How can you tell if a Cartier Love diamond ring is real?

To tell if a Cartier Love diamond ring is real, look for the hallmarks on the inside. A genuine ring will have the Cartier name spelled correctly in the brand's iconic cursive script. You should also see a stamp representing the metal, and it should match what the ring is. For example, Au750 or 750 will appear on a gold ring, while Pt950 or 950 will be present on a platinum one. In addition, the hallmarks should include the size in millimeters and a serial number. When in doubt about authenticity, seek the opinion of a licensed appraiser or knowledgeable dealer.
