NWOT Silver & Rhinestones Necklace & Earrings byLC

I don’t see the silver marking anywhere but thought it was actual silver, so I’m guessing it’s rhinestone or cubic zirconium. It sparkles tremendously & is a beautiful set. The necklace fits on chain in a very cool way that I’ve not seen. I’ll add pic of it. Also the chain is like individual silver teeny tiny balls & doesn’t tarnish.
