The largest round fancy intense pink diamond ever at auction features at Christie’s sale of magnificent jewels in Hong Kong on May 29. The 12.04 carat stone was purchased from Harry Winston in 1976, the year the US launched it first satellite on a mission to Mars. The stone was named the Martian Pink.
It is one of only two known significantly sized round pink diamonds in the world. The 23.60 carat Williamson Pink was presented to Queen Elizabeth II on the occasion of her wedding in 1947. The Martian Pink shows no trace of secondary colour, making it very rare. Most natural pink diamonds exhibited a colour modifier like purple, orange or grey. It is offered alongside an elegant 11.85-carat D VVS1 potentially flawless round brilliant-cut diamond of D colour.
