I bought this from an antique shop in Scotland about 15 years ago. I don't have the original purchase memo, so I don't know the details, but it appears to be handmade, with the number 1511 engraved on the back. The photos vary slightly in color due to the lighting, but the actual item is closest to the gold color in photo 1. Upon close inspection, some of the gold plating is peeling (photo 3), and while it's not particularly expensive, it's cute, so how about it as a winter accessory? The crystal part measures 4.8cm x 4.8cm, is 1cm thick, and the chain is 66cm long.
