Physical properties
Hardness: 10 (Mohs scale), Color: Colorless/Yellow, Luster: Adamantine, Crystal Structure: Cubic/Isometric, Cleavage: Octahedral (perfect), Specific Gravity: 3.52
Formation & geological history
Formed under extreme high-pressure and high-temperature conditions in the Earth's mantle, approximately 100 miles below the surface, and brought to the surface through volcanic pipes called Kimberlites.
Uses & applications
Primary use in high-end jewelry (rings, earrings, necklaces) and industrial applications such as cutting, grinding, and drilling due to extreme hardness.
Geological facts
Diamonds are the hardest known natural material on Earth. Most natural diamonds are between 1 billion and 3.5 billion years old.
Field identification & locations
Identification in the field usually occurs in kimberlite pipes or alluvial deposits. Identification involves testing for high thermal conductivity and extreme hardness that can scratch any other mineral.
