Diamond Onyx Dangle Earrings in White Gold Platinum.  These modern dangle earrings feature 1.64 carats of diamonds finished in platinum and 18 karat white gold and gracefully holding pieces of onyx at the bottom. The earrings start with a bezel set diamond and connect to a series of links that are adorned with diamonds all the way to the onyx. This design provides a large amount of movement for the diamonds to catch light and refract, while the onyx creates a dramatic contrast that adds to their amazing look.
