Emerald
		Emerald is from the beryl family. It is green because of the presence of the element chromium. Emeralds naturally occur in nature and it is common to oil them to improve their clarity and this is a general accepted practice. The untreated ones are very rare and command a premium. Emeralds originate from various origins such as Colombia, Brazil, Zambia, etc. We are exclusive marketing partners of Gemfields so that we can supply consistent quality of Zambian emerald for your needs. We carry emerald in calibrated sizes in several shapes such as rounds, ovals, marquise, etc in various sizes. For more information on the sizes we usually keep in calibrated sizes, please click here.
