The U shaped drop is done in hand painted patina with turquoise, brown and specks of gold. The half circle is rack plated with 18 K gold plating and does a lot to enhance this stylish geometric earring. Rack plating means that each piece is hung by hand so that they receive the optimal amount of coverage which creates a very glossy finish. The sculpted hook is brass. The earrings are lead safe. The full length of the earrings is 2" and the width is 3/4".
