Emerald History

The oldest emeralds are about 2.97 billion years old.The first known emeralds were mined in Egypt around 1500 BC. One of Cleopatra's favorite stones was emerald, and her passion for the stone was well documented. Emeralds were discovered in South America in the 16th century by the Spanish. They were used by the Incas well before this discovery. The Spanish traded emeralds across Europe and Asia for precious metals, which opened up the emerald trade to the rest of the world. Emeralds were first discovered in North America in the Yukon Territory in 1997, though large emerald deposits in the United States and further north are very rare. Synthetic sapphire and ruby were created in 1907, but synthetic emeralds were not created until 1935 when American chemist Carroll Chatham successfully grew his first 1-carat Chatham emerald. This stone is now on display at the Smithsonian Institute.

    • Emeralds were thought to guard against memory loss and enhance intuition. 
    • The soft, calming color of the emerald helped early lapidaries rest their eyes after an extended period of concentration. Today, emerald is still thought to relax and relieve eye strain. 
    • Top-quality emeralds can be worth more than diamonds on a per-carat basis.
    • Color, clarity, cut, and carat weight are four factors used to determine the value of an emerald. The most important of these four is color. The best color is vivid green or blueish-green with even saturation and no color zoning. 
    • Valuable, high-quality emeralds are very transparent and aren't too dark or too light. Green beryl that is too light in color may not even be considered emerald by some gemologists.
