Lab Grown Diamond Education
CONGRATULATIONS on your purchase of a Lab Grown Diamond! Two methods are utilized to create lab grown diamonds: CVD (Chemical Vapor Deposition) & HPHT (High Pressure High Temperature).
The CVD method grows the diamond from a "seed” in a vacuum chamber using carbon rich gas heated to nearly 1,500 degrees. Heat turns the gas into plasma, creating carbon particles that attach onto the seed, which grows the diamond. The CVD process produces Type IIA diamonds, the most chemically pure diamonds found in nature.
The HPHT method produces Type IIB diamonds which may have a light blue hue due to the presence of nitrogen during the formation process. Tremendous pressure and heat combine to produce HPHT diamonds which may test as Moissanite but are, in fact, genuine diamonds.
You'll be unable to tell the difference between a CVD and HPHT diamond with the naked eye. Both methods create beautiful, sparkling diamonds that are optically, chemically, and physically identical to earth-grown diamonds.
