Lab Grown Diamonds are not imitations of a diamond-like Cubic Zirconia (CZ) or Moissanite. Having the same physical and chemical properties as a Natural Diamond, Lab Grown Diamonds are only different in their growth processes
While Natural Diamonds are grown under the surface of the Earth in natural conditions, Lab Grown Diamonds- as the name suggests, are produced in a Lab using proprietary technology that has made it possible to imitate the same temperature and pressure conditions as under the Earth’s surface.
At Naam, we grow both- HPHT & CVD Lab Grown Diamonds. A key differentiator between HPHT and CVD diamonds is the morphology, i.e., the growth process.
While HPHT diamonds grow in a cuboctahedron shape, meaning they have fourteen growth directions, CVD diamonds grow cubic in just one growth direction.
On the other hand, natural diamonds grow like octahedrons with eight growth directions. Growth patterns are the primary way to identify mined and synthetic diamonds apart.
While the HPHT technology has been around since the 1950s- used only for industrial purposes until recently, CVD is a newer technology.
Both forms of Lab Grown Diamonds are cleaned, cut, polished, and graded by renowned laboratories in the same way as Natural Diamonds. There is no known benefit of using one or the other type of Lab Grown Diamond. Both types can be optimized to their leverages during cutting and polishing to produce the same beautiful results.
