These cute as can be vintage glass danglers are 12 x 18mm with a thickness of 2mm. What a wonderful find within the famous vintage bead hoard. We have never seen anything quite like these wonderful vintage glass pendants. They are flat on the backside. The frontside is faceted and concave in the diamond shape of the overall shape. If you hold these up to the light, the glass has a purple transparent hue in the thinest part of the glass. That could be the center. The finish is a very reflective hematite. You could put something in the depression but it would be a shame to do that because the finish and inner faceting is what makes these so special and unique. The size is perfect for earrings. They are small for pendants, but if you wanted small dangling charm style pieces, this could fit the bill for your designs. You could also glue two together back to back for another wonderful look. You get 6 pieces per lot. Get these while they last. They are lovely but quite limited.
