Donut bails for Swarovski #4439 crystals give you an easy way to turn square crystal rings into a pendant, rather like a setting for a crystal stone (they are not designed to be taken on and off). Some styles have a loop so you can dangle a charm inside, and some are classic and smooth, with no extra loops.
Gemstone donuts and other handmade or natural material donuts and pendants vary in diameter from item to item and batch to batch.
