Physical properties

Hardness: 7.5-8.0 (Mohs); Color: Vivid green encased in dark grey/black host rock; Luster: Vitreous to greasy; Crystal Structure: Hexagonal; Specific Gravity: 2.67-2.78.

Formation & geological history

Formed in hydrothermal veins or pegmatites where beryllium-rich fluids interact with chromium or vanadium-bearing metamorphic rocks (schists) or igneous rocks.

Uses & applications

Primarily used in high-end jewelry (when faceted), lapidary arts, and as a highly sought-after mineral specimen for collectors.

Geological facts

Emerald is the most famous member of the beryl family. Unlike other gemstones, inclusions in emeralds are often called 'jardin' (French for garden) and are generally accepted as proof of authenticity.

Field identification & locations

Identified by its signature 'emerald green' color within a schist or calcite matrix. Commonly found in Colombia, Brazil, and Zambia. In the field, look for green hexagonal prisms embedded in host rock.
