Physical properties
Hardness: 10 (Mohs scale), Color: Colorless, Luster: Adamantine, Crystal structure: Cubic, Cleavage: Perfect octahedral, Specific gravity: 3.52
Formation & geological history
Formed deep within the Earth's mantle under extreme high temperature and pressure, brought to the surface by deep-source volcanic eruptions (kimberlites and lamproites).
Uses & applications
Primarily used in jewelry as a gemstone, but also used extensively in industry for cutting, drilling, and grinding tools due to its extreme hardness.
Geological facts
The hardest known natural material on Earth. The name 'diamond' is derived from the ancient Greek word 'adamas', meaning 'unbreakable' or 'invincible'.
Field identification & locations
Identified by its extreme hardness, brilliant adamantine luster, and specific gravity. Often found in kimberlite pipes or alluvial deposits.
