Classic style opal ring made of silver. - Material: Silver - Stone Type: Opal - Design: Classic style - Size: 10 (Japanese size) The material is silver, but please note that the ring may be tarnished. There is a marking, but I can't make it out. This is a vintage item and has a sense of age. It's quite old. I'm selling it because it doesn't fit me. If you are interested, please consider purchasing. The listing is for the ring only. Thank you for looking.
