Timeless Tiffany & Co. Diamonds by the Yard collection by Elsa Peretti. This is the .17 diamond which is the largest available set in silver. It is set in the standard 16” Tiffany’s chain. I purchased it directly from Tiffany’s myself and it is 100% authentic! It will come with the blue diamond felt hard covered Tiffany’s box, the blue cardboard box that came in, along with a copy of the original receipt (minus my card information) to the purchaser. I also just had it cleaned by Tiffany’s in April so she is sparkling and gorgeous…ready for her new owner! ♥️ 💎 Feel free to use the comments if you have any questions! I’ve owned Tiffany’s for decades and it’s one that always appreciates. This necklace is also sold out online, FYI.
