Unusual Vintage Sterling Silver Abstract Brooch Pin

This fascinating find came from our grandmother’s vintage jewelry collection. We are not sure when or where she got it. It is stamped only HAND MADE STERLING on the back. We found nothing even similar online to its fluid, free-form, sculptured shape. It does have some scratches on it as visible in photos, but they are not so visible to the naked eye.
