Cubic Zirconia
Popular, abundant and inexpensive, Cubic Zirconia (CZ) is make from zirconium oxide, and has been around since the late 1970s.
High quality CZ’s are actually a very good diamond simulant. It has a hardness of 8.5 on the Mohs Scale. CZ is virtually flawless and often out-shines all but the most expensive diamonds in clarity and brilliance. Because CZ is widely available, it is one of today’s most popular stones for creating attractive-yet-inexpensive, diamond-look-alike jewelry. Cubic zirconia is used in rings, pendants, bracelets, earrings, other pieces where you might find diamonds.
