Problems solved by technology

[0002] The current faceted gemstones determine their cut shape according to their unique physical and optical properties, while traditional gemstone facets are designed and ground in a flat shape. This grinding method may achieve an ideal effect on high-refractive index gemstones. Optical effect, while the middle and low-grade gemstones with low refractive index often follow the cutting shape of high-grade gemstones, so they cannot give full play to their unique optical properties.

Embodiment

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] (1) Use an ordinary gemstone grinding and polishing machine to preform the crystal and grind and polish the table top [1], and then use traditional processing methods to grind the 8 main facets [3] and 8 star facets [2] on the crown of the gemstone. ] Grinding is completed, the angle of the main facet [3] of the crown is ground out according to the conventional angle of the gemstone variety, and all the facets are polished to complete the processing of the crown;

[0020] (2) The pavilion of the gemstone is also ground at a conventional angle to produce 4 pavilion left main facets [4] and 4 pavilion right main facets [5]. The pavilion must be pointed, and all facets do not need to be polished;

[0021] (3) Put the polished gemstones in the wooden seat that can fix the gemstones, and then use a pendant drill with a flexible shaft to carve, and use...

Abstract

This invention discloses groove internal reflection carving gem processing technique. Preform the secondary and inferior gem, grind and polish for tabletop [1]; grind multiple main facets [9] and star facets [2] on gem crown and polish all facets; grind multiple left main facets [4] and right main facets [5] on middle part of gem, the middle part must shrink to tine; carve the grooves of left and right main facets; finally, polish. The crown part has only star facets and crown facet besides tabletop, which not only ensures gem has color big block, but also decreases process and saves cost, makes the incision achieve most perfect optical and visual effect and exploits its potential market value.

Description

technical field [0001] The invention relates to a gem processing technology, in particular to a groove internal reflection cut gem processing technology. Background technique [0002] The current faceted gemstones determine their cut shape according to their unique physical and optical properties, while traditional gemstone facets are designed and ground in a flat shape. This grinding method may achieve an ideal effect on high-refractive index gemstones. Optical effect, while low-grade gemstones with low refractive index often follow the cut shape of high-grade gemstones, so they cannot give full play to their unique optical properties. The reason why middle and low-grade gemstones are listed as middle and low-grade gemstones is not only because of their large number, but also because of their inappropriate cutting shape, which is one of the main reasons for degrading their status. Therefore, it is imminent to study the cut shapes of middle and low grade gemstones. Improvi...
