Classic Hardware Jewelry ~ Frida Kahlo "Curious Heart" Toggle Clasp Necklace. A large scratch resistant red heart is beset with a resin-coated, sepia-toned image of Frida Kahlo (with what appear to be flames in the background) The over-sized heart dangles from a faceted ruby red glass beaded chain with stainless steel accent beads. We love the toggle clasp. Trademarked Classic Hardware on the clasp. Fabulous necklace for Frida collectors!!!
