Curious why the JUC is not lucky? I'm sure it has something to do with the fact it's a nail but love to hear more...
It's not so much that it is a nail as it is the shape of the nail. I've always been taught that it was unlucky to wear jewelry with hard edges (this includes spikes, the end of the JUC nail, emerald cut stones, etc). Apparently hard edges "puncture" your luck...or something of that effect lol
