Physical properties
Hardness: 10 (Mohs scale), Color: Colorless to faint yellow/brown, Luster: Adamantine, Crystal Structure: Cubic (Isometric), Cleavage: Perfect octahedral, Specific Gravity: 3.52
Formation & geological history
Formed under high-pressure, high-temperature conditions in the Earth's mantle, typically at depths of 150-200km, then brought to the surface by volcanic eruptions of kimberlite or lamproite pipes.
Uses & applications
Used primarily in jewelry as gemstones and in industrial applications for cutting, grinding, and drilling due to extreme hardness.
Geological facts
Diamonds are the hardest known natural substance. The oldest diamonds are estimated to be around 3.3 billion years old.
Field identification & locations
Identify by its hardness (will scratch any other material) and adamantine luster. Found in kimberlite pipes or alluvial deposits. Collectors look for unique crystal shapes like octahedrons.
