It is one of the four precious gemstones in the world next to emerald, sapphire and diamonds, and the 3rd hardest gemstone. Ruby belongs to the Corundum family of gemstones. The red coloring comes from chromium in the stone. Mining rubies is done the same as it was centuries ago by panning in rivers and hand picking the stones. The largest sources of Ruby come from Thailand, Sri Lanka, Burma, Myanmar and Tanzania. These rubies have been dyed for a more uniform color.
