A Tiffany & Co. engagement ring featuring a sparkling diamond set in a platinum ring. Purchased from a department store authorized dealer and only used a few times, so it is in beautiful condition. The retail price has increased considerably, likely exceeding 300,000 yen, making this a great deal. Please feel free to comment if you'd like to negotiate the price! ★ No personal engraving. ★ Cleaned at a Tiffany store in 2024. ★ Regarding size adjustment, Tiffany Japan confirmed that you can get a free size adjustment at their stores if you bring the included certificate and the card showing the purchase date (pictured in the second photo)! Also selling a wedding band/half eternity ring as a great value set! A ring brochure will also be included!
