We're not sure you can get a more classy colour combination than black and gold, which makes this pair of earrings an excellent choice to complete your evening look. Made from 9ct yellow gold, these studs each display a stunning 6mm round onyx gemstone. Stamped with a 375 metal mark, they have a front to back distance of 1.1cm and weigh just less than half a gram as a pair. Butterfly backs secure them in place.
