecting layer can be used for improving by this way the eye impressions of the jewel that is made up of glass, that is, light is reflected at the back side of jewel and imitates magnificent gloss thus.If people see the front to jewel, then experience being arranged at only very glittering that reflecting layer place on the jewel back side is reflected.Therefore the back side in reflecting layer be the side that deviates from jewel in reflecting layer.The reflecting layer towards the side of jewel under any circumstance all mirror-polishing ground constitute.The material that forms protective layer is applied on the back side in reflecting layer.
Through be in liquid protective layer material with the drop administered; Because the substantially the same direction of motion of drop and extremely accurately and rightly set the liquid material of protective layer can for the zone that should set protective layer, and avoid protective layer material after atomizing, must be coated with installing on the jewel with the large tracts of land of spraying.In spraying, little drop passive movement in air-flow of protective layer material, the holding device of jewel is thus also by japanning together, and this brings in the problems referred to above when holding device removes jewel.In addition, satellite droplet on spray edge, occurs, these satellite droplet are carried out complicacy and mixed and disorderly sometimes motion and are had the component motion that can not confirm fully because of the vortex of spraying.These satellite droplet bump against on the position of non-hope of jewel and possibly add the protective layer that causes on the jewel and are connected with holding device, and this connection must be disconnected to remove jewel and to start described problem and occur.
In this regulation, in order to protect jewel or reflecting layer, protective layer is arranged on the reflecting layer at least partly, produces the reflective back coating thus.The reflecting layer had been arranged on the surf zone of jewel at this before the method that is used to be provided with protective layer according to the present invention., consider traditional reflecting layer known in the prior art or method here, for example silver-plated by vapour deposition or conventional wet chemistry method for reflecting layer and manufacturing approach thereof.
, except a reflecting layer, can also be provided with other functional layer here, this functional layer equally can be through protecting according to protective layer of the present invention.At this, it can be layer and/or different layer as a decorative layer and the characteristic layers of a plurality of part of the partially absorbing property between reflecting layer and jewel substrate surface.Can expect that also one or more increasing attaches layer between functional layer and/or as uppermost functional layer, attaches coating protection layer on the layer increasing subsequently.Reflecting layer itself can be coated with albedoes different in visible range and be installed on the jewel, if this is to hope.These functional layers can have the zone of hacking, the zone of these hackings be convenient to jewel lay and/or be bonded in the base material subsequently or base material on.The decorative layer of institute's application can be a color layer at this, this color layer for example explicit identification, be used for jewel discern again and be arranged under the reflecting layer or on the zone that is at the outer surface in reflecting layer.In the case, be arranged on decorate with characteristic layer on protective layer used in protecting said decoration and characteristic layer.
Generally, these other different layer equally can be through applying the method that protective layer is applied on the jewel according to of the present invention being used for.
Protective layer itself can be transparent basically for the light of limit of visible spectrum.But can stipulate that also protective layer is colored and/or is provided with subject matter or mark, especially in order to satisfy decorative purpose.
Because finish at the jewel edge usually on every side in the reflecting layer on the jewel, so utilization is used the formation protective layer according to method of the present invention in these fringe regions material sense is great.The jewel edge can be the edge of the maximum cross section of girdle (Rondiste) or jewel, jewel from it towards the front and/or back side convergent.The reflecting layer is on the back side that is normally placed in jewel.Because finish mostly on the edge of before in the reflecting layer, so set protective layer needn't for edge itself.
Through using liquid protective layer material with the drop form to jewel according to the present invention, protective layer is administered on the respective regions of jewel targetedly and holding device does not together apply on being forced property ground.The common protective layer zone that particularly on holding device and jewel, does not occur linking up, jewel must split out from said protective layer zone when holding device removes.According to the present invention's regulation, the drop of the jet of liquid protective layer material has the essentially identical velocity of direction for this purpose, thereby jet can point to the zonule of jewel targetedly.Different with it, the drop in the spraying of shower nozzle does not have the velocity of qualification, but is more or less promoted mussily by so-called spraying.
These drops can form the jet that the protective layer material by liquid state constitutes, wherein, this jet can by partial association with constitute by not related drop, these drops strike on the jewel according to time sequencing.
