Physical properties
Hardness: 10 (Mohs), Color: Colorless (common) to various hues, Luster: Adamantine, Crystal Structure: Cubic/Isometric, Cleavage: Perfect octahedral, Specific Gravity: 3.52
Formation & geological history
Formed deep within the Earth's mantle under extreme pressure and high heat, then brought to the surface by volcanic eruptions of kimberlite and lamproite magma.
Uses & applications
Extensively used in high-end jewelry and industrial applications such as cutting, drilling, and grinding tools due to its unparalleled hardness.
Geological facts
Diamond is the hardest naturally occurring substance on Earth. Most natural diamonds are between 1 and 3.5 billion years old.
Field identification & locations
Identified by its high refractive index (brilliance) and hardness. Found in kimberlite pipes or alluvial deposits in locations like Russia, Botswana, and Canada.
