Such a diamond comes onto the market at most every 50 or 100 years, Rahul Kadakia raved about a stone called Pink Legacy before Christmas.
Raving is part of his job, because Kadakia is the head of the jewelery division at the luxury auction house Christie's, which wanted to knock the stone in the fine Geneva hotel "Four Seasons des Bergues" in November for the highest possible price - and the rule applies to diamonds in particular: the rarer, the more expensive.
She pulled this time too.
The diamond industry has lived on such legends since the ancient Greeks saw gemstones as "tears of the gods".
But their nimbus is threatened.
