3 Vintage sterling silver abstract rings

So I’m listing these 3 rings together cause if size and style. Lighter simpler smaller rings and they all kinda match. All sterling silver. One is just a small circular stone pretty simple, approximately a size 7. the other 2 are onyx and mother of pearl I believe. The smooth kinda Geometric looking one is a 6-6.5 in size. The curved kinda ridged one is about a size 4. Both Kinda abstract designed and shaped. Really cool rings though. Or checkout my other listings!
