Physical properties

Hardness: 7.5-8.0 (Mohs); Color: Deep green to bluish-green; Luster: Vitreous; Crystal system: Hexagonal; Specific gravity: 2.67-2.78; Fracture: Conchoidal to uneven.

Formation & geological history

Formed in hydrothermal veins or pegmatites where beryllium is present in magmatic fluids reacting with chromium or vanadium in surrounding metamorphic rocks like schist or shale.

Uses & applications

Primarily used as a gemstone in high-end jewelry; raw specimens are popular for mineral collectors and metaphysical practitioners.

Geological facts

The green color of emerald is caused by trace amounts of chromium or vanadium. Flawless emeralds are extremely rare, and most contain inclusions known as 'jardin' (garden) that prove their natural origin.

Field identification & locations

Identify by its distinct hexagonal crystal habit and vibrant green color against a darker host rock (matrix). Commonly found in Colombia, Brazil, Russia, and Zambia. Collectors look for clarity and color saturation.
