An expensive piece of rock


A rare pink diamond has sold for £52,000,000 which, it has to be said, is quite a lot of money for soething that started out its existence as organic material on the sea bed.  A trip down a subduction zone and back again via a volcano turned some carbon into an object that is worth the price of 2 new schools or would pay over 1,600 teachers for a year.

Looking at the specimen close up shows that it is flawless and vivid pink in colour.  Perhaps that explain why someone would pay £4,362,416.11 per gramme, over 170,000 times more than gold.
