Natalia Collister for Avon Cubic Zirconia Silver Plate Earrings

Very pretty and super sparkly pair of dangle/drop earrings. Designed by Natalia V. Collister for Avon and dating to around 2010 (?). Silver-plated metal with three prong-set cubic zirconias in purple (amethyst), citrine, and clear. Earrings have leverback ear wires and a drop length of almost 1 inch. "NVC" is stamped on the back of one of them - see photos. These are in excellent condition - absolutely no signs of wear or damage.
