These lovely pendants are not crystal - very high quality glass. There are 3 available and each offer is for one pendant. I photographed them together so you could see just how the light plays on them. They are approx. 30 mm in size. I do combine so please look at my other listings. I ship nearly everywhere too - just ask for a quote. All jewelry items may be returned for any reason - if you're not happy then I'm not either. You're responsible for all costs to return the item. Once I receive it in new condition I'll cheerfully refund your original purchase price and your original shipping. Thanks for looking!
