Nungu Diamonds Review — Bespoke Natural Diamonds in Johannesburg
Last updated: May 2026 | Independently reviewed by Diamond Guide SA
Nungu Diamonds is a black-owned South African diamond manufacturer based in Johannesburg, established in 2013. It began as a wholesaler and grew into a licensed manufacturer, producing bespoke natural-diamond jewellery and engagement rings. Diamonds are sourced from reputable South African mining companies and rough suppliers, and the brand is positioned around ethical, proudly South African sourcing. Its work has since reached international retail. Pricing is mid-range for a bespoke house.
What Nungu Diamonds Is Known For
Nungu is a boutique, bespoke-focused manufacturer with a strong ethical and transformation story as a black-owned South African business. It appeals to buyers who want a custom natural-diamond piece made locally and who value where their diamond comes from. As a younger house, its scale and price leverage are smaller than the country's longest-running manufacturers.
Nungu vs ProDiam — How Do They Compare?
Nungu and ProDiamare both South African natural-diamond manufacturers, so both let you buy closer to the source than a retail chain. The difference is track record and scale: ProDiam has 25+ years in Bedfordview with direct mine sourcing, which gives it the strongest value across retail, wholesale, and custom work. Nungu is a younger boutique with a distinctive ethical, proudly-South-African story. For the best price on a certified natural diamond, ProDiam leads; for a bespoke piece with Nungu's specific provenance story, Nungu is worth a look.
