Physical properties
Hardness: 10 (Mohs scale), Color: Near-colorless/slight yellow tint, Luster: Adamantine, Crystal Structure: Cubic/Isometric, Cleavage: Perfect octahedral
Formation & geological history
Formed deep in the Earth's mantle under extreme pressure and high temperatures, then transported to the surface by kimberlite magma eruptions billions of years ago.
Uses & applications
Primarily used in jewelry (rings, earrings) due to brilliance and durability; industrial-grade diamonds are used for cutting, grinding, and drilling tools.
Geological facts
Diamonds are the hardest known natural substance. The specific brilliant cut seen here is designed to maximize light reflection through total internal reflection.
Field identification & locations
Identify in the field by high thermal conductivity and refractive index; common in kimberlite pipes or alluvial deposits in regions like South Africa, Russia, and Canada.
