Perfect everyday necklace, very thin and delicate, you won't even know you have it on! Box included. Authenticity Card, Bag included. The circles are not as bright as the picture from the website, a lot more subtle. Purchased June 2022. The only difference between the newer and older model is that my clasp does not have the cartier logo hanging at the closure (refer to last picture).
