I'm doing a restoration project on a recent costume purchase and replaced these stones with some new ones. One of them is quite faded. The rest are in great condition. These are 16 mm crystals. There are no holes in them, so you'd need to get a round prong setting to put them on a costume. The first photo is taken with flash and the second without.
I'm asking $25 plus shipping for all 13 stones. Paypal gladly accepted.
