Embodiment approach

[0051] In a further embodiment of the present invention, the diamond cutting method includes:

[0052] S1: Provide a rectangular-cut diamond to be processed, the girdle of the diamond to be processed has four interconnected and rectangular long sides 1, and a corner 2 is defined between each two adjacent long sides 1;

[0053] S2: Select a long side surface 1, rough cut this long side surface 1, and remove part of the material of the diamond to be processed close to the long side surface 1 from the direction of the long side surface 1 to the center of the diamond to be processed, so as to be in the original length A rough-cut waist surface 11 is formed near the position of the side surface, wherein the two ends of the rough-cut waist surface 11 have a first distance a and a second distance b between the corners 2 of the two ends of the long side surface 1;

[0054] S3: finish cutting and trimming the rough-cut girdle 11, so that the rough-cut girdle 11 forms a first girdle 12 ...

Abstract

The invention discloses a diamond cutting method and a diamond. The diamond cutting method comprises the following steps that S1, the to-be-processed diamond is provided, the waist portion of the to-be-processed diamond is provided with four long edge faces which are connected to one another and are in a rectangular shape, and a corner is defined between every two adjacent long edge faces; S2, one long edge surface is selected, and a part of material, close to the long edge surface, of the diamond in the direction from the long edge surface to the center of the to-be-processed diamond is removed so as to form a rough cutting waist surface near the original position of the long edge surface; and S3, the rough cutting waist surface is finely cut and finished, so that the rough cutting waist surface forms a first waist surface and a second waist surface which are perpendicular to the crown surface of the to-be-processed diamond and are adjacent to each other, one end of the first waist surface is connected to one end of the second waist surface, the other end of the first waist surface forms a molded line of one corner, and the other end of the second waist surface forms a molded line of the other corner. According to the diamond cutting method and the diamond, the star-shaped diamond diamond outer contour line is provided, meanwhile, weaker-light edge parts of princess cut cutting are reduced, and refracted light is concentrated towards the middle part of the diamond to form sparkling star-shaped light.

Description

technical field [0001] The invention relates to the technical field of diamonds, in particular to a diamond cutting method and a diamond obtained by the cutting method. Background technique [0002] With the development of the diamond processing industry, the precision of diamond cutting is getting higher and higher, and different diamond cutting shapes and technologies have come out one after another. However, the commonly used diamond cuts in modern times include round multi-faceted cuts, princess cuts, oval cuts, heart cuts, radiant cuts, etc. With the increasing demand for diamonds, it is no longer possible to just Staying in the conventional form, so cuts such as nine hearts and one flower, ten hearts and ten arrows, and plum blossom diamonds have appeared successively in the past century. Too many transformations. Taking Blue Flame as an example, it has 89 cutting faces, 32 more than the standard round diamond, table width ratio is 50-65%, total depth ratio is 65-72%...
