Raw Emerald
Emerald is a gemstone variety of the mineral beryl. The stone is colored green due to trace amounts of chromium and sometimes vanadium. Colombia is by far the world's largest producer of emeralds, constituting 50–95% of the world's production; we also find emerald mines in Brazil in the region of Bahia. The term “Raw Emerald” is not yet popular, but it consists of the premature raw formation of a beryl which is found in abundance within emerald mines and often discarded. The use of this stone in semi-precious jewelry designs is very popular in Brazil.
