Zircon Information
Zircon should never, never, never be
confused with cubic zirconia (CZ). Zircon is a beautiful
natural gemstone that exhibits exceptional brilliance and a
diamond-like luster. Zircon comes in many colours and one of
the most popular is blue. The "Cambodian Blue" comes from a
unique material that is brownish in colour and when heated becomes a
wonderful saturated blue.

among zircons so mineralogists classify them into at leave two
types: low properties and high properties
