Nice vintage hatpin to spice up a plain hat. This one has a large faux glass pearl encased in an engraved cup. It has a screw on cap on the end. Based on the style I'd say it is from the 1920s.

This vintage hatpin could really dress up a cloche! 3/4" wide by 6" long. I'm not sure if the end cap is original but it fits. Excellent condition.
