Embodiment 1

[0021] Embodiment 1: a kind of processing method of jewelry color diamond, comprises steps as follows:

[0022] Step 1. Use graphite powder to add contact coal (graphite powder: contact coal 7:3), and synthesize a large single crystal through high temperature and high pressure (temperature 1773°C, pressure 6.3GPa);

[0023] Step 2. use the cutting method (cutting, grinding the outer circle, grinding plane) of the natural jewelry drill for the large particle single crystal that has been synthesized to make such a Figure 1a ,or Figure 1b ,or Figure 2a ,or Figure 2b ,or Figure 3a ,or Figure 3b ,or Figure 4a ,or Figure 4b ,or Figure 5a ,or Figure 5b ,or Figure 6a ,or Figure 6b The man-made jewelry colored diamond shown has a structure whose surface is composed of mutually symmetrical planes intersecting each other, or has a main plane surrounded by symmetrical planes, or has a vertex or a straight line with a vertex Or a straight line is centered and surround...

Embodiment 2

[0024] Embodiment 2: the present invention adopts the large particle single crystal that the high temperature and high pressure synthesis that the step 1 of embodiment 1 obtains is processed into jewelry color diamond, has the following steps:

[0025] Step 1. Select 0.05ct-10ct synthetic diamond single crystal, density: 3.515, hardness: HV7000-10000.

[0026] Step 2. Using the cutting method of natural jewelry drill, cut out such as Figure 1a ,or Figure 1b ,or Figure 2a ,or Figure 2b ,or Figure 3a ,or Figure 3b ,or Figure 4a ,or Figure 4b ,or Figure 5a ,or Figure 5b ,or Figure 6a ,or Figure 6b Shown is a natural jewelry drill.

Abstract

The invention relates to colorful artificial diamond for ornaments and a processing method thereof. Graphite powder and accelerant are synthesized to big single crystal under high temperature and high pressure; the synthesized big single crystal is made to colorful artificial diamond by the cutting method of natural diamond for ornaments. The ratio of the graphite powder to the accelerant is 7 to 3, and the big single crystal is synthesized under the temperature of 1773 DEG C and the pressure of 6.3GPa. The structure of the colorful artificial diamond for ornaments is round, heart-shaped, cockleboat-shaped, egg-shaped, western pear-shaped or blue jade-shaped. In view of the problems of less and less natural diamond and higher and higher price, the colorful artificial diamond for ornaments that is processed from synthetic diamond single crystal can overcome the defects that natural diamond has less material and high price and meet the need of wide consumers.

Description

technical field [0001] The invention relates to a jewelry colored diamond and a processing method thereof. The invention relates to the application and value of processing a synthetic diamond single crystal into a jewelry diamond. Background technique [0002] With the continuous exploitation of the earth's resources by human beings, there are fewer and fewer natural materials, and natural diamonds (for industry and jewelry) are also facing the same problem. [0003] People's quality of life is constantly improving, and the demand for decoration is increasing, but the high price of natural diamonds discourages the common people, and the scarcity of colored diamonds makes the rich lament. Contents of the invention [0004] In order to overcome the deficiencies of the above-mentioned prior art structure, the present invention provides a jewelry colored diamond and a processing method thereof. [0005] The technical scheme that the present invention solves technical problem ...
