Our ruby y necklace is handcrafted in a minimal lariat style with genuine ruby and opal gemstones wrapped onto our dainty gold filled cable chain. Ruby stones are faceted heart briolettes with a deep red color perfect for holiday occasions. The opal stones have dancing color play and the drop slides freely along the chain. A great gift idea for someone with a July birthday. About Ruby: Ruby is the birthstone for July and the 40th wedding anniversary stone. It is one of the four precious stones 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 ruby stones have been dyed for a more uniform color.
