Physical properties
Hardness: 10 (Mohs scale), Color: Colorless (as shown), Luster: Adamantine, Crystal Structure: Isometric-Hexoctahedral, Cleavage: Octahedral, Specific Gravity: 3.52
Formation & geological history
Formed at high pressure and temperature in the Earth's mantle (140-190km deep) and brought to the surface by kimberlite eruptions. Most natural diamonds are 1 to 3.5 billion years old.
Uses & applications
Predominantly used in jewelry (rings, necklaces) and for industrial cutting, grinding, and drilling applications due to extreme hardness.
Geological facts
Diamond is the hardest natural substance known on Earth. The name comes from the Greek word 'adamas', meaning unbreakable or invincible.
Field identification & locations
Identify by its brilliance, ability to scratch sapphire, and high thermal conductivity. Commonly found in kimberlite pipes or alluvial deposits in Africa, Russia, Canada, and Australia.
