Mercury is quick and appears to "retrograde" more times per year than any other planet. Our Mercury design was inspired by the nature of this planet and its associated swift-footed god. These earrings are available in two sizes: small and large. The small Mercury pull-through hoops measure 1.0″ long by 1/2″ at their widest point. The large measure 2.0″ long by 3/4″ at their widest point. Materials: 14k gold or rose gold-fill (14k gold over brass core/no nickel) or sterling silver (.925). All materials are hypoallergenic. These earrings were designed in Asbury Park and are handmade in our Upstate New York production studio.
