Physical properties

Hardness: 7.5-8.0 on Mohs scale; Color: Pale greenish-yellow; Luster: Vitreous to greasy; Crystal structure: Hexagonal; Cleavage: Imperfect/Poor; Specific Gravity: 2.63-2.90

Formation & geological history

Formed in granitic pegmatites and metamorphic hydrothermal veins where beryllium is present. Often found alongside quartz, feldspar, and mica.

Uses & applications

Main source of beryllium for aerospace and defense industries; high-quality specimens used as gemstones (Aquamarine/Heliodor/Emerald); crystal healing collecting.

Geological facts

Beryl is colorless when pure; the pale green/yellow tint in this specimen is caused by trace amounts of iron. It is highly resistant to chemical corrosion.

Field identification & locations

Identify in the field by its high hardness (scratches glass/quartz) and hexagonal cross-section. Commonly found in pegmatite districts like Brazil, Pakistan, and the Ural Mountains.
