It’s a time of exceptional diamonds


Exceptional diamonds are forever and the last few months have been an epoch of new exceptional diamonds. In the wake of the discoveries in Botswana (Lucara Diamonds Karowe kimberlite south lobe – the 1,111 ct Type IIa Lesedi La Rona and several other large diamonds) and in Angola (Lucapa Diamond Company – 404 ct recovered in the Lulo project, recently sold by 16 million USD), Petra Diamonds recently announced the discovery of an exceptional 32.33 carat pink diamond from the Williamson mine in Tanzania. This diamond was sold for US$15.0 million (US$463,965 per carat); Petra Diamonds also retains an interest in the polished proceeds (Petra will receive 10% of the value uplift of the polished).

Both the Karowe kimberlite (especially its south lobe) and the Lulo alluvials (and the close by kimberlites) are establishing a name as new sources for very large diamonds. Relatively new technological developments – the XRT diamond recovery machines, have also had a major contribution in the surge of discoveries.
