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

A kind of jewel color diamond and processing method

Technical field

The present invention relates to a kind of jewel color diamond and processing method, the present invention relates to be processed into application and the value that jewellery bore with the diamond synthesis monocrystalline.

Background technology

Along with the continuous exploitation of the mankind to earth resource, natural goods and materials are fewer and feweri, and rough diamond (industrial, jewellery with) also faces same problem.

People's quality of life is improving constantly, and is increasing to the demand of decorating, but the costliness of rough diamond allows common people hang back, and the in great shortage rich man of allowing of color brill loses and sighs.

Summary of the invention

In order to overcome the deficiency of above-mentioned prior art structure, the invention provides a kind of jewel color diamond and processing method.

The technical scheme that technical solution problem of the present invention is adopted is:

Comprise that step is as follows:

Step 1. adds with graphite powder touches coal, by synthetic big the monocrystalline of HTHP;

Step 2. with the cutting method that natural jewellery bore, is made artificial jewel color diamond with synthetic good large-particle monocrystal.

A kind of structure of jewel color diamond is round, heart type, bateau type, egg shape, western pears type or emerald type.

Beneficial effect of the present invention is specific as follows:

(1) diamond synthesis monocrystalline jewellery bore and are characterized as: main component C, and color is colored;

(2) diamond synthesis monocrystalline jewellery bore size 0.005～3ct, shape princess's cutting: round, heart type, bateau type, egg shape, western pears type, emerald type.

Fewer and feweri at rough diamond, price is more and more expensive, is processed into jewel color diamond with the diamond synthesis monocrystalline, has solved few, the expensive shortcoming of natural brill raw material, has satisfied consumers in general's demand.

Fewer and feweri in the face of natural brill, colored natural brill is phoenix feathers and unicorn horns especially, and is priceless.Be processed into the defective that jewel color diamond has equally also satisfied color brill with the diamond synthesis monocrystalline.

The specific embodiment

Embodiment 1: a kind of processing method of jewel color diamond comprises that step is as follows:

Step 1. adds with graphite powder touches coal (graphite powder: touch coal 7:3), by synthetic big the monocrystalline of HTHP (1773 ℃ of temperature, pressure 6.3GPa);

The cutting method (cutting, cylindrical grinding, flat surface grinding) that step 2. is bored with natural jewellery with synthetic good large-particle monocrystal, make artificial jewel color diamond shown in Fig. 1 a or Fig. 1 b or Fig. 2 a or Fig. 2 b or Fig. 3 a or Fig. 3 b or Fig. 4 a or Fig. 4 b or Fig. 5 a or Fig. 5 b or Fig. 6 a or Fig. 6 b, its structure is that the surface is made up of symmetrical plane, intersect between the plane, or a principal plane arranged, around principal plane, there is the plane of symmetry to center on, or a summit or straight line are arranged, be that the center has the plane of symmetry to center on summit or straight line.

Embodiment 2: the synthetic large-particle monocrystal of HTHP that the present invention adopts the step 1 of embodiment 1 to obtain, be processed into jewel color diamond, and have the following steps:

Step 1. is selected the diamond synthesis monocrystalline of 0.05ct～10ct, density: 3.515, and hardness: HV7000～10000.

The cutting method that step 2. adopts natural jewellery to bore, the natural jewellery that cut out shown in Fig. 1 a or Fig. 1 b or Fig. 2 a or Fig. 2 b or Fig. 3 a or Fig. 3 b or Fig. 4 a or Fig. 4 b or Fig. 5 a or Fig. 5 b or Fig. 6 a or Fig. 6 b bore.

Claims

1, a kind of jewel color diamond processing method is characterized in that comprising that step is as follows:

2, a kind of jewel color diamond processing method according to claim 1 is characterized in that adopting graphite powder: touch coal 7:3, select synthetic big the monocrystalline of 1773 ℃ of temperature and pressure 6.3GPa.

3, a kind of jewel color diamond processing method according to claim 1 is characterized in that making artificial jewel color diamond structure and is round, heart type, bateau type, egg shape, western pears type or emerald type.
