Mintek team interviewed for JCK Online magazine

The Kimberley Process Certification Scheme (KPCS) was established in South African in 2003. The aims of this group are to stop the flow of conflict diamonds, particularly on the African continent. The Mineralogy Division of Mintek plays a crucial role as the Scientific Chair of the Working Group of Diamond Experts under the KPCS. In 2013 an embargo was placed on the Central African Republic and diamonds from this country have been examined in the Mineralogy Division in an effort to determine a fingerprint of diamonds from the Eastern and Western production areas of the CAR. The efforts of this have been published in a recent article in the journal Heliyon (Brill et al., 2020) and a follow-up interview took place with Robert Bates from the JCK Online MinMagazine, New York City. Susan Brill, Nosiphiwo Mzamo and Dr Desh Chetty, all from the Mineralogy Division, were interviewed about the Provenance laboratory that is housed at Mintek as well as the scientific approach that they used in determining the fingerprint of the diamond parcels in question.
