I have listed the size. My tastes have changed, so I am selling this item at a reasonable price. I purchased this at the Machida store approximately 25-26 years ago. At that time, the back did not have an engraving. Old items like this are rare, so I think it's unusual. It features a decorative sun god design in silver and K18. - Design: Cross pendant - Material: Combination of silver and gold K18 - Features: Decorative sun motif in the center *I haven't used it for over 20 years.
