Description
Technical Field
The invention relates to the field of jewelry, in particular to a diamond with sixteen butterflies inside and a processing method thereof.
Background
Diamond parts:
diamond CROWN (CROWN): the upper part of the diamond, called the crown, comprises 1 TABLE (TABLE), 8 star facets (STARFACET), 8 kite facets (bezaficet) and 16 upper waist facets (UPPERGIRDLEFACET), for a total of 33 facets.
Waist circumference (GIRDLE): the widest part of the diamond is also the junction of the crown part on the upper surface of the diamond and the pavilion part under the diamond, and the waistline is the part for fixing the diamond when the jewel is inlaid.
The part under the PAVILION (PAVILION) diamond is called PAVILION, that is, the part from below the waist to the diamond tip. Comprises 16 waist planes (LOWERGERDLEFACET), 8 pavilion facets (PAVILIONFACET) and 1 bottommost base plane (CULET), and 25 facets in total; because the diamond does not necessarily have a pavilion with no pavilion, it has only 24 facets, and the total number of facets is 57.
For diamonds with the same size and cleanliness, in addition to the classic processing technique of the diamond, the cutting technique of the diamond is gradually marked by a unique cutting mode among brands. In pursuit of different sparkle types, different cutting styles present diamonds with different sparkle degrees, either more sparkling, such as brilliant, or more convergent, such as square, which look at the individual's orientation.
Two steps are essential for any diamond blank, namely 'scribing', 'valving and polishing'. The position and angle of the petals generated by a finely cut diamond are accurately calculated to maximize the brilliance of the diamond. It follows that cutting the hardest gemstone in the world, diamond, requires not only advanced equipment, but also a great deal of experience, high degree of responsibility and attention from the cutting engineer to release the full potential beauty of the diamond.
Standard round bright formula (standardroundbright):
the most common forms on the market include: 1 mesa, 8 kite facet, 8 star facet, 16 waist up facet, 16 waist down facet, 8 bottom main facet, and one sharp facet, which may or may not be present, for a total of 57 or 58 facets. Figure 1 clearly shows the specific location of the above facets of the diamond. Generally, a diamond of less than 5 carats has no point, so that the point of the Culet point on the certificate is None or Verysmall, etc., i.e. the point is None or negligibly small, i.e. 57 faces. In order to protect the diamond from damage, the large-particle diamond is generally flattened, so that one more surface, namely 58 surfaces, is provided. Many people often believe that the more facets a diamond is the better, and this is not true, and many types of gemstones are carved, especially shaped diamonds, which can extend over many facets, not all of which are the more facets the better. As a round drill, standard brilliant cuts (57-58 facets), also a classical lathe, are a very classic and perfect way of cutting.
Patent No. CN201811163063.3 entitled invention patent of diamond structure, discloses that the crown part 1 comprises 1 table top (11) on the top surface, the table top (11) is an undecamornate, each vertex of the table top (11) is provided with a hexagonal crown main surface (13) in the direction towards the waist (3), one vertex of the crown main surface (13) is located on the waist (3), the vertex of the crown main surface (13) on the table top (11) and the vertex on the waist (3) are two symmetrical points of the hexagonal crown main surface (13), and two adjacent crown main surfaces (13) share one edge; the pavilion (2) comprises 11 pavilion main surfaces (22) sharing vertexes, the pavilion main surfaces (22) are quadrilateral, one vertex of each pavilion main surface (22) is positioned on the waist part (3), and two adjacent pavilion main surfaces (22) share one side.

The invention also provides a method for processing the diamond with a sixteen-butterfly pattern inside, which comprises the following steps:
1, cutting a table board 1, and cutting a large plane on a drill blank to be used as the table board 1;
2, cutting the waist, and polishing the waist on the drill blank;
3, cutting the pavilion, and processing the part below the waist on the drilling blank into a bottom part which is approximately conical;
4, processing a crown part, namely processing the part above the waist part on a drilling blank into a crown part similar to a frustum shape;
and 3, cutting the pavilion, and processing the parts below the waist on the drilling blank into an approximately conical bottom, wherein the method comprises the following steps:
3.1 As shown in fig. 3, the plane of the waist is taken as a reference plane, the reference plane is parallel to the plane of the table board 1, thirty-two first plantar surfaces 3 are ground towards the middle and lower part of the waist at a first included angle alpha, and the thirty-two first plantar surfaces 3 intersect at the bottom tip 301. The thirty-two first underfoot surfaces 3 and the waist part form a thirty-two pyramid, but the waist part is finally ground into a circle;

