Physical properties
Hardness: 10 (Mohs scale), Color: Colorless (as shown), Luster: Adamantine, Crystal Structure: Isometric (cubic), Cleavage: Perfect 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 eruptions.
Uses & applications
Primarily used in high-end jewelry (engagement rings, necklaces) and for industrial purposes such as cutting, grinding, and drilling due to its extreme hardness.
Geological facts
Diamonds are the hardest known natural substance. They are composed of a single element: carbon. Most natural diamonds are between 1 billion and 3.5 billion years old.
Field identification & locations
Identify by its brilliance, ability to scratch any other material, and heat conductivity. Commonly found in kimberlite pipes or alluvial deposits in locations like South Africa, Russia, and Canada.