Especially for being polished into jewel with facet; According to method of the present invention is favourable because especially spraying can make that the material that forms protective layer arrives jewel through nondirectional liquid drop movement according to the method for prior art those should not set the facet in the zone of protective layer.But this is undesirable from aesthetic reasons in addition.Utilization can be given the seamed edge protective mulch according to method of the present invention through optionally spraying targetedly better.
Especially can stipulate to industrial manufacturing that utilize according to method of the present invention and not only give a jewel armor coated, and apply many jewels as far as possible simultaneously, to this, holding device has many supports that are used for each jewel.
Other favourable embodiment of the present invention limits in the dependent claims.
As stated, the edge in reflecting layer is started the problem of being mentioned especially and is received the threat of when splitting out the jewel that is coated, together being torn at least in part.
From this reason, stipulate that in an embodiment of the invention the material that forms protective layer is administered on the edge in reflecting layer at least partly, thereby the protective layer that the edge in reflecting layer is hardened hides or covers.Preferably, the edge in reflecting layer is not only partly but along the covered or covering with protective layer of its whole periphery.
The material that replacement will form protective layer is administered on the edge in reflecting layer; Also can stipulate in another embodiment; The material that forms protective layer is arranged in the interior zone on surface, reflecting layer, thereby the fringe region in reflecting layer is vacated in application and protective layer material of no use hides.As a result, the zone of vacating of the not protected seam material at edge, reflecting layer covering is removed.Can stipulate a kind of engraving method for this purpose,, not damage or only slightly damage jewel itself though this engraving method removes the reflecting layer in the corresponding position from jewel.The zone that the quilt at edge is vacated is so removed, that is, protective layer hides or cover the new edge that forms owing to remove in reflecting layer.
Can stipulate that also the new edge in reflecting layer produces through removing the zone, reflecting layer that has covered with protective layer material.But can also stipulate that at this edge protected seam of the new formation in reflecting layer hides or covers.In order especially to remove the reflecting layer, be employed in method well known in the prior art.
Using the material that forms protective layer so targetedly is feasible owing to applying the drop with substantially the same direction vector.
In order to realize can stipulating also will better the hiding of edge, reflecting layer, at least one is located at second protective layer on the protective layer and for example is coated with according to method of the present invention with the form utilization of another enamelled coating and installs on the jewel zone.Can stipulate that at this first protective layer temporarily hardens, use the liquid protective layer material that is used for second protective layer with liquid form then.
In a preferred implementation of the present invention, jewel in using the process of protective layer, be maintained on the surface of holding device or within.Can stipulate now that according to the present invention these drops are administered on the jewel along the direction perpendicular to holding device at least partly basically.If for example holding device has the recess that during coating procedure, is used for one or more jewels, this means that then drop uses along remain on outside wherein recess imaginary the terminal perpendicular to jewel at least partly in the jewel zone.If having jewel, holding device keeps plane above that; Holding device for example is configured to transmit the support plate of film, sieve plate or other form in other words, and then standard solution drops in this embodiment of the present invention along being administered on the jewel about the vertical direction in this plane.
If jewel has desktop in its front; And the back side that is provided with the reflecting layer in case of necessity has the tip, then jewel can with its desktop be set in the recess of holding device or the flat area supported of holding device on and the drop of material that forms protective layer along using being held under the state that device keeps perpendicular to the direction of jewel desktop.If jewel has front and the girdle that the back side separates with jewel, can stipulate that then the drop of material that forms protective layer is along using in being held the state that device keeps perpendicular to the direction of the imaginary plane through the jewel girdle.At this, girdle is meant the maximum edge of diameter of jewel, and wherein, this edge can be configured to seamed edge or edge surface, for example cylindrical.Can use the formation protective layer material equably through such method, and avoid the drop of banking motion for example as in spraying, to strike on the positive zone that should not set protective layer.
Stipulate that in another embodiment of the present invention the material that forms protective layer is not only to be applied on the zone at whole edge in some zones or reflecting layer at edge for example, but is administered on the entire emission layer of jewel.Be provided with reflecting layer and its edge at least in part by the given jewel of girdle for its back side, wherein rear surface faces is used the used device of drop, can stipulate, gives the whole back side with armor coated according to mode of the present invention.In contrast to this, the front towards holding device can not have protective layer material basically.After making jewel, watch this jewel through the front.The back side opposite with the front is provided with the reflecting layer at least in part, the mirror-polishing faces towards surface jewel of the reflection ray in this reflecting layer.According to the present invention, on the side that deviates from it in reflecting layer, use matcoveredn.
