Dr. Herman Grutter (Ph.D., P.Geo) has 35+ years of experience in the diamond industry: Twelve early-career years with De Beers in Kimberley, Johannesburg and Toronto in mine geology, R&D, exploration and generative geoscience roles, followed by four years with Mineral Services Canada as headline consultant and consulting services manager based in Vancouver, Canada. For six years prior to the sale of the Ekati diamond mine (April 2013), he was Commodity Specialist (Diamonds) for BHP (then BHP Billiton). During this time he provided M&A-supportive techno-economic analysis for BHP covering nearly all known global diamond deposits and was integrally involved in the discovery and first-order assessment (by BHP and joint-venture partners) of approximately 300 virgin kimberlites in Angola, Botswana, Sierra Leone, Mauritania, northern Australia and numerous East Arctic projects in Canada. As VP Technical Services for Peregrine Diamonds, he was responsible for the development of the Chidliak diamond project (Baffin Island, Canada) until that project was acquired by De Beers Canada (in September 2018). He was Principal Consultant (Geology) for SRK Consulting (Canada) until semi-retirement in June 2025.

Dr. Grutter obtained his B.Sc. (Hons) degree in geology from the University of Cape Town in 1986 and his Ph.D. in hard rock petrology from the University of Cambridge in 1993.
