So, Nicola Tuoni sounds Italian and I found her online - but her message was in Italian! This striking pin in sleek, modern style measures 3 inches by 1 3/4 and is equally effective pointed up or down though the placement of the pin stem suggests the "wings" point down. Dark metal appears to be brass with good safety clasp and the prong set sparkly rhinestones are perfect. Excellent vintage condition.
