Physical properties

Mohs hardness 10 (diamond) or 8.5 (CZ); brilliant adamantine luster; isometric crystal system; colorless and transparent with high dispersion.

Formation & geological history

Formed deep in Earth's mantle under extreme pressure and temperature, transported via kimberlite pipes; or synthetically crystallized in a lab.

Uses & applications

Predominantly used as accent stones ('melee') in fine jewelry, rings, and watches, as well as industrial cutting abrasives.

Geological facts

Diamond is the hardest known natural mineral on Earth, consisting solely of carbon atoms bonded in a tight crystal lattice.

Field identification & locations

Identify using a thermal/electrical conductivity gem tester or specific gravity test to distinguish real diamonds from cubic zirconia or glass simulants.
