Physical properties
Hardness: 10 Mohs; Color: Colorless to faint yellow/brown; Luster: Adamantine; Crystal structure: Cubic; Specific gravity: 3.52.
Formation & geological history
Formed at high pressure and temperature in the Earth's mantle 1-3 billion years ago; brought to the surface by kimberlite eruptions.
Uses & applications
Primarily used in high-end jewelry and industrial applications for cutting, grinding, and drilling due to extreme hardness.
Geological facts
Diamond is the hardest naturally occurring substance known. The name comes from the Greek word 'adamas', meaning unbreakable.
Field identification & locations
Identified by its high refractive index, heat conductivity, and ability to scratch any other material. Found in kimberlite pipes or alluvial deposits.
