Invented the branded diamond (THE LEO at Kay/Jared, ~2,000 stores) — a diamond sold like a Nike sneaker. Owns one of Botswana's largest cutting factories: 90% women, trained from scratch, plus its own doctor when 60% of staff were HIV-positive. Crisis context: lab-grown diamonds are squeezing the whole natural industry — the moat is now brand + story, not just stones.
