African Diamond Industry: Supply Decline, Lab-Grown Disruption, and Beneficiation
Natural diamond production from Africa is declining as older mines mature. Lab-grown diamonds are disrupting the lower end of the market. Beneficiation, cutting and polishing in Africa, is the strategic response.
Africa dominates global natural diamond production, with Botswana, DRC, South Africa, Angola, and Namibia collectively producing approximately 50 percent of world output by value. Botswana's Jwaneng mine remains the world's most valuable diamond mine by revenue. However, global natural diamond production has been declining as mature mines deplete high-grade ore bodies. Lab-grown diamonds, produced synthetically in Chinese and Indian facilities, have captured the lower end of the diamond jewellery market: a one-carat lab diamond that sold for $4,000 in 2015 now retails for under $800. Natural diamonds retain their premium for investment and high-end jewellery but face structural competition in engagement ring and fashion jewellery markets.
Beneficiation Strategy
Botswana's renegotiated De Beers contract gives Okavango Diamond Company 30 percent of production for direct marketing, part of which will be cut and polished domestically in Gaborone's growing polishing industry. Namibia's Namdeb polishing operation and Angola's Sodiam polishing facility represent similar beneficiation investments.
