Unique Handmade Brooch

The backing is a scooped bronze tone disk. The top side is domed wire covered in prong set, clear rhinestones. The design on the wire is four hearts with the bottoms meeting in the center of the brooch. This brooch is domed nearly 1” and has open space under the rhinestone design. The photos should help with the description. The back looks fairly crude, like the pin mechanism has been soldered on, but it’s in good working order. (maybe this started out as a large button-?) One of the rhinestones is missing, but this piece is so interesting and unique, I don’t think it matters. Awesome vintage brooch.
