Emerald

Emerald is a precious gemstone known for its rich green color and its historical significance. It belongs to the beryl mineral family and gets its distinctive green color from traces of chromium and vanadium in its crystal structure

The value of an emerald is influenced by factors such as color, clarity, size, origin, and overall quality. The most valuable emeralds are those with an intense, vivid green color, minimal inclusions visible to the naked eye, and a good overall appearance.
