Physical properties

Hardness: 7.5-8.0 (Mohs); Color: Green to bluish-green; Luster: Vitreous; Crystal system: Hexagonal; Cleavage: Poor/Indistinct; Specific Gravity: 2.7-2.8

Formation & geological history

Formed in metamorphic or hydrothermal environments where beryllium-rich fluids interact with chromium or vanadium-rich rocks (such as schist or mica). Many deposits range from 65 to 500 million years old depending on geography.

Uses & applications

Predominantly used as a gemstone in high-end jewelry. Rough specimens are highly sought after by mineral collectors for display.

Geological facts

Emerald is the birthstone for May. Unlike other gemstones, internal inclusions (called 'jardin') are generally accepted as part of the natural character of the stone and often prove its origin.

Field identification & locations

Identify by its distinct hexagonal crystal habit and vibrant green color against a darker host rock like mica-schist or white calcite. Common locations include Colombia, Brazil, Zambia, and Russia.
