Identifying crystals
Hi all,
I was wondering if any of you know how to identify a crystal by just looks... whether it's AB, Swarovski, plastic, glass, or real crystal?
I have a costume from Egypt with some lovely crystals on it, which I think are AB (they have a colorful reflection in the interior). I was going to post the costume on ebay, and am not sure how to describe them.
Would appreciate any advice! Thanks!
