Physical properties
Hardness: 10 (Mohs scale); Color: Adamantine luster, colorless/white in this setting; Crystal structure: Isometric (cubic); Specific gravity: 3.51
Formation & geological history
Formed deep within the Earth's mantle under intense heat and pressure over billions of years, then carried to the surface by explosive volcanic eruptions called kimberlite pipes.
Uses & applications
Predominantly used in jewelry (engagement rings, necklaces) due to its brilliance and durability; also used in industrial cutting, grinding, and drilling tools.
Geological facts
Diamond is the hardest naturally occurring substance on Earth. While they are famous as gemstones, 80% of all diamonds mined are used for industrial purposes.
Field identification & locations
Identify in the field by checking for high refractive index (brilliance/fire) and its ability to scratch glass and every other mineral; typically found in pipe deposits or alluvial gravels.
