Description
Technical Field
The invention relates to the field of jewelry, in particular to a diamond with twelve 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 patent adopts an accurate cutting process and a facet design of a crown part, so that the diamond forms a rose shape under the irradiation of light; the crown part and the pavilion part can see rose light shadows under the overlooking condition through special angle design, eleven planar rose light shadows are formed at three main light angles appearing at the joint of two adjacent crown main surfaces, the aesthetic feeling of the diamond is improved, and the using effect and the using benefit of the diamond structure are effectively guaranteed.
Jewellery is the pursuit of lovers 'elements in love, while butterflies are lovers' loyalty, have only one partner in a lifetime, and are one of the representatives of insect world faithfulness, and butterflies are regarded as the symbol of good luck and beauty by people, such as butterflies loving flowers are often used for sweet love and happy marriage, and the pursuit of mankind to being good at beauty is expressed. For the diamond, people want to have a diamond which can show a butterfly shape and a flower shape inside the diamond without damaging the conical shape of the diamond, and the diamond is combined together, so that the moral is more beautiful, and the scene is beautiful and unreasonable, so that new varieties of butterfly diamond series are increased.

Taking a waist reference plane as a reference: the first sole surface 3 and the waist reference surface form a first included angle alpha, and the value range of the alpha is 41.5-42.5 degrees; the second bottom rake tip surface 31 and the waist reference surface form a second included angle beta, and the value range of the beta is 35-39 degrees.
In the diamond, the main crown surface 12 and the waist reference surface form a third included angle gamma, and the value range of gamma is 32-38 degrees; the triangular kite surface 13 and the waist reference surface form a fourth included angle omega, the value range of omega is 28-33 degrees, or the height h2 of the upper waist triangular surface accounts for 50% -70% of the distance from the waist to the table board 1; the first upper waist triangular surface 14 and the second upper waist triangular surface 15 form a fifth included angle phi with the waist reference surface, and the value range of phi is 40-44 degrees.
The invention also provides a method for processing the diamond with the twelve butterfly patterns in the interior, 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;
the step 3 comprises the following steps:
3.1 As shown in fig. 3, the plane of the waist is taken as a reference plane which is parallel to the plane of the table board 1, twenty-four first plantar surfaces 3 are ground towards the middle lower part of the waist at a first included angle alpha, and the twenty-four first plantar surfaces 3 intersect at a cone tip point 301. The twenty-four first plantar surfaces 3 and the waist present a twenty-four pyramid, but the waist is finally ground to be round;
3.2 based on the intersected ridge 302 of two adjacent first sole surfaces 3, with the cone cusp point 301 as the starting point, respectively polishing a first second sole cusp surface 31 towards two sides of the ridge 302 by a second included angle beta or according to a first preset length h1, as shown in fig. 4, which is a plane; and (3) polishing one second bottom rake pointed surface 31 according to the two first bottom rake faces 3, and polishing twelve second bottom rake pointed surfaces 31 as shown in fig. 5, wherein each second bottom rake pointed surface 31 is a quadrangle. In fig. 4, the first second bottom rake tip surface 31 is not a quadrangle, because the second bottom rake tip surface 31 is a plane in the drawing, and the plane is modified into a quadrangle, which results in disorder in the drawing, the first second bottom rake tip surface 31 in the drawing is not a quadrangle, and a quadrangle can be ground in an actual working process, so that part of the adjacent second bottom rake tip surfaces 31 are ground; however, it is not necessary to grind the second floor rake faces 31 into a quadrilateral shape, because as long as each second floor rake face 31 is ground into a plane, a quadrilateral shape is formed naturally. Preferably, the second bottom rake tip surface 31 is diamond-shaped.
Since the length of the second bottom rake face 31 to be ground is h1, and the second bottom rake face 31 is quadrilateral, when the first second bottom rake face 31 is ground, the conical tip 301 formed by the intersection of twenty-four first bottom foot faces 3 is already ground, but for the sake of understanding, we assume that the conical tip 301 exists until the twelfth second bottom rake face 31 is finished.

4.4 based on the rest of the ridge 101 intersected by the two main crown surfaces 12, polishing a first upper lumbar triangular surface 14 towards the center of the main crown surfaces 12 by taking the intersection point 103 of the ridge 101 intersected by the two main crown surfaces 12 on the lumbar circular plane as a starting point and a fifth included angle phi as shown in FIG. 9.
4.5 grinding a second upper lumbar triangle surface 15 towards the center direction of the other main crown surface 12 by a fifth included angle phi on the basis of the ridge 101 of the main crown surface 12 which is not ground in two adjacent main crown surfaces 12 in 4.4 and the intersection point 104 of the ridge 101 on the lumbar circle plane as a starting point on the basis of 4.4 as shown in fig. 10, wherein the second upper lumbar triangle surface 15 is symmetrical to the first upper lumbar triangle surface 14 by the ridge 101, and the first upper lumbar triangle surface 14 and the second upper lumbar triangle surface 15 are called as a first pair of upper lumbar triangle surfaces 16;
4.6 polishing a second pair of upper triangular surfaces 16 and a third pair of upper triangular surfaces 16 by a method for polishing the first pair of upper triangular surfaces 16 as shown in fig. 11 until the twelfth pair of upper triangular surfaces 16 are polished;
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 predetermined length h1 is 20% -50% of the distance from the bottom tip 33 to the waist 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 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. In fig. 1, b is 53-57% of a, c is 16.2% of a, d is 43.1% of a, the waist height accounts for 2-3% of a, angle a is 98 °, angle b is 34 °, and angle c is 40 °.

4.2 on the basis of 4.1, grinding a first triangular kite surface (13) by using a fourth included angle omega or according to a second preset length h2 with the table top (1) as a starting point on the basis of an intersected edge of two adjacent main crown surfaces (12); two end points (102) of the triangular kite surface (13) on the table board (1) are located at the midpoint of the intersection line of the main crown surface (12) and the table board (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 board (1);
4.3 grinding twelve triangular kite surfaces (13) by a method of grinding a first triangular kite surface (13);
4.4 based on the rest section of the ridge (101) of the main crown surface (12), 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 ridge (101) intersected with the two main crown surfaces (12) 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 edge (101) of the main crown surface (12) which is not ground in two adjacent main crown surfaces (12) in 4.4 as a symmetry axis and an intersection point (103) of the edge (101) on 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 twelfth pair of upper triangular surfaces (16) are polished;
4.8 the waist is ground into a round shape.
