What is Emerald
Emerald is a variety of Beryl which has the Mohs hardness of 7.5 to 8. When Beryl contains chromium and vanadium, it appears in green rather than colorless, and only the ones in certain level of green with good clarity can be classified as Emerald. Most Emeralds are born with flaws and inclusions, specialists use jardin, which means garden in french, to describe this feature, these inclusions also reveal the forming environment and origin of an Emerald. Due to the flaws and inclusions, Emerald is very fragile, it breaks easily while cutting or wearing, therefore, people soak Emerald into colorless oil to strengthen it, Emerald gets firmer when oil fills the flaws. Oil treatment is accepted by countries, and the scale of the treatment is mentioned on certificates. Emerald in good quality which has fewer flaws does not need too much oil treatment, the price will be higher.

Later people discovered that gemstones with Emerald Cut has large facets that brings a big advantage for displaying the clarity and the color so now Emerald Cut is normally a preferred way of cutting on the kinds of gemstones with high clarity and elegant tone that does not show obvious scintillation, at the same time, thanks to technology development, Emerald can be cut into different shapes.
