This design is called the Simple Hoop, and it comes in other color options as well. Each one is about 1.2" or 30mm in circumference and 9mm wide. Take a peek at how they look on the model to get an idea of the size and scale. These earrings are fashioned with vintage lucite components from Best Plastics, crafted in Rhode Island between the 1960s and early 80s. We carefully attach them to surgical steel earring posts with durable surgical steel and acrylic backings. They're lightweight and playful to wear.
