At present, the circulation of less than 1 carat on the market is HPHT synthetic Diamonds, metal catalyst more clarity grade is not high, need to avoid too much, the advantage is good color, basically in H color above, according to the saturation of DE color, but most will have blue-green tone, the overall sense is not natural, easy to detect by the naked eye.

CVD loose diamond's advantage is blank is bigger, can cut big drill, in addition to the internal back to grow grain and residual graphite, relatively high overall clarity grade, defect is clear, color difference, difficult to have a F color above, basic on H color below, but the overall feel and natural drill is closer to the naked eye is extremely difficult to detect, enough amplification conditions, Growth stria characteristic is obvious. In contrast, I think CVD is better and more natural, and the price of future carats will be more affordable. As technology continues to improve, the color will also improve.
