Definitions
- the present invention relates to a cut gem comprising a first predetermined number of facets cut in the crown and a second number predetermined facets cut in the cylinder head around an axis of symmetry central geometric.
- the gem in particular the cut diamond, points to the observer an image with a general hexagonal symmetry and a set of light reflections and six-pointed star differential colorings where the lobes send shimmering optical effects to the observer.
- the gem consists of diamond or stone with a refractive index and a dispersion roughly equal to those of diamond.
- optical effects of light effects are obtained particularly important.
- said central geometric axis of symmetry corresponds to one of the axes of ternary crystallographic symmetry of the diamond.
- This feature makes it easier and safer to size the table. by cleavage of the diamond along one of the faces of the octahedron.
- the quality of the size of the facets can thus be predetermined and be carried out with great precision.
- the invention also relates to a method for cutting a gem, by peculiar to a diamond characterized by the fact that we first cut all the facets of the crown and the cylinder head and that we then cut the lobed perimeter of the rondist by performing the lobed form with six portions in rounded projection and six rounded hollow portions.
- Figures 1, 2 and 3 are top, bottom and side views of a first mode of execution.
- FIG. 4 represents certain characteristics of the external contour of the first mode executioner.
- Figures 5, 6 and 7 are top, bottom and side views of a second mode of execution.
- the cut gem shown in Figures 1 to 3 is a diamond and includes a crown 10 and a cylinder head 11 separated by a rondist 12.
- the shape geometric cut of this diamond has a hexagonal symmetry with in as a main element of symmetry a hexagonal axis of rotation 14. The facets of the size are therefore arranged around this axis according to an arrangement hexagonal.
- This axis of geometric symmetry preferably corresponds to one of the axes ternary crystallographic of the crystal structure of the diamond, if the shape geometric of the rough diamond to be cut allows it.
- Table 16 and the plan of the rondist 12 will therefore be parallel to one of the facets of the diamond octahedron gross, which will make it possible to obtain the location of table 16 by cleavage of the rough diamond, avoiding tedious sawing as is generally the case necessary when the table is perpendicular to one of the crystallographic axes of order four of the diamond.
- the contour 20 of the rondist 12 seen perpendicular to the hexagonal axis 14, as illustrated in FIG. 4, has a lobed shape with six projecting portions rounded 21 and six rounded hollow portions 22.
- the rondist 12 has a maximum outside diameter D, a minimum inside diameter Di and a diameter medium Dm intermediate.
- the projecting portions 21 have a radius of curvature r2 which is substantially equal to 0.125 D, while the radius of curvature r3 of recessed portions 22 is substantially equal to 0.062 D.
- the crown 10 includes a table 16 with a hexagonal outline or substantially hexagonal depending on the size precision.
- First six facets triangular 25 each share one of their edges with an edge of the table.
- Six second facets 26 are inserted between the first facets and six third facets 27 share one of their edges with a second edge facets 26 and make the connection with the rondist 12.
- the cylinder head 11 has six fourth facets 28 and twelve fifths facets 29 arranged near the rondiste on either side of the edges separating the fourth facets, and six sixth facets 30 arranged near the base 31 partially between two neighboring fourth facets 28.
- the second, third and fourth facets 26, 27, 28, as well as the recessed portions 22 of the rondist are arranged in a first position identical angular around the hexagonal geometric axis, while the first and sixth facets 25, 30 and the projecting portions 21 are found in a second angular position offset by 30 ° from the first angular position. There is therefore a predetermined correspondence between the facets of the crown, those of the cylinder head and the outline of the rondiste.
- the height H of the gem cut between its table and its base is preferably between 0.55 and 0.75 D, advantageously 0.6 D.
- the height Ht of the crown above the plane of the rondist is preferably 0.13 D, and the height Hc of the cylinder head is preferably 0.47 D.
