Original Ruby gemstone or Chuni gemstone is a variety of mineral corundum. The word ruby comes from the Latin word ruber or rubrum which means red. They are obtained directly from nature, below the earth's surface. They feature a vivid red color with a slightish purple tint.

The natural ruby stone are formed below the earth under extreme heat and pressure. Chromium is the trace element that gives the captivating red hue to the stone.
