I was given this ring by my ex right before we broke up. It has noticeable tarnishing (which I'm told is what the gold poking through is from) and it clearly has some history. I've only found one other like it on etsy. They identified as a 1990's art deco style wedding stacker ring. Not sure how accurate it is, but yknow. I was curious if anyone can tell me if they have seen a ring like this before or know anything about its history or manufacturer?

I have this ring from my ex and he bought it from eBay right before our breakup so I don't know much about it's history. He knew I preferred silver and hated gold, so when I was given this ring I was confused to see that it was stamped 925 but somehow looked like a dual tone between silver and gold. The lighting in the pictures hide it a bit, but it's still visible. I'm not sure if it's possible to be oxidization but I don't even wear it for obvious reasons. I have another ring made of silver that is starting to show signs of the same gold-ish color showing around the edges, but nowhere near as bad and I wear that one everyday.

I was gifted this ring. The setting is in stamped sterling silver. The stone has two big inclusions and a bunch of minor bubble inclusions. However, despite them, it's incredibly clear that the images just suck. I was thinking diopside or tsavorite. Can anyone identify it?
