Another factor that affects a diamonds's apparent color is the color of the mounting itself. Yellow gold makes slight amounts of yellow in a diamond less obvious, while white metal mountings make the color in yellow diamonds more apparent.
Synthetic diamonds of various colors grown by the high-pressure high-temperature technique. Synthetic diamond (also known as cultured diamond or cultivated diamond) is diamond produced in an artificial process, as opposed to natural diamonds, which are created by geological processes.or economic reasons, the growth of most synthetic diamonds is terminated when they reach a mass of 1 carat (200 mg) to 1.5 carats (300 mg). In the 1950s, research started in the Soviet Union and the US on the growth of diamond by pyrolysis of hydrocarbon gases at the relatively low temperature of 800 Â°C.
