Physical properties
Hardness: 10 Mohs scale; Color: Colorless (in this specimen); Luster: Adamantine; Crystal Structure: Isometric-hexoctahedral; Specific Gravity: 3.52
Formation & geological history
Formed deep within the Earth's mantle under extreme pressure and temperature conditions, then transported to the surface by kimberlite eruptions. Geological ages can vary from 1 to 3.5 billion years.
Uses & applications
Primary use is in high-end jewelry and industrial applications for cutting, grinding, and drilling due to its extreme hardness.
Geological facts
Diamonds are the hardest natural substance on Earth. The name comes from the Greek word 'adamas', meaning unbreakable. Most natural diamonds were formed over a billion years ago.
Field identification & locations
Identified by its unmatched hardness, high refractive index (brilliance), and thermal conductivity. Commonly found in kimberlite pipes or alluvial deposits.
