Physical properties

Hardness: 9.0 on Mohs scale; Color: Pink; Luster: Vitreous/Adamantine; Crystal Structure: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture); Specific Gravity: 3.95-4.03

Formation & geological history

Formed in metamorphic rocks seperti marble or schist, and igneous rocks through high-pressure volcanic activity or cooling magma chambers. Commonly found in alluvial deposits. Geological age varies greatly by deposit.

Uses & applications

Predominantly used in high-end jewelry (earrings, rings, pendants) due to extreme durability and beauty; also used in industrial precision instruments.

Geological facts

Sapphire and Ruby are the same mineral family (corundum). Pink sapphires were once considered 'light rubies' until the late 20th century. Larger clear specimens are extremely rare.

Field identification & locations

Identify by extreme hardness (can scratch most other surfaces except diamond) and high density. Look for hexagonal crystal habits in raw form. Often found in Madagascar, Sri Lanka, and Myanmar.
