This is a ring by Mayumi Murasawa. "Mayumi Murasawa" is a Japanese jewelry brand targeting adult women. It features simple and sophisticated designs, offering items suitable for everyday wear and special occasions. The size is approximately size 12. It's a bit large, so I wore it on my index or middle finger. The material is brass. The engraved-like design made of brass is an adorable accent. Price is not negotiable. Material: Silver
