I am a big fan of lockets. I like the secrecy of hiding a photo or a memento inside, for only the wearer to know about. And they are usually quite beautifully detailed, as is this exemplar from the Victorian era. The front features a playing card king, and the back is made of a piece of bloodstone. It flips open from the top, rather than the side, which is a bit unusual.

Seller Doyle & Doyle notes, “Measuring approx. 1 1/4 x 5/8 inches. One side with an enamelled King of Spades card. The opposite side with a bloodstone tablet, suspended from 18 inch 14k chain. Fashioned in 15k yellow gold. Engraved “PATENT” on hinge. Circa 1890.”

This sells for USD$1,900.
