This is an authentic Tiffany & Co. Diamond by the Yard necklace, a timeless design created by Elsa Peretti, who began designing for the brand in 1974. Crafted in 18k rose gold, it features a bright, eye-clean 0.10-carat diamond. The necklace measures 16 inches and is in excellent, gift-ready condition with no visible wear. It will arrive in a Tiffany box and pouch. This design currently retails for approximately $1,360. Please note due to the rising prices of gold and Tiffany’s raising prices I cannot entertain offers. Thank you for your understanding.
