Colombia

Colombia accounts for approximately 70-90% of the international emerald market. Geologically speaking, Colombian emeralds are said to be the purest emeralds in the world because the deposits are the only ones on earth found in sedimentary host rock, rather than in igneous rock. Typically, emeralds contain various inclusions that are visible to the unaided eye which can affect the durability, integrity and beauty of the gemstone. Therefore, top quality Colombian emeralds of fine, transparent material are highly sought after today. Emeralds with minor, insignificant or no oil treatment are very rare.
