These traditional earrings are made of 2 pieces of 7x5 mm oval genuine black onyx. The size of the earrings is 11/16 inch x 3/8 inch or 1.8 cm. x 0.9 cm. The stones are hand set in high polished brass prong settings and layered with rhoduim. Leverback earrings are so comfortable and eye catching that you will not want to take them off.
