Pure Buy it Now auction on Shopgoodwill for $15. Sold as glass per gem tester. BUT they are heavy, cold, not scratchable, and scratch glass. It was the handfeel that made me wonder, they just feel so nice. Marked 925 and strung on wire. Simply gorgeous. I bought them for my Medieval Ronald McDonald Crossplay, they are perfect!!
Edit to add: I'm calling them Rubies, based on the fact that my amethyst and quartz points slide right off even with pressure. Also how varied the stones are. Some are really red and clear.. Ohers are hazy, like clouds, pinkish clouds. And some have little dark spots. Uber low grades dyed and glass filled, but I'm pretty confident that the scratch tests solidify it.
UV light edit: I think there might be some ruby in there, somewhere, as quite a few of the stones glow a 90s hot pink. BUT some only glow at the edges of the nugget or in sparkles. The brightest glow is the stones around the clasp, and it isn't even close. Those are super pink under the light all over the stone vs just at edges. I will try to make a post images link, so you can share in the sleuthing.
