Emerald
Emerald is the most precious stone in the beryl group. By definition, emerald is any medium to dark green beryl colored by chromium. The historical green color of emerald is unparalleled in the world of gemstones and it is considered as one of the most 'precious four' of all gemstones, which also includes sapphire, ruby and diamond. Although emeralds are one of the most valuable gemstones available today, most are very heavily included, rendering their resistance to breakage as generally poor.
Although Colombia is the most famous source for 'deep green' emeralds, emerald deposits are mined from many locations around the world. Recent decades have seen emerald production increase as a result of newly discovered deposits in South America, Africa and across Europe. Today, Brazil and Zambia are among the leading producers of fine emeralds, following Colombia.
