A Tiffany & Co. Sterling Silver .925 Spectacles Eyeglasses Bookmark. An elegant piece to use as your bookmark. It has a slight magnifying glass that I feel is more for ascetics but does give some magnification. The bookmark is in good condition, some silver polisher would make it look even better. The piece weighs 11.7 grams on my scale. The piece is stamped on the reverse side and is guaranteed 100% authentic. It comes with an outer Tiffany & Co. blue box.
