An opal ring purchased long ago from an antique shop in Kobe. It's stamped 10K. I believe the size is 11, but I don't have a ring sizer, so I'm not certain. I fell in love with the cute and lovely design featuring three opals and bought it. I'm selling it because I have too many rings. The play of color is beautiful. For opal lovers, please.
