    We are so pleased with this purchase. The earrings were exactly as described. They are so nice. The shipping through the authenticator was super fast. The packing was great. The communications from the seller were also great and timely. Overall, we got a really good deal on these earrings and couldn't be happier with this entire experience!!!
