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.
