Physical properties
Hardness: 10 (Mohs scale), Color: Colorless (in this specimen), Luster: Adamantine, Crystal structure: Cubic, Cleavage: Octahedral, Specific gravity: 3.52
Formation & geological history
Formed under high-pressure, high-temperature conditions in the Earth's mantle, approximately 100 miles below the surface, and brought to the surface by kimberlite pipe eruptions.
Uses & applications
Predominantly used in jewelry as a gemstone and in various industrial applications for cutting, grinding, and drilling due to its extreme hardness.
Geological facts
Diamonds are the hardest known natural material on Earth and can be over 3 billion years old. The name comes from the Greek word 'adamas', meaning invincible.
Field identification & locations
Identification includes testing for high thermal conductivity and hardness. Found in locations like Russia, Botswana, Canada, and South Africa. For faceted gems, look for 'fire' (dispersion) and sharp facet edges.
