I created these tiny hearts entirely by hand out of fine silver using metal clay: forming the clay, firing it and finishing the resulting fine silver pieces by hand. The fine silver used in metal clay is reclaimed/recycled. I've given the silver some rustic texture and antiqued it to a dark charcoal color. I love the contrast of dark charcoal silver with gold, so I created brushed-finish gold-filled earwires to complement the hearts.
The earrings are about 1 inch (24mm) from top to bottom.
