My husband bought me these beautiful earrings for my birthday. They really are very clear to the naked eye and very sparkly. I want to wear them all of the time! The blue box is nice but i feel like they totally copied cartier. Also, the included certificate really doesn't mean anything. The earrings are not certified by any gemological association hence the great price. Hubby and I are very pleased with the look of these earrings and he hates buying jewelry!
