Physical properties
Hardness: 10 (Mohs scale), Color: Colorless (in this specimen), Luster: Adamantine, Crystal structure: Isometric-Hexoctahedral, Cleavage: Perfect in four directions
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
Used primarily in fine jewelry (necklaces, rings, bracelets) and industrially as an abrasive or for cutting tools due to its extreme hardness.
Geological facts
Diamond is the hardest naturally occurring substance on Earth. Most natural diamonds are estimated to be between 1 billion and 3.5 billion years old.
Field identification & locations
Identify by its exceptional brilliance, fire (dispersion of light), and inability to be scratched by any other material. Commonly found in kimberlite pipes or alluvial deposits.
