Tiffany & Co. ring with diamond embellishments. Retail price: 2,310,000 yen Purchased last September at Seibu Shibuya. I have discarded the receipt. Due to the high value of the item, returns are not accepted to prevent substitution. Tiffany does not issue a guarantee card, but authenticity can be proven by having it cleaned. If you wish, I can arrange this, which takes about a month. Please let me know. - Brand: Tiffany & Co. - Accessories: Box - Design: Diamond-decorated ring Size: 8 Thank you for viewing.
