A 10-64 carat fancy vivid purplish pink diamond sold for HK$155m
According to the GIA report, the diamond weighing 10.64 carats is in D colour, displaying an exceptional transparency that typifies a Type IIa gem, which represents less than 2% of all diamonds mined. It has been afforded the grade of internally flawless gem, and to describe it as ‘crystal’ would be an accurate description. The exceptional size of the diamond was achieved as a result of precise polishing down to 0.01 carat, in order to preserve as much weight as possible whilst producing a flawless clarity.
Diamonds, unlike some gems that occur in a limited range of colours, comes in a wide spectrum of rainbow hues. However, most diamonds form in the colourless range, or with tints of brown and yellow. It is extremely rare for a diamond to embrace the vibrant, attractive colours of pink, blue, red, green or violet. Diamonds that are over 10 carats are rare for colourless diamonds – but even rarer for coloured diamonds. In 2002, GIA conducted a data analysis on over 1,400 pink diamonds – and only 1% of all the pink diamonds that was graded was bigger than 10 carats. The fact that this fancy vivid purplish pink diamond weighs 10.64 carats is an astonishing marvel.
The diamond was hammered down at HK$135m, below its estimate of HK$150m-200m, and sold for HK$155m after premium.
