Emerald

Emerald is one of the four precious stones.
It is a mineral and a variety of beryl.
Its green colour is caused by traces of chromium, vanadium and sometimes iron.
The word ’emerald’ comes from the Greek ‘smaragdus’, meaning ‘a green precious stone’.
Emerald is found primarily in deposits in Colombia and Zambia, but also in Afghanistan, Brazil, Pakistan, Russia and Zimbabwe.
