Ruby, or Manik Ratna, is a red-colored precious gemstone of the Corundum mineral group. The cost of a Ruby 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 Ruby Stone price starts from Rs. 2,000 to 10,000 or beyond depending upon the quality factors.
