In natural diamond the colour is related to a lattice imperfection. This can be mimicked in synthetic or treated diamond by a variety of treatments including annealing, heating or irradiating.

Synthetic brown diamond is created by compressing graphite under extreme pressure and heat to above 1500 Celsius. The treatments were perfected in several laboratories in Russia, United States and China.
