Physical properties

Hardness: 7.5-8 Mohs; Color: Deep green to bluish-green; Luster: Vitreous to greasy; Crystal Structure: Hexagonal; Cleavage: Poor/Indistinct; Specific Gravity: 2.67-2.78

Formation & geological history

Formed in pegmatites or hydrothermal veins where beryllium-rich fluids interact with chromium-rich host rocks. This specific specimen appears to be raw emerald crystal embedded in a dark schist or mica-rich matrix.

Uses & applications

Primarily used as a gemstone for jewelry (once cut and polished) and highly valued by mineral collectors in its raw natural state.

Geological facts

Emeralds are the rarest of all gemstones; high-quality emeralds can be worth more than diamonds of the same weight. The green color is specifically caused by trace amounts of chromium or sometimes vanadium.

Field identification & locations

Identify by its characteristic hexagonal crystal habit and distinct green color against a darker host rock. Generally found in Colombia, Brazil, Zambia, and Russia. Collectors value specimens with high transparency and deep green color.
