Irregular 3D Cylinder Clip Earrings are hand cast in sterling silver under 18KT gold vermeil and silver. These two-tone button earrings are easy to wear with other silver or gold jewelry. They are hollow so they will not weight your ears down and they are some of the most comfortable clip earrings we have come across. We have been carrying this artist for years and can say these timeless pieces hold up beautifully year after year. They are made in the USA.
