Problems solved by technology

[0009] However, whether it is the traditional square improved sparkle cutting method or the method disclosed in patent 201610184745.7, the table top is too large and the facets are too few, which directly affects the refraction of the fire, and it also seems a bit monotonous

Embodiment

[0037] A processing method for an improved princess cut diamond, comprising the steps of:

[0038] 1) Refer to figure 1 with figure 2 Cut the table top. That is, according to the design requirements, the tabletop 1 is cut out on the rough diamond 2. Because the surface of the tabletop 1 is irregular, the tabletop that is cut out is also an irregular square (see figure 2 );

[0039] 2) Grinding the square. Grind the four sides of the square towards the waist respectively, and grind out the square cone used to form the waist (see image 3 with Figure 4 ); then sand the waist 3. The waist height accounts for 15% of the total height of the quadrangle.

[0040] 3) Grinding the pavilion (see Figure 5-9 ). Grind the triangular facet 4 parallel to the waist at 55 degrees, polish the waist thickness to account for 10% of the total height of the square, and make the four waist lines even; A large facet 5. After the grinding is completed, looking up from the bottom to the ...

Abstract

The invention discloses a processing method of an improved princess cut diamond, comprising the following steps: (1) cutting the tabletop, (2) grinding the square, (3) grinding the pavilion, (4) processing the face, adopting the method of the present invention The processing method, on the one hand, can process an ordinary round diamond of 70 points into a finished product of one carat diamond, and the value of the diamond can be correspondingly increased by 2000-6000 yuan; After the diamond-shaped kite surface spliced ​​by equilateral triangles, the light refraction effect of the princess-cut diamond is improved, the brightness and fire of the diamond are improved, and the layering of the original princess-cut table is stronger. The brilliance can be increased by 10-15%, making the diamond shine brightly.

Description

technical field [0001] The invention belongs to the technical field of diamond processing, and in particular relates to a processing method of an improved princess cut diamond. Background technique [0002] Among the many special-shaped diamonds, princess cut diamonds are widely welcomed in the European and American markets because of their unique meaning and fire color that is not inferior to round diamonds. In the US diamond trade in 2005, princess cut diamonds accounted for 20% of total diamond sales, but in 1997 princess cut diamonds only accounted for a mere 5%. [0003] The traditional processing method of princess cut diamonds, i.e. square modified sparkle cut method or brilliant processing method, generally includes the following steps: [0004] (1) Cutting the desktop, that is, cutting out a substantially square desktop on the diamond blank according to the design requirements; [0005] (2) grinding the cube, grinding towards the waist direction with four sides of...
