I purchased this from Rakuten shop, Yokoyama, a shop specializing in birthstones and gemstones. I bought it just the other day, but unfortunately, the size doesn't fit the finger I want to wear it on, so I'm reluctantly putting it up for sale. I tried it on once, then disinfected it and stored it. I will ship it with the quality certificate and the included plastic case. Material: silver 925 Stone: Cubic Zirconia Size: 10 Retail price: 6,282 yen
