What to do when the rhinestones on your cell phone case or jewelry are starting to loosen up?
Clear Nail Polish
Mod Podge (Glossy kind) and a disposable sponge
Apply a thin coat of clear nail polish over the rhinestones or put a small amount of Mod Podge on to a disposable sponge and gently dab the surface of the gems. Make sure the nail polish or the Mod Podge is dry before wear. In the case the rhinestones have already fallen off; use Superglue or a glue gun to stick the little guys back on.
