Ruby Gemstones or Manik Gemstones is a naturally occurring Gemstone, which is a variety of the mineral corundum (aluminum oxide). In terms of chemistry, Manik Gemstone is a mixture of Aluminum, Oxygen, Iron and Chromium.
The presence of chromium in the Ruby Stones structure gives its natural color ranging from pink to blood red. It is one of the four precious stones, leading to its increasing cost in the current market. The costs of Ruby Gemstones are primarily determined by color, the most expensive “red” being pigeon blood red. After color, the price matrix follows the cut and carat to determine the exact price.
