5: The Martian Pink, a brilliant-cut Fancy Intense Pink diamond, 12.04 carats Sold for $17,395,728 in 2012
Mounted on an 18k gold ring by the famous New York jeweller Harry ‘King of Diamonds’ Winston, this ring was nicknamed ‘The Martian Pink’ by his son Ronald, who was inspired by the 1976 launch of a US satellite to photograph the ‘red planet’ Mars, and the stone’s similar strong pink colour.
The Martian was certified as having virtually no nitrogen in its crystalline structure and unlike most pink diamonds, which exhibit tones of purple, orange or grey, it shows absolutely no trace of any secondary colour. As a result, it sold for more than double its low estimate when it went under the gavel in Hong Kong in 2012.
