Mined over 4000 years ago in Egypt, during the reign of Pharaoh Sesostris III, this precious stone has been held in high regard since antiquity. Emerald is a variety of the Beryl family (a mineral group that includes Aquamarine, Morganite and Heliodor) and receives its colouring from traces of chromium and vanadium within its crystal structure.

Some Emeralds have an almost velvety appearance, and are one of only a few gems where inclusions are not only tolerated, but considered to be part of the gem’s character. As a general rule, a vivid Emerald, full of inclusions, will normally demand a higher price than a flawless one paler in colour.
Most Emeralds on the market are treated at the time of cutting with wax, oils or resins. Unlike nearly all other gemstones, most treatments applied to Emeralds are not permanent and to maintain the gem’s unrivalled beauty, need re- applying every 5 to 10 years.
Stones displaying bluish overtones are sourced from Colombia and are considered by connoisseurs to be some of the world’s finest. Unfortunately, these Emeralds are becoming increasingly rarer as mine owners are having to dig deeper and deeper - and with very little success. Other sources of Emeralds include Brazil, Pakistan, Siberia, Zambia, and Zimbabwe.
