■K18 Opal Ring■ Openwork Crown Design, Split Prongs■Antique Showa Retro■Ring■Used, Polished Finish■ This is a K18 opal ring. I finally got my hands on it!!! It has a beautiful play of color depending on the angle. There are fine scratches and minor imperfections on the stone when viewed through a 10x loupe, but I think they are not noticeable to the naked eye. This ring was made in the Showa era, and the openwork design of the base and the split prongs are cute. The base supporting the stone is also lovely, and the craftsmanship is recommended. The colors seen depending on the angle and lighting are beautiful, and the captivating hues are highly recommended. The stone is not marked with its carat weight, and it appears relatively shiny for its age. Please understand that it has not been appraised. It has been cleaned and polished as much as possible, but as it is used, there may be minor scratches, surface scratches, chips, dents, and metal imperfections. Please be aware of this before bidding. Please understand that the color of the item may differ from the image due to the lighting, light, and camera. I have tried to include as much as possible in the photos.
