LEXEL... I wouldn't recommend weldbond if you wear it in the shower or swim. I tend to forget to take my jewelry off or i simply just don't take it off. Weldbond does not hold up well in moisture unless the piece is sealed thoroughly. It also takes forever to dry when you put layers of glass together. I would use Lexel. Its waterproof, crystal clear and dries in about 48 hours. Local hardware store should have it where the caulks and sealants are. Just make sure when you put the pieces together you use a good bit and press all the air bubbles out. You can use a razor blade to clean up the excess when its dry.
