Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] See figure 1 —— Figure 7 , the diamond with 81 facets of the present invention comprises: a crown, a pavilion and a girdle 2 connecting the crown and the pavilion, the number of the crown facets is 51, the number of the pavilion facets is 30, and the girdle 2 is circular The number of auxiliary small facets is 65-100, a total of 81 main facets and 65-100 auxiliary small facets.

[0029] The crown has a symmetrical structure: the top of the crown has a table top 1, the side of the crown has 10 crown hexagonal main cutting surfaces 3, 10 crown trapezoidal main cutting surfaces 4, 10 crown shield-shaped main cutting surfaces 5 and 20 quadrilateral main cutting surfaces 6 on the upper waist of the crown.

[0030] See figure 1 , Figure 7 , the two vertices of the crown hexagonal main cutting surface 3 are respectively located on the table 1 and the waist 2, an...

Abstract

The invention relates to the technical field of diamonds, in particular to a diamond with 81 cutting surfaces. The diamond with 81 cutting surfaces comprises a crown part, a pavilion part and a waist which is connected with the crown part and the pavilion part; the crown part comprises 51 main cutting surfaces; the pavilion part comprises 30 main cutting surfaces; the total number of the main cutting surfaces is 81; the waist is circular; 65 to 100 auxiliary small cutting surfaces are formed in the longitudinal direction of the waist; the crown part is of a symmetrical structure: a crown top is provided with one table surface; the side surface of the crown part is provided with 10 crown part hexagonal main cutting surfaces, 10 crown part trapezoidal main cutting surfaces, 10 crown part peltate main cutting surfaces and 20 crown part upper waist quadrilateral main cutting surfaces; the pavilion part is of a symmetrical structure: 10 pavilion part quadrilateral main cutting surfaces which share the same vertex, and 20 pavilion part lower waist main cutting surfaces; the auxiliary small cutting surfaces of the waist are of quadrilateral structures; the light of the diamond can be transmitted and reflected in all directions; the brightness, the lustre degree and the twinkling degree of the diamond are high; the patterns of ten heart-shaped shapes and ten arrows can be observed.

Description

technical field [0001] The invention relates to the technical field of diamonds, in particular to an 81-cut diamond. Background technique [0002] The refractive index of diamond is very high, and the dispersion is also very strong. However, it needs to be carefully crafted by the polisher to emit unparalleled light. Most of the traditional diamonds on the market now have 57 facets and round brilliant cuts. It consists of three parts: the waist (frosted edge), 33 facets on the crown, and 24 facets on the pavilion. The traditional diamond cutting and polishing process, the waist is rough, the cutting facets are relatively small, the diamond light cannot be transmitted and reflected in all directions, the number of refractions is small, and the brightness, fire and scintillation are relatively dim. [0003] Therefore, how to achieve all-round transmission and reflection of light, reasonably and effectively improve the brightness, fire and scintillation of diamonds, and show t...
