Cubic Zirconia (CZ), moissanite, etc., are diamond simulants as they look like diamonds, but have different chemical properties. Therefore, many experts argue that it is inappropriate to call simulated diamonds, 'diamonds'; they should be simply known as simulants. Simulated Diamonds - A Flashback.
A newer method of creating synthetic diamonds, called chemical vapor deposition or CVD, involves growth at high temperatures in a vacuum chamber. Hydrocarbon gases, such as methane, are introduced into the chamber and broken down by means of an energy source, such as microwave plasma, to release their carbon atoms. few companies sell CVD-grown synthetic diamonds in small quantities for jewelry purposes. Most CVD crystals are brownish or grayish, but if a tiny amount of nitrogen or boron is introduced into the chamber, yellow, pink-orange, or blue crystals can be created.
