What is HTHP Diamond

In the past, it was called Pegasus diamond and GE POL diamond. The reason why it is called GE Diamond is because 　The technology developed by GE in the United States is a new product exclusively sold by POL, a subsidiary of Israel's LKI, in 1999.

This technology is to process natural diamonds at high temperature and high pressure to enhance the color grade of the diamonds. In one move, it can be upgraded to 4-6 levels. However, not every diamond can be treated with this technology. It must be a type IIa diamond with a color of J or higher, without impurities, and with high clarity. During processing, the results cannot be predicted. In other words, it is not certain what level it can be promoted to.

At the same time, diamonds treated with HPHT may deepen or change in color to become a colored diamond.

In the past, only GE had such technology, and the processing method was listed as top secret. However, with the increase in the level of world technology, there are now some companies or institutions around the world that have the technology to process diamonds with high temperature and high pressure, which has become a new phenomenon threatening the world's natural diamond industry.
