Physical properties
Mohs hardness: 10, Color: Colorless/White, Luster: Adamantine, Crystal Structure: Cubic, Specific Gravity: 3.52
Formation & geological history
Formed under high pressure and temperature in the Earth's mantle (150-250 km deep), brought to surface via kimberlite pipes. Geological age often ranges from 1 to 3.5 billion years.
Uses & applications
Primary use in high-end jewelry (rings, pendants) and industrial applications for cutting, grinding, and drilling due to extreme hardness.
Geological facts
Diamonds are the hardest known natural material on Earth. The name comes from the Greek word 'adamas', meaning unbreakable.
Field identification & locations
Identify by extreme hardness (can scratch all other minerals), high refractive index, and thermal conductivity. Commonly found in South Africa, Russia, Canada, and Botswana.
