Cubic Zirconia

Cubic zirconia also known as CZ is the cubic crystalline form of zirconium dioxide . Though much less expensive than diamonds, the brilliance and crystal clear properties of cubic zirconia make it one of today’s most popular stones for an inexpensive yet very attractive, diamond-comparable jewelry.

The man-made material is hard, optically flawless and usually colorless, however different techniques are used to produce them in a variety of different colors. It is not a mineral as it synthesized and should not be confused with zircon, which is a zirconium silicate. Cubic zirconia is softer than a Diamond – 10 on Mohs hardness scale – but still considered a hard gemstone coming in at  8.5 on the hardness scale.

Cubic zirconia is available in varying qualities and usually a five-tiered system of A (lowest grade) to AAAAA (highest grade) is used to designate cubic zirconia qualities.
