Physical properties
Hardness: 10 (Mohs scale), Color: Colorless (as shown), Luster: Adamantine, Crystal structure: Isometric-hexoctahedral, Cleavage: Octahedral, Specific gravity: 3.52
Formation & geological history
Formed under high-pressure, high-temperature conditions in the Earth's mantle, typically at depths of 150-200 kilometers, and brought to the surface by kimberlite and lamproite volcanic eruptions.
Uses & applications
Primary use is in fine jewelry as gemstones. Industrial uses include cutting, grinding, and drilling tools due to its extreme hardness.
Geological facts
Diamond is the hardest naturally occurring substance known to man. It is composed of a single element: Carbon arranged in a rigid crystal lattice.
Field identification & locations
Field identification involves professional tools like loupes for checking inclusions and thermal/electrical conductivity testers. Look for high dispersion (fire) and sharp facet edges.
