Physical properties
Hardness (10 Mohs scale), Colorless/White (most common), Adamantine luster, Isometric/Cubic crystal system, Octahedral cleavage, Specific gravity 3.52.
Formation & geological history
Formed under high-pressure, high-temperature conditions in Earth's mantle, typically at depths of 150-250km, and transported to the surface by kimberlite or lamproite volcanic eruptions.
Uses & applications
Primary use in high-end jewelry and as industrial abrasives for cutting, drilling, and grinding due to its extreme hardness.
Geological facts
Diamond is the only gemstone made of a single element: Carbon. The Hope Diamond is one of the most famous examples globally, known for its rare blue color and alleged curse.
Field identification & locations
Identify by its extreme hardness (cannot be scratched by any other mineral) and high thermal conductivity. Commonly found in secondary alluvial deposits (rivers/beaches) or primary kimberlite pipes.
