* Emeralds are green precious stones that are mined from the ground. They are the premier gems in the Beryl family of stone-rocks. Beryl has a hardness of 7.5–8 on the Mohs scale. For more than 4,000 years, emeralds have been among the most valuable of all jewels on earth. Colombia, located on the continent of South America, is the country that mines and produces the most emeralds for the global market. It is estimated that Colombia accounts for 70-90% of the world's emerald market. While commercial grade emeralds are quite plentiful, fine and extra fine quality emeralds are extremely rare. Colombian emeralds over 50ct can cost much more than diamonds with the same size. Colombian emeralds over 100ct can cost up to one million per carats. Depends of shape and quality. The most expensive know Colombian emerald is the ibis crown emerald with an estimated price of over 600 millions euro.
