Emerald is the green variety of beryl. It is the most well known and valuable of the green gemstones. Its beautiful green colour together with its durability and rareness makes it one of the most expensive gemstones. Deep green is the most sought after colour. In general, it applies that the bleaker the colour, the lesser the value of the gemstone. Very pale green beryl is not called ‘emerald’ but green beryl. Apart from emerald, beryl can be found in other important gemstone varieties such as blue aquamarine, pink morganite and green-yellow heliodor/golden beryl. Goshenite is white/colourless.
Flawless emerald is very rare and has a high value. Some prefer gemstones with small faults rather than flawless as it is a sign of authenticity. Colombian emerald has traditionally held the highest quality and best colour but sources in Zambia are also producing deep green emerald of high quality. Despite its hardness, emerald is a brittle gemstone. Hard blows or temperature fluctuations can cause internal fractures. Emeralds that have been treated to hide internal flaws should never be cleaned with ultra sound. Neither should they be cleaned with regular soap or detergent. This can cause oil treatment to be removed causing the flaws to become visible.
