Simple black oval onyx ring made of silver - Color: Black - Material: silver (stamped) - Stone: Onyx - Shape: Oval Inner diameter: Approximately 16mm Size: Size 10 (Japan) Purchased from an Indian jewelry store. Fits well on the finger and has a substantial feel. Also suitable as a signet ring. Thank you for viewing. I purchased this on a flea market app, listed as size 11, but it seems to be size 10, and it didn't fit the finger I wanted to wear it on. It's a very lovely item, so it's a shame, but I'm putting it up for sale. #IndianJewelry #OnyxRing #silver #SignetRing
