These are vintage glass rhinestones to use in your jewelry for repairs. The stones date from the 40's and 50's and have never been used. They come from all over including France, Germany, Czechoslovakia, etc. The stones are foiled back unless otherwise indicated. I have tried to describe them to the best of my ability so there is no confusion. Types of rhinestones range dramatically, so if you have any questions...please contact me. You can use these to repair brooches, earrings, necklaces, and bracelets. Many of the colors available here are no longer made and difficult to get a hold of. Due to the fact that these stones are vintage, a few might have minor defects...but this is normal for stones of this age. The Description is listed as = Color, Size, Cut, and the Quantity.