In a preferred implementation of the present invention, the material of formation protective layer optionally is administered on the jewel zone with the form of drop.Through optionally using,, can be especially targetedly use jewel vacating under the situation of holding device for example through optionally spraying.Optionally be applied in this and mean that the drop of protective layer material is to semiprecious specific region.For this reason needn't be covered owing to use targetedly or be arranged in the holding device in the zone of vacating.
But can expect also that usually the drop of protective layer material is applied on the jewel with the form of even shower, wherein, drop has substantially the same direction.Can make holding device and jewel so directed thus; Making does not have drop to strike simultaneously on the fringe region of jewel and holding device; Thereby avoid layer related on holding device and jewel, and jewel needn't be split out in order to remove from holding device by layer from such association.
In a special preferred implementation of the present invention, stipulate, spray the material that forms protective layer to jewel from the outlet opening of the nozzle of printhead.This printhead itself be in the prior art known and be used for office or industry conventional ink-jet printer (so-called industrial inkjet printer) be used for print paper or planar textile configuration fabric.Printhead can have many separately controllable nozzles at this, and these nozzles have an outlet opening respectively, and the material that forms protective layer comes out from outlet opening.If especially a plurality of jewels should be set protective layer simultaneously, then can stipulate to implement with such device according to method of the present invention, this device is not to include only a printhead but comprise complete a series of in case of necessity by the printhead of parallel control.
Have up to the method for 90 degree and bigger subtended angle different with material that spray to form protective layer and spraying; The material of formation protective layer very accurately occurs with little subtended angle from the outlet opening of the nozzle of printhead, and can be for example through turning to electrode to be diverted on the desired site of jewel.
In a special preferred implementation of the present invention, protective layer material is made up of paint or protective layer material comprises paint.For this purpose, can use traditional, known paint itself is used for jewel in the prior art.Particularly can be the paint that can harden through actinism that can commercial buy, for example so-called UV cured lacquer.
Especially transparent protective layer or the transparent for example so-called glass ink of enamelled coating is provided for according to method of the present invention as protective layer for the light of visible range.However also can use the enamelled coating or the protective layer that constitute by paint colour or dyeing at least.
Protective layer material flows out from the outlet opening of nozzle with the drop form, wherein, the drop of outflow itself basically along same direction with approximate speeds and therefore have approximate momentum, if drop mass is similar to equally.Nozzle can so constitute at this, makes drop optionally point to the jewel zone.Jet can be made up of incoherent drop at this, perhaps comprises discontinuous drop.In the case, each drop of protective layer is coated with on the zone of for this reason establishing that installs to jewel with approximate momentum.Can stipulate at this, be used for the outlet opening of protective layer drop and the distance that should set between the jewel zone of protective layer keeps as far as possible for a short time.In an embodiment of the invention, the size of this distance less than 5 centimetres, preferably less than 2 centimetres, be more preferably less than 1 centimetre.
Very well be applicable to less jewel according to method of the present invention, this less jewel is impaired very easily because split out the protective layer that links up on jewel and holding device that beginning is mentioned in addition.Especially diameter is 0.5 millimeter to 25 millimeters, the jewel that is preferably 0.5 millimeter to 10 millimeters can utilize according to method of the present invention armor coated.
In an embodiment of the invention, the material use continous inkjet method that forms protective layer is used.This method also is called as high-pressure process, and wherein, the drop that comes out from the nozzle of printhead has high flying speed.The coating time that prevents spraying thus and realize weak point.
In yet another embodiment of the present invention, the material of formation protective layer is applied on the jewel zone with the need based jet method.This need based jet method comprises: the piezoelectric ink jet method, and wherein, the drop of protective layer material is produced by piezo-activator; Perhaps bubble jet method, wherein, the drop of protective layer material is produced by thermal actuator; Perhaps valve control method.This means that for adopting such printhead according to method of the present invention, this printhead is according to known in the prior art method work own and utilize this method to produce jet.Also can adopt the multiinjector system of parallel control.The printhead of working according to the method also has mostly and is used to device that drop is turned to, utilizes these devices can make these drops optionally point to the jewel zone.
In yet another embodiment of the present invention; At the protective layer material of liquid state, preferably in paint, be distributed with granular solids; Thus protective layer can uniform deposition on jewel; And under the situation that is polished into jewel, in facet, do not form the meniscus (Meniskus) that constitutes by protective layer material with facet, that is have the protective layer zone of arcuate surface, and the seamed edge between the facet keeps not having protective layer.
