Rough Diamond HPHT From Chinese Manufacturer

Synthetic White Rough Diamond  for Processed into Naked Diamond

Diamond are formed in 125-400km below the earth surface where the atmospheric  pressure is over 50 thousand times than on the earch surface. As far as the grown condition, grown diamonds are similar to the diamonds growing inside the earth. Using high pressure and high temperature(HPHT), we have the capacity to produce grown diamonds, which have the same optical, phytical and chemical properities as a mined diamond. At the same time, the grown diamond fulfills paraments of all the major lab certifications in the world, like GIA and IGI, etc.
