Physical properties
Hardness: 10 (Mohs scale), Color: Colorless/Yellow/Brown, Luster: Adamantine, Crystal Structure: Cubic, Cleavage: Octahedral, Specific Gravity: 3.52
Formation & geological history
Formed at high pressures and temperatures in Earth's mantle, approximately 100-150 miles underground, and brought to the surface by kimberlite eruptions.
Uses & applications
Diamond is used in high-end jewelry (solitaires, pavé settings), and industrially for cutting, drilling, and grinding tools due to its extreme hardness.
Geological facts
Diamond is the hardest naturally occurring substance on Earth. It is also an excellent thermal conductor and is formed from pure carbon.
Field identification & locations
Identified by its high index of refraction (sparkle), hardness (scratches all other minerals), and thermal conductivity. Commonly found in secondary alluvial deposits or primary kimberlite pipes.
