Physical properties
Hardness: 8-8.5 (CZ) or 10 (Diamond). Color: Colorless (typically). Luster: Adamantine. Crystal Structure: Cubic.
Formation & geological history
CZ is a synthesized material. Diamonds are formed deep in the Earth's mantle under high pressure and temperature.
Uses & applications
Primarily used in jewelry as a gemstone.
Geological facts
CZ is the most common diamond simulant due to its low cost, durability, and close visual likeness to diamond.
Field identification & locations
Can be identified by its flawless appearance and dispersion (fire) which is higher than a diamond's in the case of CZ. Look for wear on facet edges for CZ.
