This is a 4℃ 10KPG ring, size 6. The color is pink gold and it has four diamonds. I wore it once after purchasing it, but I haven't used it since and have stored it in a dark place. I don't see any rust or stains. Please be aware of minor initial scratches. I will include the original box and warranty. I haven't had it resized or engraved, so I think you can have it resized or engraved at a 4℃ store. Retail price: 52,800 yen Product number: 111436441103 It's still sold on the official website. Feel free to ask any questions! Instant purchase is OK.
