Although SanaDiam’s business model is geared almost exclusively to rough diamond purchasing and selling, the company’s specialists have developed a sweet spot for exceptional coloured diamonds like the vivid purplish pink diamond auctioned by Sotheby’s in 2008. Another example of SanaDiam’s passion for coloured diamonds is the so-called ‘Chameleon’ diamond, an uncommonly large (4,89 carat) oval shaped diamond originated from Mbuji Mayi in the Democratic Republic of Congo.
