I bought a 63.1 karat ruby. It has to be glass. When i received it I noticed that it turned the bag red. They must be just dyed it... What am I to think? I so upset I could throw up. Thinking I'm buying something nice and look what I got... They are a scam. Please if you are thinking about bidding on they item go to a legit site like ebay or take a look at amazon.
