This item was purchased in December 2025 and is currently sold online by Tsutsumi for 15,000 yen. (Date on the warranty card) I'm selling it because blue tones don't suit me, and I want to declutter and buy something new. I'd like to sell it while it's still in good condition. I only tried it on, and it will be disinfected with an alcohol wipe before shipping. Material: K10WG Stone: London Blue Topaz Weight: 0.63g The original warranty card and box are included. Shipping will be via Takkyubin Compact box. Due to the rise in gold prices and to prevent product substitution, returns are not accepted.
