How Much is a Auction Gia Certified?
- 1stDibs ExpertApril 5, 2022Yes, Cartier diamonds are indeed GIA certified.

Shop a collection of expertly vetted Cartier jewelry from some of the world’s top sellers on 1stDibs.
- 1stDibs ExpertAugust 17, 2021In the United States, diamond rings are certified by an official gemological laboratory known as the Gemological Institute of America. A certified diamond ring means that the diamond has undergone a quality analysis by experts at an institution such as the GIA and these experts have issued a lab report that is indicative of the grading process.
- 1stDibs ExpertFebruary 22, 2021When a diamond is GIA certified, it means that the stone has undergone the meticulous set of grading procedures that have been established by the Gemological Institute of America. The GIA is not a jeweler — it is an independent, nonprofit group that sets the standards for determining the quality of a diamond.
- 1stDibs ExpertFebruary 13, 2023While diamond studs don't need to be GIA-certified to be sold, experts typically recommend that you only purchase diamonds that carry certification from the Gemological Institute of America (GIA) or Authentic Gem Security Lab (AGSL). Certifications bring transparency to the buying process, allowing you to know the level of quality of a diamond before you purchase it. Shop a collection of vintage and modern diamond gemstone earrings from some of the world’s top jewelers on 1stDibs.
