Description

八方钻石Octagonal diamond

技术领域Technical field

本申请涉及珠宝领域，具体的说是一种八方钻石。This application relates to the field of jewellery, and in particular to an octagonal diamond.

背景技术Background technique

钻石是指经过琢磨的金刚石，也就是说钻石是将金刚石经过加工得到的一种具有独特形状、亮光和火彩的珠宝。因其材料的稀缺和不可再生，以及美好的寓意，钻石具有极高的市场价值。Diamonds are honed diamonds, which means diamonds are jewels with unique shapes, brilliance and fire. Due to the scarcity and non-renewability of its materials, and the good meaning, diamonds have a very high market value.

钻石的形状有已知的如圆形、蛋形、梨形、橄榄形、公主方形、祖母绿形等。不同形状的钻石都有其独特性。The shape of the diamond is known as a circle, an egg, a pear, an olive, a princess, an emerald, and the like. Different shapes of diamonds have their own uniqueness.

对于钻石而言，钻石鉴定4C标准是国际上通常采用重量(克拉)、色泽、明澄度(透明度)、切工标准来衡量钻石的优劣标准。For diamonds, the diamond identification 4C standard is the international standard for weighing (carat), color, clarity (transparency), and cutting standards to measure the quality of diamonds.

由于颜色、净度、重量是钻石形成时自身的性质，无法改变，因此只有切工才能赋予钻石更好的品质和价值，并赋予钻石更灿烂的光芒。Because the color, clarity and weight are the nature of the diamond when it is formed, it cannot be changed. Therefore, only the cutting can give the diamond better quality and value, and give the diamond a brighter glow.

但是，将裸钻加工成为价值连城的钻石过程中，钻石最终能保留的重量很大一部分还是与切工有关。However, in the process of processing loose diamonds into valuable diamonds, the final weight of the diamonds is still a large part of the cut.

公主方形切割是花式切割的钻石之一，外观呈方形，优点在于它能更加充分地利用钻石毛坯，使钻石看起来比圆形钻石要大10％到15％。由于独特切割，在同等分数下，方钻的台面比例要比圆钻大。但是，正是因为公主方钻是四面等边、棱角对称的正方形，因此，要想得到完全对称的公主方形钻石，钻坯的利用率还不够完全，还是会损失一部分原料。再者，也是因为钻石的方正的形状，在镶嵌时边角易破碎，从而大大降低了饰品的价值。Princess Square Cut is one of the fancy cut diamonds. It has a square appearance. The advantage is that it makes fuller use of the diamond blank, making the diamond look 10% to 15% larger than the round diamond. Due to the unique cutting, the proportion of the table top of the square drill is larger than that of the round diamond under the same score. However, it is precisely because the princess diamond is a square with four sides and equilateral angles. Therefore, in order to obtain a completely symmetrical princess-shaped diamond, the utilization rate of the rough is not complete enough, and some raw materials will be lost. Moreover, because of the square shape of the diamond, the corners are easily broken during the setting, which greatly reduces the value of the jewelry.

中国在先专利申请《具有八心八箭图案的改进的公主方形钻石及方法》，申请公布号为CN 103932462 A，此钻石包括1个台面、4个冠部主刻面、8个冠部腰小面、8个冠部星形刻面、4个冠部副刻面、8个冠部副腰小面、8个亭部主刻面、4个亭部副刻面、16个亭部腰小面和1个腰部。China's prior patent application "Improved Princess Square Diamonds and Methods with Hearts and Arrows", application number is CN 103932462 A, this diamond includes 1 table top, 4 crown main facets, 8 crown waists Facet, 8 crown star facets, 4 crown face facets, 8 crown waist facets, 8 pavilion main facets, 4 pavilion side facets, 16 pavilion waists Facet and 1 waist.

此改进形的公主方形钻石提供了一种解决上述钻坯利用率不高、边角易碎问题的方案。但是，钻石价值的体现，在很大程度上要求其具有独特性，也就是与众不同。This modified princess-cut diamond provides a solution to the problem of low utilization of the drill blank and fragile corners. However, the embodiment of the value of diamonds requires a great degree of uniqueness, that is, it is different.

通过以上各个刻面的角度设置，可以尽可能将射入钻石内部的光线经过多次折射和反射，使得钻石更加明亮，火彩更强。并且，各个刻面的角度设计并不是简单经过有限次试验就能获得的，各个刻面的角度设计一方面需要复合光的折射和反射原理，并且，冠部的刻面尽可能要将从亭部反射或折射回来的光线再次经冠部刻面反射，增加光线在钻石内部的反复反射，这样才能使得钻石更加明亮，火彩更强。此外，此种钻石在保持钻石完美亮光与火彩的同时，保留了钻石的最大直径，用同样大小的毛坯钻石得到最大的成品钻石，且可以大大避免钻石在镶嵌时边角易破碎的情况。Through the angle setting of each of the above facets, the light incident into the inside of the diamond can be refracted and reflected as many times as possible, so that the diamond is brighter and the fire color is stronger. Moreover, the angular design of each facet is not simply obtained through a finite number of tests. The angle design of each facet requires the principle of refraction and reflection of the composite light on the one hand, and the facet of the crown should be as far as possible from the kiosk. The reflected or refracted light is again reflected by the facet of the crown, increasing the repeated reflection of light inside the diamond, so that the diamond is brighter and the fire is stronger. In addition, this diamond retains the diamond's maximum diameter while maintaining the perfect brightness and fire of the diamond. The same size of rough diamond is used to obtain the largest finished diamond, and the diamond can be greatly prevented from being broken when the corner is inlaid.

