Physical properties

Hardness: 10 Mohs scale; Color: Colorless to faint yellow; Luster: Adamantine (brilliant); Crystal Structure: Isometric-Hexoctahedral; Specific Gravity: 3.52.

Formation & geological history

Formed at high temperatures and pressures at depths of 140 to 190 kilometers in the Earth's mantle over billions of years, brought to the surface by kimberlite eruptions.

Uses & applications

Predominantly used in jewelry as a gemstone and in industry for cutting, grinding, and drilling tools due to its extreme hardness.

Geological facts

Diamonds are the hardest known natural material. Most natural diamonds are between 1 billion and 3.5 billion years old.

Field identification & locations

Identify by its ability to scratch all other minerals, high thermal conductivity, and intense fire (dispersion). Faceted stones require professional equipment like a loupe or diamond tester for definitive ID.
