We think the older crystals have much sheen to them. Perhaps we're dazzled by their age. We think they really are nicer. We are so enamored by these sweet little stars and the detail in them. Each is 4.8mm from point to point (almost like a diameter).
These can be sewn or, more easily, glued on to your project. We are showing several so that you might see the front and back. You may be able to remove the gold backing, but we have not tried to do this. They are flat backed for easy gluing.