本申请还提供一种八方钻石的切割方法，图5和图6，包括以下步骤：The present application also provides a method for cutting an eight-sided diamond, and FIG. 5 and FIG. 6 include the following steps:

(1)切割台面：根据钻石毛坯(图5.1)的基本形状，把钻石毛坯切割出一个大平面，作为钻石的台面，参见图5.2。(1) Cutting table: According to the basic shape of the diamond blank (Fig. 5.1), the diamond blank is cut into a large plane as the table top of the diamond, see Figure 5.2.

(2)切割腰部刻面：将切割好台面的钻石毛坯按照其形状从长边开始或短边开始加工腰部刻面，使得台面成为正方形，形成4个第一腰部刻面21，参见图5.3-5.4，腰部的厚度为钻石宽度的15-17％,例如可以为15.5％、16％、16.5％等，本领域技术人员可根据实际需要设置(钻石的宽度是指钻石的两条长腰部边线之间的距离)；再垂直切去腰部的4个角，参见图5.5-5.6，也就是腰部的4个顶角，形成4个第二腰部刻面22(第一腰部刻面21和第二腰部刻面22与台面垂直)，切去的角的边长占腰部边线边长的20％，使得台面成为对称的八边形，参见图5.7，腰部刻面形成间隔设置的长腰部边线和短腰部边线，相对应的第一腰部刻面21和第二腰部刻面22也是间隔设置。第一腰部刻面21对应的是长腰部边线，第二腰部刻面22对应的是短腰部边线。第一腰部刻面21和第二腰部刻面22均为长方形。此处需要说明的是，由于腰部的刻面为细长，为了显示刻面的形状，本说明附图中的腰部刻面做了处理，并非实际钻石的加工尺寸。(2) Cutting the waist facet: The diamond blank of the cut table surface is processed according to its shape from the long side or the short side to process the waist facet, so that the table top becomes a square, forming four first waist facets 21, see Figure 5.3- 5.4, the thickness of the waist is 15-17% of the width of the diamond, for example, may be 15.5%, 16%, 16.5%, etc., the person skilled in the art can set according to actual needs (the width of the diamond refers to the two long waist edges of the diamond) The distance between the two), then cut the four corners of the waist vertically, see Figure 5.5-5.6, which is the four apex angles of the waist, forming four second waist facets 22 (first waist facet 21 and second waist) The facet 22 is perpendicular to the table top. The length of the cut corner is 20% of the side length of the waist, so that the table becomes a symmetrical octagon. See Figure 5.7. The waist facets are formed with a long waistline and a short waist. The side line, the corresponding first waist facet 21 and the second waist facet 22 are also spaced apart. The first waist facet 21 corresponds to a long waistline and the second waist facet 22 corresponds to a short waistline. The first waist facet 21 and the second waist facet 22 are both rectangular. It should be noted here that since the facet of the waist is elongated, in order to show the shape of the facet, the waist facet in the drawing is processed, which is not the actual size of the diamond.

(3)切割亭部主刻面：将切割好腰部刻面的钻石毛坯从远离台面的长腰部边线与短腰部边线的交点沿着长腰部边线延伸取一个点，使得此点与交点之间的长度占长腰部边线长的13％，以相邻两个点之间的连线所在的面进行切割，使得切割面与平行于台面的腰刻面的角度为40.5-41.5°，参见图5.8-5.10；再以相邻长腰部边线和短腰部边线的中点之间的连线所在的面进行切割，使得切割面与平行于台面的腰刻面的角度为40.5-41.5°，参见图5.11-5.12；形成8个亭部主刻面。(3) Cutting the main facet of the pavilion: the diamond blank cut from the waist facet is extended from the intersection of the long waist line and the short waist line away from the table along the long waist line to make a point between the point and the intersection. The length is 13% of the length of the long waistline, and the surface of the line connecting the two adjacent points is cut so that the angle between the cutting surface and the waist facet parallel to the table is 40.5-41.5°, see Figure 5.8- 5.10; then cut the surface of the line between the adjacent long waist line and the midpoint of the short waist line so that the angle between the cut surface and the waist face parallel to the table is 40.5-41.5°, see Figure 5.11 5.12; Form 8 main facets of pavilions.
