Zircon, a naturally occurring gemstone, has colorless, yellow, orange, red, blue, brown and green varieties. Zircon, by it's name, is sometimes confused with cubic zirconia ("CZ"), which is synthetic. In addition, both have been used as diamond substitutes. Zircon has a high refractive index which is responsible for it's diamond like appearance. Zircon can be distinguished from diamond by it's double refraction and by wear and tear of it's edges, as compared to diamond which is very much harder.
Green and brown colors of zircon are not enhanced. Yellow zircon is rarely heat treated to improve color. Blue, red and colorless are always heat treated brownish crystals to produce these colors.
