Emerald In Matrix

Physical Properties

Hardness: 7.5-8 on Mohs scale; Color: Green to dark green; Luster: Vitreous; Crystal system: 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 or vanadium-bearing host rocks (often schist or limestone). Many deposits are hundreds of millions of years old.

Uses & Applications

Used primarily in jewelry as a precious gemstone. Lower quality specimens like this one are popular for mineral collecting, metaphysical use, or lapidary carving.

Geological Facts

Emerald is the green variety of Beryl. The green color is caused by trace amounts of chromium or vanadium. Flawless emeralds are extremely rare, and most contain inclusions known as the 'jardin' (garden).

Field Identification & Locations

Identify by its distinctive hexagonal crystal habit and characteristic 'emerald green' color. Commonly found in Colombia, Brazil, Zambia, and Ethiopia. Look for green hexagonal prisms embedded in dark schist or white quartz matrix.
