It’s no secret that a little blue box from Tiffany & Co. is almost always (at least one) key to a woman’s heart. Not coincidentally, the whimsical ?TIFFANY KEY is also a signature symbol for the revered ?jewelry brand — almost as much as the little blue box. The vintage skeleton key has been featured in everything from necklaces (as diamond-crusted, sterling-silver, even black-jade pendants) to bracelets to, well, key rings. Essentially, it has made its mark on just about every facet of the company — except for Tiffany’s eyewear. Until now.
