Description

Diamond with 65 cutting surfaces

Technical Field

The utility model relates to a diamond, in particular to a diamond with 65 cutting surfaces.

Background

The traditional diamond on the market mostly has 57 cutting facets, is mainly cut in a circular bright mode and consists of 3 parts, namely, 24 facets, namely a crown facet, a waist facet and a pavilion facet. In the traditional diamond cutting and polishing process, the cutting facets are fewer, the times of light transmission, reflection and refraction through the diamond are fewer, and the brightness, the fire chroma and the flicker are dull.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model provides a diamond pavilion portion structure of improvement on the basis of ancient ways cutting cuts into 65 faces with the diamond, improves the diamond firelight, and the end point part has adopted non-traditional cutting, produces the flower shape shadow effect.

The technical scheme is as follows: the utility model discloses a diamond with 65 cutting surfaces, including crown, pavilion and the waist of connecting crown and pavilion, the number of crown cutting surfaces is 33, and the pavilion cutting surface is 32, totally 65 cutting surfaces;

the crown part is of a symmetrical structure: the crown part is provided with a table top, 8 star surfaces, 8 kite surfaces and 16 upper waist surfaces; the star surface is triangular, and three edges of the star surface are respectively connected with the desktop and the 2 kite surfaces; the kite surface is quadrilateral, two vertexes are respectively positioned on the waist and the desktop, and four edges of the kite surface are respectively connected with 2 star surfaces and 2 upper waist surfaces; the upper waist surfaces are triangular, two adjacent upper waist surfaces share one edge, and the other two edges of the upper waist surfaces are connected with 1 kite surface and the waist;

pavilion is symmetrical structure: the pavilion is provided with 8 pavilion cutting surfaces sharing a vertex, 8 pavilion side cutting surfaces and 16 lower waist surfaces; the cutting surfaces of the pavilions are 6-sided, two adjacent cutting surfaces of the pavilions share one edge, and the other 4 edges of the cutting surfaces of the pavilions are respectively connected with 2 cutting surfaces on the side surfaces of the pavilions and 2 lower waist surfaces; the pavilion side face cutting surfaces are quadrilateral, one vertex of each pavilion side face cutting surface is positioned on the waist, four sides are respectively connected with 2 pavilion side face cutting surfaces and 2 lower waist faces, and 2 symmetrical lower waist faces are arranged between two adjacent pavilion side face cutting surfaces; the pavilion lower waist surface is provided with four edges, two adjacent lower waist surfaces share one edge, and the rest edges are respectively connected with the girdle, the pavilion cutting surface and the pavilion side surface cutting surface.

The ratio of the width of the table top to the waist diameter is 33-45%; although the facet distribution manner of the CROWN (CROWN) is similar to that of the bright type cutter, the distribution ratio of each facet is greatly different, and generally speaking, the judgment standard of the bright type cutter defines the table width ratio as 50-66% and regards the table width ratio as VG and above, that is, the table size occupies half to two thirds of the widest waist (girdled) size of the whole diamond and regards the table size as a very good cutting ratio. The aspect ratio of the diamond of the present invention is controlled to be between 33-45%, i.e. the size of the table occupies one third to nearly one half of the widest waist (girdled) dimension of the whole diamond. From this ratio requirement, it can be seen that the difference in the ratio of crown division for two different cutters is very significant, and is two completely different cutter requirements.

The ratio of the thickness of the waist to the diameter of the waist is 2-4.5%, the utility model discloses a higher price/performance ratio has improved the technology degree of difficulty, controls the waist thickness between 2-4.5%.

The crown angle is 34-37 degrees. The pavilion angle is 39-43 degrees. The utility model discloses simultaneously through the location of hat angle and the positioning control of pavilion angle, with the refraction control of light at the optimum, such requirement has increased a small amount of cost and the processing degree of difficulty, has nevertheless changed the splendid firer.

Has the advantages that: the utility model discloses a mode that the adjustment of special cutting proportion and pavilion portion increase the facet produces better shadow effect, improves lithodomous glaring degree with more tangent planes simultaneously, gives the more queen cell impression additional value of product, increases the core competitiveness of enterprise, and the outside imitation degree of difficulty is high.

Detailed Description

As shown in fig. 1, 3, 4, 5 and 6, the diamond consists of a crown, a pavilion and a girdle 1 connecting the crown and the pavilion, and 65 cutting surfaces are provided, wherein the crown is provided with a

table top

2, 8

triangular star surfaces

3, 8 quadrangular kite surfaces 4 and 16 triangular upper girdle surfaces 5; three edges of the star surface are respectively connected with the desktop and the 2 kite surfaces; two vertexes of the kite surface are respectively positioned on the waist and the desktop, and four edges are respectively connected with 2 star surfaces and 2 upper waist surfaces; the adjacent upper waist surfaces share one edge, and the other two edges of the upper waist surfaces are respectively connected with 1 kite surface and the waist.

The pavilion has 8 common-vertex 6-edge pavilion cutting planes 6, 8 quadrilateral pavilion side cutting planes 7 and 16 quadrilateral lower waist planes 8; two adjacent pavilion cutting surfaces share one edge, and the other 4 edges of the pavilion cutting surfaces are respectively connected with 2 pavilion side cutting surfaces and 2 lower waist surfaces; one vertex of the pavilion side face cutting face is located on the waist, four edges are respectively connected with 2 pavilion side face cutting faces and 2 lower waist faces, 2 symmetrical lower waist faces are arranged between two adjacent pavilion side face cutting faces, two adjacent lower waist faces share one edge, and the rest edges are respectively connected with the waist, the pavilion side face cutting faces and the pavilion side face cutting faces.

As shown in FIG. 2, the ratio of the width d1 of the table top to the waist diameter d2 is 33-45%; the ratio of the waist thickness g to the waist diameter d2 is 2-4.5%. Crown angle c is 34-37 degrees, pavilion angle p is 39-43 degrees, pavilion height is h1, and crown height is h 2. The location of crown angle and the location control of pavilion angle control the refraction control of light at the optimum state, have more bright firer.
