The main 51.38-ct diamond is a 57-facet traditional round brilliant-cut diamond, Triple Excellent (the best quality cut), D, VVS1. Such characteristics occur in less than 1% of diamonds worldwide.

  • The discovery of these two stones [709 & 476-carat] means we have immense resource potential. There is excellent investor trust in Sierra Leone. The proceeds from the sale will have a knock-on effect for investors and government, and a direct impact on the community where they were found. It highlights the great opportunity to partner with Sierra Leone in terms of resources.