4.7 the waist is ground to be round.
In the processing step, the first included angle alpha is selected from 41.5-42.5 degrees; the second included angle beta is selected from 35-39 degrees; the third included angle gamma is selected from 32-38 degrees; the fourth included angle omega is selected from 28-33 degrees; the fifth included angle phi is selected within the range of 40-44 degrees; the first preset length h1 accounts for 20% -50% of the distance from the bottom tip 301 to the waist part 2; the second predetermined length h2 is 50% -70% of the distance from the waist 2 to the table top 11.
The above-mentioned processing method is not the only processing method capable of processing the diamond, for example, the crown portion is processed and then the pavilion portion is processed; or a third corner surface is processed firstly, and then a second bottom rake tip surface 31 is polished; or the first upper waist triangular surface 14 or the second upper waist triangular surface 15 can be processed and polished firstly, and then the triangular kite surface 13 can be processed and polished; the processing sequence of the diamonds can be changed and the diamonds can be polished, and the processing sequence of the diamonds can be changed and combined in various ways due to multiple processing steps, so that the processing sequence is not repeated one by one.

3.1 taking the plane of the waist as a reference plane, wherein the reference plane is parallel to the plane of the table board (1), thirty-two first sole surfaces (3) are ground towards the middle lower part of the waist at a first included angle alpha, the first included angle alpha is selected from 41.5 to 42.5 degrees, the thirty-two first sole surfaces (3) are intersected at a sole tip (301), and the thirty-two first sole surfaces (3) form a thirty-two pyramid;
3.2 based on the intersecting edges (302) of two adjacent first bottom foot surfaces, and with the bottom tip (301) as a starting point, respectively polishing a first quadrilateral second bottom rake tip surface (31) to two sides of the intersecting edges (302) of the first bottom foot surfaces by using a second included angle beta or according to a first preset length h 1; then, sixty-six second bottom rake pointed surfaces (31) are ground on thirty-two first bottom foot surfaces (3) according to the same method; the angle of the second included angle beta is smaller than that of the first included angle alpha, the second included angle beta is selected from 35-39 degrees, and the first preset length h1 accounts for 20% -50% of the distance from the bottom tip to the waist;
and 4, processing a crown part, namely processing the part above the waist part on the drilling blank into a crown part similar to a frustum shape, wherein the method comprises the following steps:
4.1, grinding a table top (1) with sixteen regular edges and sixteen main crown surfaces (12) by aligning a crown part with a second bottom rake sharp surface (31) of the pavilion part at a third included angle gamma, wherein the third included angle gamma is selected between 32 and 38 degrees;
4.2 on the basis of 4.1, a first triangular kite surface (13) is ground by using a table top (1) as a starting point and using a fourth included angle omega or a second preset length h2 on the basis of an intersecting edge (101) of two adjacent main crown surfaces, the table top (1) is intersected with the first triangular kite surface (13), two end points (102) of an intersection line are positioned at the central position of a line of the main crown surface (12) and the table top (1), the fourth included angle omega is selected from 28-33 degrees, and the second preset length h2 accounts for 50% -70% of the distance from the waist to the table top (1);
4.3 grinding sixteen triangular kite surfaces (13) by a method of grinding a first triangular kite surface (13);
4.4 based on the rest section of the main crown surface intersecting arris (101), grinding a first upper waist triangular surface (14) towards the center direction of the main crown surface (12) by taking the intersection point (103) of the two main crown surface intersecting arris (101) on the waist circle as a starting point and a fifth included angle phi, wherein the fifth included angle phi is selected within the range of 40-44 degrees;
4.5 grinding a second upper lumbar triangular surface (15) symmetrical to the first upper lumbar triangular surface (14) towards the center direction of the other main crown surface (12) by taking an intersection point (103) of the intersection ridge (101) of the main crown surfaces (101) which is not ground in two adjacent main crown surfaces (12) in 4.4 as a symmetrical axis and taking an intersection point (103) of the intersection ridge (101) of the main crown surfaces and a lumbar circle as a starting point on the basis of 4.4;
4.6 two symmetrical first upper waist triangular surfaces (14) and second upper waist triangular surfaces (15) are called a pair of upper waist triangular surfaces (16);
4.7 polishing a second pair of upper triangular surfaces (16) and a third pair of upper triangular surfaces (16) by a method of polishing the first pair of upper triangular surfaces (16) until the sixteenth pair of upper triangular surfaces (16) are polished;
4.8 the waist is ground into a round shape.
