Purchased from Dreamtime creations but just didn't need them. Be sure of the size, 10mm is less than half inch. They have facets across the face like a chessboard. The color is a deep red but has a gold sheen to them. There are no holes for these and they are not the hot fix type. Flat back. Glue is the best method.
If you go to Dreamtime creations online and look up the number at the top of this, you can see a better photo.
