Physical properties
Hardness: 10 (Mohs scale), Color: Colorless (D-grade), Luster: Adamantive, Crystal Structure: Isometric-Hexoctahedral, Cleavage: Perfect in four directions
Formation & geological history
Formed deep in the Earth's mantle under extreme pressure and temperature, typically billion of years old, transported to the surface via kimberlite volcanic eruptions.
Uses & applications
Primarily used in jewelry (engagement rings, necklaces), and industrially as an abrasive for cutting and drilling due to its supreme hardness.
Geological facts
Diamond is the hardest known natural substance. The specific cut shown appears to be a round brilliant cut, designed to maximize light return (brilliance and fire).
Field identification & locations
Identify by testing for thermal conductivity and hardness; synthetic moissanite or cubic zirconia are common look-alikes. Found globally in regions like Botswana, Russia, and Canada.
