Harriet Bauknight for Kaso designed these stunning acrylic Lucite clip-on earrings. They feature a dimensional double ice cube in amethyst purple and emerald green, with mirror-textured patterns and asymmetric beveled edges. 
The Kaso paper sticker is no longer there, but the gray background and the distinctive rotating clipback are unmistakable brand signatures.
