Physical properties

Hardness: 10 (Mohs scale); Color: Colorless to grayish-white; Luster: Adamantine to brilliant; Crystal Structure: Isometric-hexoctahedral; Specific Gravity: 3.51

Formation & geological history

Formed under extreme pressure and high temperature in the Earth's mantle, brought to the surface via kimberlite pipes or found in secondary alluvial deposits. This specimen displays a 'druzy' or micro-crystalline cluster formation.

Uses & applications

Primarily used in fine jewelry (rings, earrings), as well as industrial abrasives and precision cutting tools due to its unparalleled hardness.

Geological facts

Diamond is the hardest natural substance known to man. The term 'druzy' refers to a coating of fine crystals on a rock surface, which in the case of diamonds, creates a unique glittering effect.

Field identification & locations

Identified by its incredible hardness and brilliant light refraction. Commonly found in South Africa, Russia, and Canada. Collectors look for even coverage and clarity in the micro-crystals.
