What's the HPHT diamond?

Specifically, the growth process is to put high-purity graphite as a carbon source in the high-temperature zone of the top press growth chamber, and place natural or lab created diamond seeds in the low-temperature zone. Driven by a certain temperature gradient, carbon will diffuse from a high concentration area at a high temperature to a low concentration area at a low temperature,and crystallize when the seed crystal is supersaturated at a low temperature. Through the seed crystal, it will "germinate and grow a little bit like a seed." Large". So this method is also called the seed temperature.

What is a lab grown diamond called?
Man-made diamonds, also known as synthetic diamonds or lab created diamonds, are grown in a highly controlled laboratory environment, using advanced technology to replicate the conditions under which diamonds are formed naturally under the crust. There are two types of cultivating diamonds,one is high temperature and high pressure technology, the other is cvd technology, but the diamonds produced by the two technologies are real diamonds. They are the same as natural diamonds mined from the ground. They are called real diamond.
