This is a blue ring from Jewelry Tsutsumi. I bought it for myself as a reward three years ago, but I only used it for about a month because of swelling caused by side effects from medication for my illness. Please read everything below. Please note that the ring size is large, so it may not fit those with slender fingers. ● Ring Size: Size 16 ● Width: Approximately 2.5-5.5cm ● Metal Material: K10WG (White Gold) ● Gemstones Used: Sapphire, Iolite Blue Topaz, Aquamarine ● Accessories: None ● Other Notes: I will clean the ring with an ultrasonic cleaner before shipping, but there may be fine scratches and dirt. Please use the paid cleaning service at Tsutsumi stores. I will wrap the ring in cushioning material and send it via Nekopos (a Japanese delivery service). Please check the photos and understand that this is a used item before purchasing. There is no case or warranty. Therefore, the price is set at a bargain. I had it cleaned once at Tsutsumi. Please refrain from purchasing if you have any concerns.
