Problems solved by technology

After cutting, the round shape is changed into an octagon, allowing the light to enter the girdle and the refraction of the lower girdle to form a unique fire color overall, but the overall shape of the diamond is still approximately round, and there is no major breakthrough in shape

Embodiment approach

[0052] In a further embodiment of the present invention, the crown of the diamond to be processed has a trapezoidal surface 4 near each long side face 1, and the long side of each trapezoidal face 4 shares the molding line with a long side face 1, and each trapezoidal The short sides of the faces 4 all face the center of the diamond to be processed, and the bottom corners of each trapezoidal face 4 form part of a corner 2 .

[0053] In a further embodiment of the present invention, the arc top of the arc surface 12 is located inside the trapezoidal surface 4 .

[0054] In a further embodiment of the present invention, the arc top of the arc surface 12 is tangent to the short side of the trapezoid surface 4 .

[0055] In a further embodiment of the present invention, the arc top of the arc surface 12 is tangent to the short side of the trapezoidal surface 4 at the midpoint of the short side of the trapezoidal surface 4 .

[0056] In a further embodiment of the present inventio...

Abstract

The invention discloses a cutting method for a diamond with a radian and the diamond. The cutting method comprises the steps that S1, the to-be-machined princess-cut diamond is provided, the waist portion of the to-be-machined diamond is provided with four long edge faces which are connected with one another and are in a rectangular shape, the long edge faces are planes, and an angle is defined between every two adjacent long edge faces; S2, one long edge face is selected, and a material at the long edge face is removed, so that the long edge face forms an arc-shaped face which is sunken towards the center of the to-be-machined diamond; and S3, the step S2 is repeated until the four long edge faces form an arc-shaped face to obtain the finished diamond. Compared with a traditional princess square cut type cutting process, the cutting process has the advantages that the number of cut facets is large, the number of times of light transmission, reflection and refraction through the diamond is increased, the brightness and the brilliance are improved to a certain degree, and the process value of the diamond is increased.

Description

technical field [0001] The invention relates to the technical field of diamonds, in particular to a diamond cutting method with a curvature 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 dept...
