The Cartier signature is an encounter between expertise and a creative vision. Each creation possesses a unique character and each diamond shines with its own unique radiance. Every diamond weighing more than 0.18 carats is issued with a report from the Gemological Institute of America (GIA), an organisation that sets the standard for the quality of diamonds according to four criteria: carat, colour, clarity and cut. 

Cartier adds an additional step to these criteria with its own eye, allowing experts to identify the absolute beauty of diamonds according to Cartier’s exacting requirements.
