About Ruby: Ruby is the birthstone for July and the 40th wedding anniversary stone. 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. Lab Grown Gemstones: A lab grown gem is a man-made material with essentially the same chemical composition, crystal structure and optical and physical properties as the natural gem material. Materials: Ruby lab grown gemstone 10x5mm marquise cut 925 sterling silver box chain and pendant setting If you have any questions just click "message seller" on our homepage.
