Physical properties
Hardness: 7.5-8 on Mohs scale; Color: Blue-green to pale blue; Luster: Vitreous; Crystal Structure: Hexagonal (prismatic); Cleavage: Imperfect; Specific Gravity: 2.66-2.80
Formation & geological history
Formed in granitic pegmatites or hydrothermal veins where beryllium is present. Often associated with quartz, feldspar, and muscovite. Geological ages vary greatly depending on the deposit location
Uses & applications
Primarily used as a gemstone in jewelry due to its transparency and color. Highly valued by mineral collectors for its crystal habit
Geological facts
The name comes from the Latin 'aqua marina', meaning 'water of the sea'. It is the birthstone for March and is famous for its large, high-clarity crystals found in Brazil
Field identification & locations
Identify by its hexagonal prismatic shape, hardness (scratching quartz but being scratched by topaz), and blue-green hue. Commonly found in Brazil, Pakistan, and Madagascar
