CZ Stones – Marquise Cut – Arctic Blue (AG132)

CZ (Cubic Zirconia) stones are lab-grown gemstones.

Cubic zirconia (CZ) is the cubic crystalline form of zirconium dioxide (ZrO₂). The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO₄). It is sometimes erroneously called cubic zirconium.  (Wikipedia)

CZ’s are an inexpensive diamond alternative.

Firing these stones is not recommended.
