Hoop Earrings with Diamonds in White Yellow Gold.  These hoop earrings are entirely contemporary. Their sleek look and minimal design are so striking and unique, it is hard to turn away. We love the combination of 14k white gold post backs and the yellow gold hoop shape dropping well below the ear. .33 carats of round brilliant cut diamonds add just the right amount of glamour, taking these striking modern earrings to the next level.
