“The Rock” – the largest white diamond to ever be offered at auction – sold for $21.9 million at Christie’s Magnificent Jewels sale in Geneva, beating its low estimate of $20 million, but falling way short of its $30 million high estimate, IDEX Online reports.


The 228.31-carat, pear-shaped gem was mined and polished in South Africa and is graded a G color, VS1 clarity stone by the GIA. It is the largest existing D-Z color pear-shaped diamond ever graded by the GIA laboratory.

Another highlight of the sale was the “Red Cross” diamond – a cushion-shaped, 205.07-carat, fancy-intense-yellow gem – that sold for $14.3 million.
