Beautiful white onyx and silver ring, stamped 925. - Brand: Royal Copenhagen - Material: Silver - Design: White onyx decoration - Stamp: 925 - Accessories: Original box Thank you for viewing. This is a Royal Copenhagen ring I received about 30 years ago. I was captivated by the beautiful white ring and often wore it in the summer. I haven't worn it in over a decade, so I've decided to put it up for sale. I believe the white stone is not ceramic. The base is likely silver. The size is approximately size 12. I hope you will consider purchasing it as a vintage ring. There are no accessories other than the box. Thank you for your consideration. Looking for
