Hardness: 7.5-8.0; Color: Vivid green encased in translucent yellow-white; Luster: Vitreous; Crystal structure: Hexagonal; Cleavage: Poor/Indistinct; Specific Gravity: 2.76.

Formation & geological history

Formed in hydrothermal veins or pegmatites where beryllium-rich fluids meet chromium-rich host rocks. These specimens appear to be small tumbled or water-worn green beryl crystals inside a quartz or calcite matrix.

Uses & applications

Commonly used for lapidary work, jewelry (when high quality), and as mineral specimens for metaphysical or geological collections.

Geological facts

Emeralds are the green variety of the mineral beryl. Their iconic green color comes from trace amounts of chromium and sometimes vanadium within the crystal structure.

Field identification & locations

Identify by looking for the distinct 'Emerald green' color within a host rock. High-quality emeralds are often found in Colombia, Brazil, and Zambia. These specific pieces show the characteristic 'jardin' or internal fractures.
