Cubic Zirconia is called a “Simulant.” It is a man made “stand-in” for a natural diamond. Cubic Zirconia, when compared to a natural diamond, has different chemical and physical properties but its similarities in appearance are unmistakable.
Cubic Zirconia is a crystal form of "zirconium oxide." It is hard, usually colorless and visually unblemished, and may be synthesized in a variety of different hues.
The characteristics that distinguish Cubic Zirconia from a diamond are:
Commercial production of Cubic Zirconia (CZ) began in 1976 and due to its low cost, durability, and close visual resemblance to natural diamonds, it is to this day its chief contender.
Moissanite (first discovered by Henri Moissan), is a synthetic gemstone and serves as an alternative to cubic zirconia. It is a durable and low cost simulant that is composed of the crystal "carbide." In comparison to cubic zirconia, Moissanite displays a somewhat more sparkle.
