Suspended crystals of various shapes and sizes are delicately balanced throughout the Calderi Mobile Crystal- Rutilated Quartz Earrings. The construction of the Calder Mobile earrings allows the crystals to subtly dance. Playful and modern, the crystals in these earrings are encased by sterling silver, which has been texturized and coated in a gold wash. These earrings are perfect for any causal or formal event.
