Welcome to Hydray, buy HPHT/CVD laboratory grown diamonds
2021-11-2 · Blue lab grown diamonds: When the carbon transformed into a lab diamond had traces of boron in it, the diamond is pale blue in color. Pink lab grown diamonds: It is speculated that the variations in the pressure levels on parts of the carbon may vary the molecular bonds in them to give out a beautiful pale pink hue and at times, a pale red ...
2021-11-26 · Lab grown diamond are produced in an artificial process. Now we have the technology to grow diamonds under the environment of HPHT or CVD. These kinds of synthetic diamonds have the same optical, physical and chemical properties as natural diamonds.
2021-11-9 · Lab grown diamonds, whether grown in with the HPHT or CVD method, have some key advantages compared to mined diamonds. Because of the high cost of mining and rarity of an earth grown diamond, man made diamonds are almost 40% cheaper than a natural diamond. Lab grown diamonds also come from a transparent supply chain and can be more ecologically ...
2019-6-5 · Lab-Grown Diamonds – HPHT – CVD. ... In the middle of last century it became possible to generate small stones that were deployed in industrial processes such as those used in the electronics field. These synthesized rocks, however, had no value within the jewelry market given their diminutive size and dull brown color and, according to an ...
A highly reliable detection device that screens for CVD & HPHT lab grown diamonds, and natural diamonds enabling a user to know about their nature of origin. It can screen large star, melee & pointer parcels and medium size rings, pendants, necklaces, earrings, within 10 seconds.
HPHT and CVD suitable size and price. Due to the growth principle, HPHT is suitable for growing smaller particles, and CVD is suitable for growing larger particles. The size is currently divided by one carat of the finished product. In the future, it may be increased to one and a half carats, or even two carats.

Yuda Crystal is one of the world's leading lab grown diamond companies, mainly active in fields: Gem quality lab grown rough (Including HPHT and CVD) diamonds manufacturing and wholesale, lab grown polish diamonds manufacturing and wholesale, Industrial grade HPHT and CVD lab grown diamonds manufacturing and wholesale.
2016-7-25 · Carbon atoms precipitate on a small diamond seed crystal, and a synthetic diamond begins to grow. The lab-grown crystal is then cut and polished by a diamond cutter. In greater detail, HPHT diamond growth takes place in a small capsule inside an apparatus capable of generating very high pressures.
DRC Techno | The global leader in Lab grown diamond (CVD & HPHT) diamond identification technology actively engages in R&D, designing and manufacturing solutions to safeguard the diamond manufacturing and jewelry industry worldwide
Lab Grown Diamonds is One Process Of Making Diamond In Lab. This means that a material is deposited from a gas onto a substrate and that chemical reactions are involved. HPHT stands for high pressure and high temperature. HPHT is a technique .
The CVD method was created in the 1980s, making it newer than the HPHT method. The CVD method imitates how diamonds form in interstellar gas clouds. The CVD method uses less pressure than the HPHT method as well as smaller machines. The CVD method places a diamond seed in a vacuum chamber. This chamber becomes filled with carbon rich gases and ...
