Good product, am trying to figure out how to wrap it myself because I don't like the bead on the string idea it usually twists the gem sideways, and having OCD it's a little obnoxious when I play with it to feel it twisted.  I wasn't expecting a necklace tho so I can't complain about it too much because I am happy with what I ordered. No visual imperfections such as scratches or nicks so I'm happy with it!!
