1mm - 2mm DEF Color VS1-SI1 HPHT Lab Grown Melee Diamonds
Lab Grown Melee Diamonds Description
Lab-grown diamonds are diamonds grown in the laboratory using equipment that simulate the growth environment of natural diamonds. Both lab grown diamonds and natural diamonds are real diamonds. The main chemical components of lab grown diamonds and natural diamonds are carbon.
Lab grown diamonds is usually produced by chemical vapor deposition (CVD) or high pressure high temperature (HPHT) methods.
For a long time, people believed that diamonds could only be created under high pressure and high temperature conditions, imitating the formation of natural diamonds. This is called HPHT(high pressure and high temperature) method.

Lab Grown Melee Diamonds Introduction
Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Rough Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.
