Petra Diamonds Confident it will Deliver
Petra Diamonds, mining in South Africa as well as Tanzania, conduct four underground* mining operations: the Cullinan Mine (originally the Premier mine – SA), the Finsch mine (SA), the Koffiefontein mine (SA), and the Williamson Mine (*underground and open cast, TZ). The annual caratage recovered from both the Williamson and Koffiefontein is less than 300,000 carats (avg. 2021/2), while the Cullinan and Finsch produce well over 1 million carats.

Williamson: 228,070 carats FY 2022 Production
Koffiefontein: 59,151 carats FY 2021 Production
Finsch: 1.3m carats FY 2022 Production
Cullinan: 1.6m carats FY 2022 Production

Petra had earlier estimated total recovery for this year at under 3 million carats, revised estimates place that number at close to 4 million. Fiscal year 2024 and 2025 estimates show continued growth expected.

Interviews with Aussie retailers are more telling than just their stories about beautiful pink diamond jewellery.

The vast majority are signed by esteemed makers, from inventive creations by René Boivin, Jean Schlumberger, and JAR to classic styles by Van Cleef & Arpels, David Webb and Harry Winston."
