Rare pink diamond goes on display in France 100 years after amateur heist

A rare pink diamond is going on display in France for the first time since it was stolen almost 100 years ago to the day - the last time it was shown to the public.

The nine-carat, pear-shaped gemstone known as the "Grand Condé" was pilfered in an overnight raid on the Château de Chantilly in October 1926 and concealed in a hollowed-out apple.
