Dar Es Salaam: Petra Diamonds says it has recently recovered what it describes as an “exceptional” 32.33 carat pink diamond from a mine in Tanzania and has sold it for $15m, which equates to a price of $463,965 per carat.
The diamond was bought on behalf of Israel-based diamond manufacturer, M.A. Anavi Diamond Group. Petra said it has also retained an interest in the polished proceeds of the rock – it will receive 10 per cent of the “value uplift.”
In December 2015, Petra Diamonds sold another exceptional 23.16 ct pink diamond, also recovered from the Williamson mine, into a partnership deal for $10.05 million, or $433 938/ct, with Golden Yellow Diamonds. Petra retained a 20% interest in the sales proceeds of the polished diamond.
The Williamson mine, located upon the 146 ha Mwadui kimberlite pipe, is renowned for beautifully rounded white goods and ‘bubblegum’ pink diamonds, including the 23 ct Williamson Pink (54 carat rough stone), which is considered to be one of the finest pink diamonds ever recovered.
