Problems solved by technology

However, because synthetic moissanite and diamonds have objective differences in refractive index and dispersion, compared with diamonds of the same specification, moissanite can only be "similar in shape" but not "similar in spirit".
Taking the classic 57-sided round diamond as an example, compared with the natural diamond round diamond, the moissanite round diamond of the same size will produce the visual effect of ghosting of the rear facet ridge line, which seriously affects the shopping experience of users. In order to make the synthetic carbon Silica is more perfect. According to the properties of moissanite material, study the facet cutting technology of this carbon silicon round diamond to remove ridges and ghosting

Embodiment 1

[0040] A moissanite round diamond includes a crown, a girdle, and a pavilion; the girdle is between the crown and the pavilion, and the crown includes 1 large table 1, 8 equal kite faces 2, 8 equal star facets 3, 16 equal upper girdle facets 4; the pavilion includes 16 equal lower girdle facets 5 and 8 equal sword facets 6, and its table width ratio is 55%; Its crown height is 14.1%; its girdle height is 3%; its pavilion height is 44.3%; its kite facet 2 angle is 55.1°; its star facet 3 angle is 70°; its upper girdle facet 4 angle is 44.5°; the 5 angles of the lower waist facets are 47.2°; the 6 angles of the sword facets are 49.2°.

Embodiment 2

[0042]A moissanite round diamond includes a crown, a girdle, and a pavilion; the girdle is between the crown and the pavilion, and the crown includes 1 large table 1, 8 equal kite faces 2, 8 equal star facets 3, 16 equal upper girdle facets 4; the pavilion includes 16 equal lower girdle facets 5 and 8 equal sword facets 6, and its table width ratio is 56%; Its crown height is 14.5%; its girdle height is 4%; its pavilion height is 44.7%; its kite facet 2 angle is 55.4°; its star facet 3 angle is 70.5°; its upper girdle facet 4 angle is 45°; the lower girdle facet 5 angle is 47.4°; the sword facet 6 angle is 49.4°.

Embodiment 3

[0044] A moissanite round diamond includes a crown, a girdle, and a pavilion; the girdle is between the crown and the pavilion, and the crown includes 1 large table 1, 8 equal kite faces 2, 8 equal star facets 3, 16 equal upper girdle facets 4; the pavilion includes 16 equal lower girdle facets 5 and 8 equal sword facets 6, and its table width ratio is 57%; Its crown height is 14.8%; its girdle height is 5%; its pavilion height is 45.1%; its kite facet 2 angle is 55.8°; its star facet 3 angle is 71°; its upper girdle facet 4 angle is 45.5°; the lower girdle facet 5 angle is 48°; the sword facet angle is 49.7°.

[0045] The optical effect of Cupid’s 8 arrows can be observed from the front of the above three moissanite round diamonds through the cutting mirror.

Abstract

The invention discloses a moissanite round diamond. Requirements on a cutting direction and a cutting included angle of a raw material blank body are as follows: by taking X axis and Y axis as standards, a cutting angle is 43 to 45 degrees by taking the Y axis of a crystal as the standard in a raw material crystal cutting process; a raw material crystal is cut into blank bodies with correspondingsizes according to specifications needed by cutting; 2) a cut and engraved surface of the round diamond comprises a crown part, a waist part and a pavilion part; the waist part is located between thecrown part and the pavilion part. According to the moissanite round diamond provided by the invention, a processing flow is adjusted so that a defect that post-engraved surface ridges between synthetic moissanite and a diamond have ghosting is overcome, so that a 57-faced round diamond prepared from the synthetic moissanite also can realize a clear Cupid 8-arrow optical effect that the post-engraved surface ridges have no ghosting.

Description

technical field [0001] The invention relates to a diamond substitute, and relates to the technical field of a moissanite round diamond and a processing method thereof, in particular to a method for cutting a moissanite round diamond with faceted ridges and ghosts after removal. Background technique [0002] Because of its rarity, crystal clear characteristics and the implication of eternity, diamond has always been known as the king of gems and the best raw material for jewelry. But its high price discourages the general public. As a substitute for diamonds, synthetic moissanite has a cost price far lower than that of natural diamonds, and its physical properties such as hardness, luster, fire color, and high thermal conductivity are very close to diamonds, and most of them surpass diamonds. It can also be easily owned, and has become a new favorite in the jewelry industry in recent years. However, because synthetic moissanite and diamonds have objective differences in ref...
