Synthetic diamond (also referred to as laboratory-grown diamond, laboratory-created diamond, or cultured diamond) is a diamond made of the same material as natural diamonds: pure carbon, crystallized in an isotropic 3D form. Synthetic diamond are different from both natural diamond, which is created by geological processes, and imitation diamond, which is made of non-diamond material. Records of attempted diamond synthesis date back to the turn of the twentieth century. Numerous scie

How diamonds are made? Heart In Diamond

The typical CVD-diamond creation process goes something like this: A diamond seed (which is a tiny piece of diamond with a repeating pattern of carbon atoms like all diamonds have) is placed inside a microwave plasma oven. Natural gas is zapped into a plasma of carbon which sticks to each diamond seed, thus building a diamond one atom at a time.

CVD-Grown Synthetic Diamonds, Part 1: History

2013-04-30· To produce a gem-quality synthetic diamond, a diamond seed crystal (natural, HPHT, or CVD in origin) is introduced into the gas mixture, at an elevated temperature of 900 to 1200°C. The activated carbon-hydrogen species travels across the surface of the diamond seed until it finds an available carbon atom, and then attaches itself to this seed atom. The seeded growth is now one