Shortcoming at this is, when the content of this solid was high, these solids demonstrated inhomogeneity, and this possibly be the blastocyte of corrosion and for little jewel, visually also can see.
As stipulating in yet another embodiment of the present invention; If form the material of protective layer now, promptly especially paint at first is applied on the jewel and this material of at first using partially hardened or be hardened to a certain degree owing to hardening at least application after vacating under the situation in space; Continue to use the material that forms protective layer then, then prevent to form the meniscus that links up that is in one of the jewel complete facet or the surface of the arch that links up on the big zone at jewel.The space that is not provided with protective layer as yet between two drops that are applied on the jewel can be filled with other protective layer material now.Because these spaces are significantly less than the whole zone that will set protective layer of jewel, so the arch that occurs owing to the surface tension of protective layer is obviously less.
In the zone of the seamed edge between two facets of a jewel and in tip region, the embossment (Relief) of the drop of the subsclerotic or hardening of formation protective layer material, this embossment is filled through the protective layer material that covers seamed edge subsequently.If form the material of protective layer evenly be coated with install on the seamed edge or the jewel tip on; Then may occur that; Promptly cross over seamed edge or the most advanced and sophisticated surface that forms the arch that constitutes by protective layer material; The surface of this arch tear fracture in hardening process, so these zones finally are not provided with protective layer.Through vacate the zone of at first giving seamed edge or most advanced and sophisticated both sides under seamed edge or the most advanced and sophisticated situation set protective layer material and only before the protective layer material that applies drip just for seamed edge or most advanced and sophisticated zone after the partially hardened at least or the protective layer material of injection liquid state; Arch is obviously less, thereby avoids the above-mentioned damage in the zone at seamed edge or tip.In the case, can also abandon solid additive independent in liquid protective layer material or can at least obviously reduce this solid additive because the hardening of protective layer material or subsclerotic drop substitute this solid.
The sclerosis of protective layer material or crosslinked can be at this through using ray, especially ultraviolet ray or realizing through local heat or cooling.Be configured at protective layer under the situation of enamelled coating, for this reason can use itself known can be through UV cured lacquer or lacquer that can thermmohardening, for example one pack system lacquer.Also can use double compositions paint, this double compositions paint hardens through contacting with second component that causes or quicken to harden.This second component can be when being used first component or is applied on the jewel afterwards.In order to harden, can in protective layer material, be added on the material that melts when using protective layer and cool off thus and harden through cooling.Hardening process can comprise one or more process steps.Given method for curing and the combination of own known sclerosis supplementary means in the prior art also are feasible.
Also can stipulate, before being applied on the jewel, in material, sneak into solvent and/or dispersant, and the evaporation of sclerosis through this solvent or this dispersant realizes.Such paint is known as solvent paint usually.Baking finish also is feasible as disperseing lacquer, and sclerosis realizes through the evaporation of heat affecting and/or solvent or dispersant in this baking finish.
Because the characteristics according to method of the present invention are; The material that forms protective layer can very accurately be applied on the desirable zone of jewel, thus can through the part intentinonally the coating protection layer material come to protect more equably for example seamed edge between gemstone facet and the most advanced and sophisticated perhaps edge in reflecting layer of jewel.Thereby according to an embodiment of method of the present invention in, the amount of the material that the parametric optimization of coating procedure is to be used and/or hardening parameter are selected according to geometry jewel, that especially should use the zone of protective layer above that.That the parameter of these and selected relating to parameters comprises seamed edge girdle for example, between the facet and jewel position and the orientation most advanced and sophisticated or edge, reflecting layer.For this purpose, the geometry of jewel can be stored in the electronic memory and can preferably automatically be considered for confirming the parameter of coating procedure.
Can be provided with the one scan device at this, utilize this scanning means to detect geometry jewel and/or the reflecting layer and also this geometry is stored in the electronic memory.Utilize this information to make coating be adapted to key position as described above.This adaptation through the parameter of selecting coating procedure realizes is carried out at this electronic data-processing equipment capable of using automatically.
