Rare black coral cufflinks with 14K gold frames (see photo 3). MAUI DIVERS no longer carries cufflinks. Purchased from a specialty store in Hawaii about 35 years ago. The 14K gold purchase price at a certain store on January 16th was 14,912 yen. Although hardly used, there are minor scratches and signs of aging on the back. Stamped 14K. The part that attaches to the sleeve is different. No MAUI DIVERS stamp. I contacted MAUI DIVERS, and they said that products from 35 years ago did not have stamps. I remember it was expensive, and upon checking, gold was used for the frames. I had it appraised in Okachimachi. Please ask any questions before purchasing.
