Physical properties

Formation & geological history

Forms in hydrothermal veins and metamorphic rocks where beryllium-rich fluids encounter chromium- or vanadium-bearing rocks. Emerald deposits range from ancient to geologically young, with major sources in Colombia, Zambia, and Brazil.

Uses & applications

Used in fine jewelry and as a collectible gemstone; lower-grade material may be cut into beads or decorative objects.

Geological facts

Emerald is the green variety of beryl, and its characteristic internal inclusions are traditionally called a jardin (“garden”).

Field identification & locations

Identify by its rich green color, hardness, and typical inclusions, but laboratory testing is needed to distinguish natural emerald from synthetic or other green stones. The image shows a tiny faceted green stone in jewelry; estimated value is roughly $10–$500+, depending heavily on identity, treatment, and quality.
