14k Yellow Gold Marquise Ruby “Mariposa” Earrings. The Butterfly Effect of these earrings is a head turner. Geometric symmetry meets the royal floating flower that is the butterfly. 14k Yellow Gold ensures that the earrings are lightweight, as they subtly dance around with movement. With a rich, deep red color, the butterflies are constructed out of brilliant Marquise-shaped cuts of Ruby. Nightlife is the right life for this dazzling item. Made in NYC.