- the first 25, respectively second 26, respectively third 27, respectively fourth 28 and sixth facet 30 respectively make angles included between 10 ° and 25 °, respectively 10 ° and 25 °, respectively 25 ° and 35 °, respectively 35 ° to 55 ° and respectively 25 ° to 35 °.
- the third and fourth facets 27 and 28 on the one hand and on the other of the rondist make an angle of 30 ° and 42 ° with the plane of the rondist 12.
- the method of cutting this gem firstly involves obtaining of the table, preferably by cleavage parallel to one of the faces of the octahedron and then, after the bruting, the size of the different facets of the crown and the breech.
- This cut is made of preferably using a laser cutting device.
- the surfaces of cutting of the rondiste 12 are then polished and cleaned until all traces of carbon black spots due to laser burns have missing.
- the weight of the cut diamond retains approximately 25 to 30% of the weight of the cut diamond. rough diamond; this size therefore does not have a high yield.
- diamonds cut according to this size allow to obtain total reflections internal with hexagonal and lobed image structure and shape, which gives the gem new and original optical effects.
- This symmetry hexagonal combined with total internal reflections on the facets of the breech and a differential refraction on the facets of the crown allows obtain a remarkable and original fire due to its hexagonal distribution and peripheral lobes.
- the second embodiment illustrated in Figures 5 to 7 also includes a crown 10 and a cylinder head 11 separated by a rondist 12.
- the assembly also has a hexagonal geometric shape with an axis of symmetry hexagonal central 14 around which the facets are arranged in a hexagonal symmetry.
- the axis of geometric symmetry can preferably also correspond to one of the ternary axes of symmetry of the structure diamond crystallography.
- Rondiste 12 also has a lobed shape with six rounded projecting portions 21 and six rounded recessed portions 22, the radii of curvature can be similar to those of the first embodiment.
- the crown 10 has here, instead of a table, an apex 50 formed by six first triangular facets 55 arranged in a first position angular around the hexagonal geometric axis 14.
- Six second facets 56 are arranged in a middle position along a second angular position offset by 30 ° from the first angular position and six third facets arranged near the rondist according to the first angular position.
- the breech 12 has twelve fourth facets 58 arranged near the rondist 12 and twelve fifth facets 59 forming the base 61 and arranged each between two fourth facets in an angular position offset by 15 ° compared to that of the fourth facets.
- the recessed portions 22, the first and the third facets 55, 57 and half 58a of the fourth facets are arranged in the first position angular.
- the projecting portions 21, the second facets 56 and the other half 58B fourth facets are arranged in the second angular position.
- the height H between the apex 50 and the base 61 is between 0.5 and 0.75 times the outside diameter D of the rondist 12.
- this height H, that Ht of the crown and that Hc of the cylinder head are 0.52 D, 0.18 D and 0.35 D.
- the first 55, respectively second 56, respectively third 57, respectively fifth facets 59 do with the plane of the rondist of angles between 8 ° and 20 °, respectively 20 ° and 27 °, respectively 20 ° and 32 °, respectively 30 ° to 50 °.
- second and fifth facets 56 and 59 on either side of the rondist make a 23 ° and 34 ° angle with the plane of the rondist 12.
- the cutting process is similar in that the facets are first cut of the crown 10 and of the cylinder head 11 around the hexagonal axis 14, which preferably corresponds to the crystallographic ternary axis of the diamond, and that we then cut the lobed perimeter of the rondiste preferably with a laser.
- the embodiments described above do not have no limiting nature and that they can receive any modifications desirable within the framework as defined by claim 1.
- the cutting according to the invention can also be carried out on other stones and gems with similar refractive index and dispersion, or roughly equal to those of diamond. It may be necessary to adapt the angles of inclination of the facets taking into account the refractive indices of the substitute stones. Thus, the angles of the facets can also be changed according to the shape of the rough stones. Other additional facets can be added. These facets may only be as appropriate number of three per type of facets. The cutout of the rounder may also be obtained by any other suitable means.
