Jewelry, lapidary use, mineral collecting, and historical use as birthstones or talismans.

Geological facts

Emeralds are one of the 'Big Three' colored gemstones. Unlike many other gems, inclusions (known as the 'jardin' or garden) are often accepted and even used to prove natural origin.

Field identification & locations

Identify by the characteristic 'emerald green' hue against a lighter quartz or darker schist matrix. Commonly found in Colombia, Brazil, and Zambia. Collectors look for high saturation of green and transparency of the crystal.
