This is a gently used Tiffany & Co. 1837 sterling silver ring in 'medium' thickness. The size of this ring is either a 5 or 5.5, I am leaning more towards a 5.5 based on how it fits my ring finger. This ring is currently on the Tiffany & Co. website retailing for $400. The website describes this ring as "Proudly inscribed with the year Tiffany was founded, the Tiffany 1837® collection is defined by sleek curves and contours. This elegant ring embodies a timeless aesthetic." I also have a matching necklace listed for sale separately. Please note this does not come with the Tiffany’s pouch, that goes with the matching necklace I also have listed. Comes from a smoke free home.
