800 silver (European hallmarks.) Blue and clear pastes. C. 1890. Witch's hearts About 1" wide and 1 1/4 tall (including silver ring at top). The pin back, in my opinion, is uncomfortable, and if it were mine I'd have the whole pinback hardware removed so I could wear this as a pendant. If you like, we'll do this for you for free. Although you can totally wear it as a pendant WITH the pin intact if you want flexibility to wear it as a brooch sometimes. Some people say that the twisted, asymmetrical "witch's heart" shape means "bewitched by love" but I've also heard this is a 20th century meaning that antique dealers have assigned to it.
