No price reduction. No further price reductions will be made. Tiffany Solitaire Necklace PT950 Serial number on diamond and setting. Purchased from Tiffany 6 years ago. Appraisal certificate is missing. Design specification is over 0.6 carats, so the top position does not shift. Discoloration on the marcan part; it will be cleaned by Tiffany (service cleaning). Color is unknown due to the missing appraisal certificate. In my opinion, it is colorless. Please check the condition in the photos. Please refrain from price negotiations. No price reduction. I will not respond to comments regarding price negotiations. Will ship via Rakuraku Mercari delivery. Measures taken to prevent item substitution. Serial number has been recorded. Grams are measured by an amateur, so they are not accurate. Accessories: Box
