Mateo's earrings are detailed with glossy onyx cabochons at the hinged drops - designer Matthew Harris told us they're one of his favorite gems to work with. Handcrafted from 18-karat gold, they're inlaid with 0.55-carats of round-cut diamonds along the bars. They'll look so chic with an optic-white gown.
