These vintage stones were probably made in Western Germany. They are a translucent ruby red iris finish glass with a textured flower type pattern on top. At least I think it's a flower! They measure 15x7mm and have a silver foiled pointed back. These are really nice quality and you will receive 8 of these unique glass stones.
Please note: these do not have holes! Settings for these loose stones are easy to find online so you can select the exact style you want!
