The crystals are Swarovski-type imitation. I know they are not real Swarovski. But as Junaid has written, there are all types of qualities of imitations. These are a good quality for sure compared to some other cheaper imitations I have seen.
Dawn - I am not home right now. I will check and see if they are glued or sewed. I think they would be sewed??
I will try to take some more close-up pictures of the crystals so you can see the glimmer. I am satisfied.
