The hollow organic rings of these earrings are repeated twice, designed to emphasize each other and create an elegant contrasting look. Like all of our ear jackets, this pair was designed with versatility in mind. These earrings can be worn with both pieces: together as the full ear jacket, or with the back piece removed: as a simple pair of studs. Check out our instagram page for a full show-and-tell!
