Emerald is the green variety of the mineral beryl and is one of the world’s best-known gemstones. The Colombian deposits of Muzo, Coscuez, Chivor and Gachalá are particularly famous; their deposits are characterized by hydrothermal mineralization in sedimentary rocks.
In this category, you will find emerald specimens with precise locality information, including pieces from classic Colombian mining districts. Depending on the locality and crystal development, emerald crystals may occur individually, in matrix, or together with associated minerals such as calcite, pyrite or quartz.
For emerald specimens, in addition to color and crystal form, reliable locality information, condition and possible treatments are especially important. The specimens offered here are documented with dimensions, weight, photographs and the most precise provenance information possible.
