This is a ring from Ginza Jewelry Maki, famous for Camellia Diamond. They are also a brand that developed 9-karat jewelry to maintain the properties of gold while making it affordable. 9-karat gold has a lower gold content than 18-karat gold, resulting in a paler gold color, but you likely won't notice much difference when wearing it. Since the proportion of metals other than gold, known as "wari-gane," is increased, it's a harder material than 18-karat gold and more resistant to scratches. As it's solid gold, you can wear it every day without worrying about the plating peeling off, unlike plated jewelry. This ring is more for enjoying the gold material in everyday wear than for its asset value. The inside of the ring is stamped with K9, indicating the material, and the Jewelry Maki mark. Markings: K9, Maki mark Size: Size 12 Weight: 1.52 grams It will be shipped without a case. Shipping is included via Nekopos or Yu-packet. *If you prefer to receive it in person, you can switch to Takkyubin Compact for an additional 350 yen. Please let me know in the comments before purchasing. It will be shipped in a ring case. (The case is a used one from my collection and is considered a bonus.)
