Description

Fall high trapezoidal and fall high triangle jewel

The present invention is that a kind of new jewel is cut the mill style, by the jewel style that bizet, booth portion, table top, waist etc. are partly formed, is to be used to instruct jewel to cut the technology that the mill jewel is cut in grinder factory workshop.

Cut the mill field at jewel, bright type (being the jewel style that designs for the optical property that makes outstanding jewels such as the bright fire of jewel is color strong) jewel design style is always based on the design style of imitation diamond, and the present invention is the refractive index that is entirely outstanding jewel, optical properties such as chromatic dispersion and designing are in fact also broken away from the restriction of the former stone shape of diamond (the former stone overwhelming majority of diamond is squarish or sub-circular).

The high ladder type style that falls appeared at " Gem Studies " (Zhou Guoping chief editor with the title of the truncated cone, the publication of publishing house of China University of Geosciences) in the jewel style antique catalog (Fig. 2), but the character introduction that has only one deck (group) and there is no need because of its bizet facet, to such an extent as to both be difficult to operation, ground the optical property that also is difficult to outstanding jewel and cut.Triangle corner cut cut (Fig. 3) in " Gem Studies " style antique catalog is because the longitudinal axis height (Fig. 3) of institute's rescinded angle is too high.When wearing, can cause the jewel first half, have than large tracts of land and do not become clear, or become the black area according to the mode of correctly wearing of style of the present invention.In a word, because people are to falling high ladder type style research inadequately, though sometimes based on former stone type shape or the accidental shape that is similar to style of the present invention of wearing into of requirement of client, but owing to lack enough technical supports, the finished product that grinds also makes the optical property of jewel fully be showed or be difficult to good decoration effect with regard to being difficult to.

Purpose of the present invention, be for bright type jewel style before changing, wear when earrings, necklace, headwear, illumination from the wearer front upper place (embodies the illumination of bright type style jewel adornment effect, the overwhelming majority is from the wearer front upper place) after jewel reflection, have only seldom part to be observed by the people on opposite, to such an extent as to make the major part of jewel look bright inadequately or become shortcoming such as black area.Style of the present invention makes this problem obtain solution, also makes this optical property of chromatic dispersion of jewel obtain abundant performance simultaneously.

Technical scheme of the present invention is as follows:

So one, the present invention is called down high ladder type style and is meant that it faces the type shape is the isosceles ladder types, length-width ratio is greater than 1.4:1 (Figure 14), and when correctly wearing, must be that the short end (Fig. 4) is downward.

Two, the variation of the bizet that causes by waist limit angle (Fig. 5) of the present invention and booth portion facet angle is to the influence of the direction of propagation of the light that enters jewel, and the light that jewel is injected in the jewel front upper place that neutralized is the angle of refraction downwards.By adjusting the size of waist limit angle (Fig. 5), adjust the angle of the longitudinal axis (Fig. 6) direction of jewel reflection ray.Angle (Fig. 5) is big more, and the light that reflects tilts more upward, is easy to make the eyes of relative higher position to see more, and (Fig. 5) is more little for angle, and the light that reflects tilts downwards more, is easy to make the eyes of relatively low position to see more.

Owing to wear the difference of mode (wearing) in earrings, necklace, headwear etc., the gemstone refractive index difference, the equal reason of the build of wearing the jewellery people, when waist limit angle (Fig. 5) 9 ° 30 ' to 35 ° 30 ' scope in all have good decoration effect, and realize the present invention.

Three, by adjusting the angle of jewel bizet and booth portion facet, the angle of transverse axis (Fig. 6) direction makes the light that reflects be easy to be observed by the people on wearer opposite when adjusting reflection ray ejaculation jewel.The angle of bizet master facet is that the angle lap degree of cutting of 36 ° of (+-3 °) master of booth portion facets is 42 ° (+-2 °).

Four, following style can be realized the present invention, but has except the major defect person.

1, falls high ladder type (Fig. 1)

2, falling high triangular form (Fig. 7) extends to intersect and forms by falling the waist of high ladder type.Owing in style of the present invention, not requiring to falling facet of the short end of the short end of high ladder type and the bizet that therefore grinds thereof and booth portion facet of the short end, thus with the drift angle replacement of isoceles triangle type it, can not constitute influence to technical solution of the present invention.Fall the technical scheme of high ladder type described in this specification, can be directly applied for down high triangular form style.To the restriction of waist limit angle (Fig. 5) and be considered as to fall drift angle (Fig. 7) in the high triangular form style restriction and be suitable for.

3, rescinded angle is fallen high ladder type, cuts two jiaos (Fig. 8) or cuts four jiaos, (Fig. 9)

4, rescinded angle is fallen high triangular form (Figure 10)

5, rescinded angle is fallen high ladder type or the high triangular form institute rescinded angle of falling and cuts out once again, or for several times, or make down high ladder type the long end and (or) lack the end and become circular arc type, make down the end (Fig. 7) of high triangular form become circular arc type.(Figure 11 Figure 12 Figure 13)

6, in the above style, waist limit (Fig. 5, Fig. 7) is formed by connecting by two or two the above angles of cut minor faces less than 6 degree respectively.

7, above style, table top can be made up of less than the faces of 6 degree two or two above angles of cut.

8, the bizet facet of above style and booth portion facet can by the triangular form parallel or not parallel with the waist limit with waist limit (Fig. 5, Fig. 7) and (or) four jiaos of type facets form.

Meeting under the situation of above style, having following handicapped can have a strong impact on the quality of style of the present invention, thereby be not considered as having used the present invention.

1, bizet waist facet has only one group (layer).(Fig. 2)

2, length-width ratio is less than 1.4:1 (Figure 14).

3, rescinded angle fall high ladder type or rescinded angle fall the longitudinal axis height (Fig. 3) of high triangular form institute rescinded angle surpass jewel long 25%.

4, refractive index is greater than 2.1 jewel, and (such as diamond) is when grinding into style of the present invention, because the jewel chromatic dispersion is very little at the longitudinal axis (Fig. 6) direction start point, also just lose the relatively advantage of other jewel style of style of the present invention, therefore, also just be not considered as having used style of the present invention.The present invention is applicable to that refractive index is less than 2.1 and greater than 1.5 transparent jewel.

Style of the present invention has following useful effect

One, the chromatic dispersion of performance jewel (fire is color) aspect, because entering the polychromatic light of style jewel of the present invention is to scatter to the longitudinal axis and two directions of transverse axis (Fig. 6), so that the expressive ability of chromatic dispersion has obtained enhancing, make the color intensity of fire be better than the jewel of the same race of other style.Under the bigger situation of the dispersion values of jewel own, even can obtain the continuous effect that changes of the color that makes the monoblock jewel.

Two, former multiple bright type jewel style can only see under a light source when wearing that 30% to 50% part is bright, and style of the present invention under equal conditions, can see that the part 60% or more becomes clear.Also Just because of this, when the dark excessively gem processing of color became style of the present invention and correctly wears, it was many to allow the people think that color has shoaled.
