Tiffany and co diamond by the yard pendant designed by Elsa Peretti. The necklace is set with a .07 carat diamond and measures 2.8mm. This is in excellent gift giving pre loved condition and shows little to no usage. The diamond is white and I do not see any flaws with the loupe. It is an absolutely beautiful Diamond. The sterling silver 16” necklace is made of .925 sterling silver. All my items are 100% authentic. This includes An authentic Tiffany box and generic pouch.
