Are Cartier diamonds real?

Yes, Cartier diamonds are real. The French luxury jewelry maker follows stringent standards when selecting the diamonds that go into its pieces. For example, the central brilliant cut diamonds in Cartier rings that are over 0.3 carats in weight must be classified as Very Good or Excellent to be used by the brand, and Cartier rarely chooses diamonds with clarity ratings below VS2 or color ratings below H.
