Pyrite ring

I’m assuming this is a true pyrite. Absolutely looks like it. It’s a size 5.25. Not adjustable, if it were, I wouldn’t be selling. Fits my left ring finger, not my right. Unfortunately (or rather fortunately), that finger is already occupied😉. The band is a gold tone. Fun ring! As always, I’M ONLY SELLING ON PM. NO TRADES. NO PERV SHOTS (just sayin).
