Silvertone and CZ Pave Butterfly Stud Earrings We brought you the Sterling Silver CZ butterfly ring, and the matching necklace. Now, we've completed the set with our Mariah Inspired CZ Butterfly Earrings! Each sterling silver stud earring features a delicate butterfly outline, with the two tiny CZs between the wings They're not quite as bling-tastic as the ring and necklace, but the understated design is a perfect compliment to the rest of the set.
