For millennia, emeralds have been one of the most admired and sought after gemstones in the world. Though they adorned Egyptian pharaohs and Roman emperors, emeralds achieved an exalted status when they returned to Europe in the 16thCentury on the boats of the Spanish Conquistadors from what is now South America. Since that time, emeralds have maintained their status as an exalted gem.

 Though mined all around the world, the finest emeralds come from Colombia, specifically from the Muzo mining area. With a rich, vibrant slightly bluish-green hue, the El Dorado emerald, graded as of Classic Colombian origin by the American Gemological Laboratories, an origin corroborated by the Gemological Institute of America and the Gubelin Gemlab, is a prime example of the finest emerald material.

 In addition to its exceptional color, the El Dorado emerald is unenhanced. Since they were first discovered, emeralds have been treated with oils and resins to minimize the appearance of naturally occurring inclusions. Any emeralds that have not been treated are scarce; those that are as inclusion-free as the El Dorado are exceedingly rare.

 An emerald that combines such extraordinary size, color and clarity, without any kind of enhancement is truly a special stone.
