Cartier 20.43ct, D-Color: The ‘Blitz Diamond’
by Simon Teakle on June 1st, 2010
In the summer of 1940, the German Luftwaffe attempted to win air superiority over southern Britain and the English Channel by destroying the Royal Air Force and the British aircraft industry. This attempt came to be known as the Battle of Britain, and the Germans saw victory over the RAF as absolutely essential if they were eventually to mount an invasion of the British Isles.
At the beginning of 1940, a South American copper and tin ore magnate arrived in London to secure a valuable contract to provide essential metals to the war effort. On this visit, he met an English girl, fell in love and an ensuing affair resulted in a swift engagement. There was now an urgent need for the best diamond in London, and on the 29th of February in Cartier on Bond Street, this 20.43ct diamond was given as the engagement ring.
Alongside this very romantic story, the ‘Blitz Diamond’ is everything an important stone should be. The pure colorless stone of extremely fine clarity (D, VS1) has been superbly cut, and for a large stone, it retains a grace and elegance that is perfectly mirrored with Cartier’s aura in the first half of the twentieth century.
