Emerald, or Panna Ratna, is a green-colored precious gemstone of the Beryl mineral group. The cost of an Emerald gemstone in India or anywhere in the world mainly depends on two factors. One is technical factors, such as cut, color, clarity, carat weight, and place of origin while the other one is universal demand and supply chain. The per-carat Emerald Stone price starts from Rs. 5,000 and reached up to Rs. 5,00,000 or more on the basis of quality factors.
