This is an opal ring by WWAKE, which was also sold at Ron Herman. WWAKE is a fine jewelry brand based in New York (Brooklyn). It's a slim and simple ring, but the blue of the opal is very vivid and beautiful. The material is 14K gold, and the size is a size 9. There is an engraving on the back of the ring. Original price: 58,000 yen It's a beautiful item, worn only a few times. There are no noticeable scratches or stains, but please understand that it has been owned by someone before purchasing. This slim type is already sold out, and I couldn't find any images, so I've included a reference photo from the official website of the thicker version of the same series.
