Urdu or Indian name for Emerald is Panna.

Emeralds are usually treated by polymers or colorless oil in order to hide microfissures and to improve the stone appearance. Emerald prices highly depend on gem color and clarity; for this reason it is rather difficult to carry out the online valuating for emeralds. Unlike other beryl varieties clean pieces of emerald are extremely rare end expensive. We recommend referring to Gemval.com online appraisal as a value approximation within 15-20% accuracy.
