A Beryl.
Emerald is the most precious of the Beryl family. Deep Green Beryl is called Emerald. It derives its beautiful color from the presence of chromium and vanadium. The intensity of color depends on the quantity of chromium. Due to rare occurrence of chromium and vanadium together, the emeralds are very scarce. |
|
Flawless Emeralds are rare so stones are often oiled to fill cracks, hide flaws and enhance color.The finest Emeralds are from Colombia followed by Africa, Brazil, Egypt and Pakistan. |
