Silver ring from agate. The antique-style belt design is cute. I purchased this here, but the size didn't fit. The previous seller also didn't know the exact size, and it was estimated to be around size 14-15, but I feel it's more like size 15-16. Inner diameter: approximately 19mm *Please refer to the images for confirmation. *The box is for photography purposes and is not included. I received it in excellent condition with little use. There are some minor scratches if you look closely, but they are not noticeable. I only tried it on once and have kept it carefully stored. Please understand that this is stored at home. Please refrain from purchasing if you are concerned about minor oversights. For those who like vintage items...・:*+