In an embodiment of the invention, set protective layer as described above for the jewel have towards the zone of most advanced and sophisticated convergent.But the zone of these convergents needn't necessarily be converged to a tip.In other words, also can stipulate, to have with frutum for example the jewel of the taper that constitutes of the shape of pyramid or frustum apply.At this, the material that forms protective layer is applied on the outside of the taper region that also is provided with the reflecting layer on it with liquid form at least partly.On the zone of these convergents, be provided with the reflecting layer.The zone of convergent is provided with respect to the imaginary plane with maximum cross section obliquely.
But can stipulate that also the material that forms protective layer is arranged on the reflecting layer at least partly, this reflecting layer is placed in again on the face that laterally arranges with imaginary plane through girdle or with the desktop of jewel.For example it can be as brilliant (Rose) the known jewel of lotus at this.
The invention still further relates to a kind of jewel with front and back, wherein the back side at least in part, preferred be provided with most ofly the reflecting layer and at least on the edge in reflecting layer or the edge that surpasses the reflecting layer be applied with protective layer.Protective layer hides or covers the edge in reflecting layer thus.When covering, the back side of end, reflecting layer and jewel directly are capped and protect simultaneously or be capped and protect at the layer that is arranged on below the reflecting layer on the jewel.Protective layer can especially utilize aforesaid method to apply at this.
Edge through present regulation protective layer is made up of the drop of the sclerosis of the material that applies with liquid form that forms protective layer, can protect with respect to corrosion and other external environment influence edge of responsive reflecting surface especially.Can stipulate that at this edge of protective layer is made up of the drop of indivedual sclerosis of liquid protective layer material, the protective layer drop that is perhaps applied exchanges and sclerosis then each other.Edge according to protective layer of the present invention is made up of the drop interflow and sclerosis then in the case.By comparison, the jewel that has the reflecting surface that is provided with protective layer above that has zigzag and uneven fringe region, and the edge of this protective layer forms through from bigger coherent protective layer, splitting out jewel.In addition owing to from bigger layer, split out, the edge of protective layer even the edge that possibly be configured such that reflecting surface expose or even the reflecting layer in the process of splitting out, partly break away from from jewel.
Therefore on the edge of reflecting surface, have smooth end according to jewel of the present invention, for example with protuberance or half protuberance form, this end is the disconnection that does not occur enamelled coating in other words of not breaking off.Not the drop through sclerosis but have zigzag and rough trend through splitting out the edge that forms from bigger layer.
Preferred regulation, the edge of reflecting surface is arranged in the girdle zone, and this girdle separates the front of jewel with the back side.In order to realize protecting particularly well the reflecting layer, stipulate that preferably the edge that surpasses the reflecting layer is provided with the edge of protective layer or protective layer, the edge protected seam covering and the protective layer in reflecting layer stretch out above the reflecting layer thus.At this, protective layer also can slightly protrude in girdle and overlap on the front.Also can realize protection thus to girdle.The edge of protective layer forms through the drop of many sclerosis, can arrange protective layer equably thus.
Of the present invention one preferred embodiment in, protective layer is arranged on the entire emission layer, wherein, especially the edge of protective layer by the sclerosis drop constitute.Because the mirror-polishing in reflecting layer is towards jewel, so protective layer is arranged on the side that deviates from jewel in reflecting layer that is on the back side in reflecting layer.
Preferred regulation also, protective layer is an enamelled coating, is made up of paint in other words or comprises paint at least.
In an embodiment of the invention, jewel itself is made up of glass, and this glass is enough to satisfy the visual requirement for jewel, but still is favourable at manufacture view.But also can use natural or synthetic jewel or half precious gems for the present invention.
Jewel can be polished at this has facet, special anaclasis effect can on the seamed edge between the facet, occur thus, and this anaclasis effect especially causes through the light reflection on the reflecting layer of protected layer protection.The reflecting layer this can be arranged on a plurality of convergents, be shrunk on the zone at a tip.The example of this jewel is a rock quartz.But the reflecting layer also can be arranged on the face that is arranged in parallel with imaginary plane through girdle or with desktop.The example of this jewel is known as the lotus crystalline substance.
Of the present invention another preferred embodiment in, at least the reflecting layer towards the side of jewel by mirror-polishing, thereby those light that pass the front that deviates from the reflecting layer are settled in the reflecting layer on the back side at place and are reflected.Mirror-polishing for example is used to improve the radiance of jewel in the case.The side that deviates from jewel in reflecting layer, be that the back side is provided with according to protective layer of the present invention.
