Price not negotiable. *Due to the high value of this item, a tamper-proof tag will be attached for shipping.* This is a Tiffany & Co. By the Yard necklace. Purchased by myself at Daimaru Umeda store in Osaka. It is a relatively large diamond, 0.34 carats, so it has a serial number. 3EXCELLENT The metal is 18K YG. It is in beautiful condition as I have hardly worn it. Also, I had a clasp added at the store for a fee, allowing for length adjustment. Therefore, the necklace length can be adjusted to either 40 cm or 38 cm. Tiffany & Co. has significantly raised prices, and you cannot purchase a diamond of this grade at this price now. *As this is definitely an authentic product, returns are not accepted to prevent tampering. (A tamper-proof tag will be attached for shipping, so please do not remove the tag until the transaction is complete. If the tag is removed, it will be considered as a switch.)* - Brand: Tiffany & Co. - Carat: 0.34 carats - Color Grade: I - Clarity Grade: VVS2 - Cut: Round Brilliant - 3EXCELLENT - Accessories: Box, ribbon, certificate - Condition: Superb Designer: Elsa Peretti Material: Gold Line Name: By the Yard Gemstone: Diamond Color: Yellow系 Scratches/Discoloration: None
