THE LOUIS CARTIER DIAMOND
This perfect tear-drop diamond of 107.07 carats was cut from a rough stone of 400 carats discovered in 1974.
It is one of the very few precious stones of more than 100 carats to be certified D Flawless (i.e. colorless with zero defects) by the Gemological Institute of America (GIA).
To obtain a perfect cut requires several months of highly demanding, passionate work of the kind that was fully appreciated by the man who gave this diamond its name.
This exceptional jewel was insured for five million dollars at the time, then put on display in the company showrooms in New York to celebrate the 100th anniversary of Louis Cartier's birth.
In reporting on the event, the newspapers admiringly described the diamond as "the size of a baby's fist".
