jewellery

I found this interesting piece at a thriftstore. I don't see any markings on it, and I'm curious as to what the main stone and the faceted one might be. I don't know if it's a pendant or was it to be a pin of some sort, and any thoughts if this might be custom made? It's quite heavy as well...

A few finds from yesterday's hunt... The significant being the brooch a real nice find. The coal miners check tag was great too, me being a miner...

Hi, I've been searching for gold chains online as of late, and can't help but be sketchy about italian gold, the price seems a little too good to be true... I just want to know, is there any way to verify the authenticity online or request something from the seller? Reference photos below
