These vintage West German glass decal cabochons were made in the 1950’s-1970’s. They feature a pretty floral design in white with a blue background. I’m not sure what kind of flower they are (asters? chrysanthemums?) but they’re certainly pretty. The stones have flat backs.
Available sizes: 18×25 mm, 13×18 mm
Please note that the designs are not perfectly identical from one size to the next, but they are quite similar and they compliment each other nicely.
