From Pit to Polish

Each Koidu diamond can be traced back to its original kimberlite source – to the exact area and level that it was mined from, to the date that the ore was crushed and the liberated stones recovered by the X-ray machines and grease table in the processing plant. The internal controls and security measures developed by Koidu Limited not only protect the valuable assets trapped within the kimberlite rocks but also prevent contamination by other sources. By strictly controlling and documenting the movement of ore from the pits, to the plant and to the final export of the rough diamonds, an unbroken Chain of Custody is created for each parcel of diamonds sold.
