Limited Edition Mystery Masterpiece

As though Mont Blanc wasn't good enough, the epic luxury pen brand came together with Van Cleef & Carpels to celebrate both their centenaries and this beautiful pen was born.  As they themselves market it, 'This is a one of a kind luxury pen that comes in three offerings.'

Basically, customers can choose whether they want a spattering of emeralds, rubies or sapphires; and any one they choose will also get the 840 diamonds that it comes with as well. The price? $730,000 only!
