As quoted in the press release:
The larger of the two diamonds recovered has a weight of 4.77 carats with the smaller diamond weighing 0.2 carats. Options for the sale of the stones are currently being investigated.
Lucara Diamond CEO William Lamb said:
The recovery of the 4.77 carat blue diamond brings the total number of blue diamonds recovered in the past few months to four. The re-occurring recovery of these exceptionally rare and sought-after stones is highly significant and confirms the quality of the diamonds produced from the Karowe Mine.
