Physical properties

Formation & geological history

Diamonds are formed deep within the Earth's mantle under extreme heat and pressure, typically 1 to 3 billion years ago. They are brought to the surface by deep-source volcanic eruptions. Cubic Zirconia is typically lab-created.

Uses & applications

Used extensively in jewelry due to its brilliance and durability. Industrial applications include cutting, grinding, and drilling tools.

Geological facts

Diamond is the hardest known natural material. Only a diamond can scratch another diamond.

Field identification & locations

Identify natural diamond by thermal conductivity, high refractive index, and specific gravity. Differentiating from simulants often requires gemological instruments.
