Lead glass treated rubies/blue sapphires has become so abundant in the market, I am wondering whether the treated stones should be called corundum, really. Today treated stones have become perfect tools for scams because many people are unaware that the lead-glass treatment exists + the materials are sold at low prices. If you are doubtful always consult a reputed gem testing laboratory.
