This rare and unusually large, 12.11 carats, natural green emerald is in the emerald shape, in a brilliant/step cut, and is very eye clean. It is from the revered gemstone mines of Zambia and has been treated to enhance its clarity, a common trade practice. The loose Emerald is GIA certified and ready to be set into a regal jewelry setting, or kept as an investment. In ancient Egypt, Queen Cleopatra had emerald mines named after her, and the gemstones were considered a symbol of eternal life.
