Emerald

a mineral that is a transparent variety of beryl tinged with an admixture of Crj03 to a deep grass-green color. Emeralds are found in crystals and their concretions, usually intergrown in micaceous rock, quartz, or feldspar. The crystals, measuring 2–5 cm by 0.5–2 cm, rarely larger, are fractured. The larger deposits are connected with zones of the contact alteration of amphibolites, magnesial schist, and serpentinites by granitic pegmatites. Emeralds are also found in quartz feldspar veins and in altered schistose-carbonate rocks. Deposits are rare and are mainly in the USSR (Urals), Republic of South Africa (Transvaal), and Colombia (Muzo). Emeralds are highly valued as gems; those that are large (more than 5 carats), flawless, and have a deep, rich color are considered to be more valuable than diamonds.

Synthetic emeralds (so-called igmeralds) are made, but their crystals are often fissured and no larger than 0.5 by 3 cm.
