Embodiment 1

[0037] Example 1 (round diamond)

[0038] A diamond processing method, comprising the steps of,

[0039] (1), desktop cutting, cutting out the desktop 10 on the diamond blank 101 (see figure 2 );

[0040](2), the waist is formed, and the waist 20 is polished on the rough diamond 101 (see image 3 );

[0041] (3) Bottom processing, on the diamond blank, the part below the waist 20 is processed into an approximately conical bottom (30); specifically, based on the datum plane 31 of the waist 20, the first included angle α is 45 degrees- At 48 degrees, the part next to the waist 20 is ground into 8 equal bottom surfaces 32, and the height h1 corresponding to the bottom surface 32 accounts for 20%-40% of the height h from the reference plane 31 of the waist 20 to the top 33 of the bottom 30 ( See Figure 4 and Figure 5 );

[0042] (4), on the basis of the 8 bottom surfaces 32, select 4 mutually symmetrical bottom surfaces 32 and polish the pick-up surface 34 with the s...

Embodiment 2

[0048] A diamond processing method, comprising the steps of,

[0049] (1) Cutting the desktop, cutting out the desktop on the rough diamond;

[0050] (2) The waist is formed, and the waist is polished on the rough diamond;

[0051] (3) Bottom processing, on the diamond blank, the part below the waist is processed into an approximately conical bottom; specifically, for oval ( Figure 9 ) or marquise ( Figure 10 ) diamond, with the datum plane of the girdle as the reference, the part next to the girdle is polished into 6 bottom surfaces at a first included angle, wherein the first included angle adopted by the first bottom surface 51 and the second bottom surface 52 is 40°-42°; the angle of the first included angle adopted from the third bottom surface to the sixth bottom surface 53, 54, 55, 56 is 37°-39°; the height h1 corresponding to the bottom surface occupies the reference plane from the waist to the bottom 70%-80% of the height h of the top; on the basis of the 6 botto...

Embodiment 3

[0053] A diamond processing method, comprising the steps of,

[0054] (1) Cutting the desktop, cutting out the desktop on the rough diamond;

[0055] (2) The waist is formed, and the waist is polished on the rough diamond;

[0056] (3) Bottom processing, on the diamond blank, the part below the waist is processed into an approximately conical bottom; specifically, for the pear shape ( Figure 11 ) diamonds, with the datum plane of the girdle as the reference, the part immediately adjacent to the girdle is polished into 7 bases at the first included angle, among which, the first base to the fifth base 61, 62, 63, 64, 65 The first included angle adopted is 40°-42°; the first included angle adopted by the sixth and seventh bottom surfaces 66, 67 is 37°-39°; the height corresponding to the bottom surface occupies the reference plane of the waist to the bottom 70%-80% of the height of the top of the top; on the basis of the 7 bottom surfaces, the sharpened surface is polished at ...

Abstract

The invention relates to a diamond processing method, which comprises the following steps of cutting a table, forming a girdle, processing a pavilion, and processing a crown, wherein the processing of the pavilion adopts a composite processing method, the reference surface of the girdle is used as the reference, a part near the girdle is ground into N bottom surfaces at a first included angle (alpha), and N is greater than or equal to 6; the ratio of the corresponding height (h1) of the bottom surface in the height (h) from the reference surface of the girdle to the tip of the pavilion is that the ratio of round diamonds is 20-40%, and the ratio of elliptical, olive-shaped, pear-shaped and heart-shaped diamonds is 70-80%; culet forming surfaces are ground at a second included angle (beta) on the basis of N bottom surfaces; at least 2N bottom foot surfaces are ground at a third included angle on the basis of ridges formed by two adjacent surfaces; the first included angle (alpha) is greater than the second included angle (beta). The diamond processing method has the advantages that the good bright and luster of the diamond are maintained, and the maximum weight of the diamond is also maintained.

Description

technical field [0001] The invention relates to a diamond processing method, in particular to a diamond processing method which can increase the weight of a diamond product. Background technique [0002] A rough diamond looks inconspicuous. It must be carefully cut, polished and processed before it can become the shining diamond that people are used to. Therefore, the processing of diamonds directly affects the value of diamonds. The most ideal cutting effect is of course to preserve the maximum weight of the diamond, minimize flaws, and fully display the beauty of the diamond so that the diamond shines. [0003] Common diamond shapes are generally divided into round, heart-shaped, oval, pointed and pear-shaped. Regardless of the overall shape of the diamond, its processing includes the following basic steps: [0004] (1) Cutting the desktop, that is, cutting out the desktop 100 on the rough diamond according to the design requirements (see figure 1 , figure 1 Only the ...
