Physical properties

Hardness: 10 (Mohs scale); Color: Pink; Luster: Adamantine; Crystal structure: Cubic (Isometric); Cleavage: Perfect octahedral; Specific gravity: 3.52

Formation & geological history

Formed under intense heat and pressure deep within the Earth's mantle, typically dating back 1 to 3.5 billion years. Pink color is believed to be caused by plastic deformation in the crystal lattice during its journey to the surface in kimberlite pipes.

Uses & applications

Primarily used in high-end jewelry and as a significant investment asset for collectors due to extreme rarity.

Geological facts

Pink diamonds are among the rarest gemstones in the world; for many years, the Argyle mine in Australia produced over 90% of the world's supply before its closure in 2020.

Field identification & locations

Identification requires professional gemological equipment to distinguish from pink sapphires or cubic zirconia; often found in kimberlite and lamproite pipes or alluvial deposits.
