A fancy coloured diamond will exhibit a distinct, attractive colour. They are available in an array of colours, tones and saturations.
Lab-grown diamonds are diamonds that are created in a laboratory setting using advanced technological processes that replicate the natural formation of diamonds. They have the same physical, chemical, and optical properties as natural diamonds.
HPHT diamond refers to diamond synthesized through high temperature and high pressure technology. It is formed by placing a carbon source, a catalyst (metal powder) and a diamond seed into a high-pressure container to simulate the environment deep in the mantle.
CVD diamond (Chemical Vapor Deposition) is carried out under relatively low pressure and temperature. It is formed by introducing carbon-containing gas into a vacuum environment and decomposing it into carbon atoms through microwaves or other means. The carbon atoms are deposited layer by layer on the surface of the diamond seed.
