I think some outlets may still have that fob. I know Prime in Orlando had two this evening. If you bring it in, they might replace it. It happened to me and they gave me a new one. The SA suggested putting clear nail polish over the stones. It protects them.
I lost one out of my dice fob also. I found it in my car. I glued it back on and put clear nail polish over each one, so far so good. Plus it really doesn't show if you cover the whole side with the polish.
I called around pretty much all they have are the cherries... I called JAX & they said I could send it in for repair. They won't send me a crystal... I'm inclined to go to JoAnn & buy a Swarovski crystal, super glue it in & call it good!
