2015-2-24 · lue irradiated VD diamond The color of irradiated CVD-grown diamonds sub-mitted to the authors varied from fancy to fancy deep blue, with no gray secondary hue. The size of the round brilliant cut stones varied between 0.10 and 0.35ct, and the stones were relatively free of inclusions (VVS-VS). Blue stones were inert to both short-wave and long
The natural diamond, however, did have a slightly better color and clarity (G-IF compared to H-VVS 2). The clarity grade of the laboratory-grown diamond (VVS 2) was set by two types of inclusions: pinpoints and needles. Further analysis of the laboratory-grown diamond was performed using advanced spectroscopic techniques.
First of all our Labgrown Diamonds are real Diamonds and not Synthetic because They are made of same Carbon as a Natural mined Diamond. The Chemical, Physical and Structural properties are Identical. Our Diamonds are directly made in the Lab in a safe environment with no harm done to any Human or other Natural Habitat. No Deforestation.

2016-7-25 · The growth chamber is heated to 1300-1600 °C with pressures above 870,000 pounds per square inch. The molten metal dissolves the high purity carbon source. 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.

2012-6-1 · Viewing in crossed polarizers also distinguishes CVD from HPHT synthetics, which tend to display extremely low levels of strain (right). Shown in these photos are a 0.53 ct G-color CVD synthetic diamond (left), a 2.51 ct H-color CVD synthetic (center) and a 0.46 ct D-color HPHT synthetic .
HPHT processes produce yellow and orange diamonds that can be quite large (0.5 to 3 carats). Another way to recognize a synthetic diamond is that it has very specific impurities which are different from the ones found in nature. Indeed, even the most perfect natural color diamonds have some minor blemishes invisible to the eye.
