For Desmond Madumetja Ratsoma, the co-founder and director of OCGems, diamonds represent far more than sparkling gemstones—they symbolise Africa’s untapped potential, craftsmanship, and economic transformation.
In an exclusive interview, the emerging beneficiator shares insights on entering the industry, overcoming challenges, and the critical role of local diamond manufacturing in South Africa’s future.
He said South Africa's diamond future lies in transitioning from resource extraction to manufacturing leadership.
This shift, said Ratsoma, requires investment in infrastructure and ethical business practices to build a sustainable ecosystem.
He also stressed the need for a robust support system – including fair rough diamond pricing, financial assistance, skills development, and global market access - to help emerging businesses weather these storms.
Ratsoma said his perseverance stems from seeing the tangible impact of their work, when locally crafted diamond pieces find their way to customers, symbolising Africa's growing capabilities in value-added production.
Below are excerpts from the interview.
What inspired you to enter the diamond sector, and what do you find most rewarding working in this industry?
Growing up, I was always fascinated by the beauty and symbolism of diamonds, and always thought they were mined in their polished form. It wasn't until I participated in diamond beneficiation [training] that I discovered the extensive journey and skill involved in their transformation. What inspires me most is witnessing local artisans grow into world-class professionals, producing diamonds that compete on a global stage—while creating sustainable jobs and uplifting our communities.
How important is collaboration in the diamond industry?
Collaboration is essential. The diamond industry is inherently global, and success depends on synergy across the value chain—from miners to manufacturers, traders, and policymakers. Partnerships, both local and international, help build trust, transfer knowledge, and drive innovation. Collaboration is key to fostering a sustainable and inclusive industry.
What role do you see for small and emerging beneficiators in the broader diamond industry?
Every multinational was once a start-up—an idea backed by courage. Small and emerging beneficiators are pivotal to the transformation of our sector. Their agility, openness to innovation, and deep roots in local communities make them powerful agents of change. They not only decentralize beneficiation but also contribute to job creation, inclusivity, and community-based economic growth.
What role has the State Diamond Trader (SDT) played in your diamond entrepreneurship journey?
The SDT has been instrumental in our growth. One of the biggest barriers for emerging beneficiators is access to rough diamonds, and SDT has consistently provided this gateway. Beyond supply, they’ve created vital platforms for exposure—such as the Hong Kong Show and their Inaugural Diamond Show, launched in Cape Town beginning of 2025 —which has helped us connect with markets and gain visibility. Their commitment to supporting local beneficiation continues to open doors for businesses like ours.
What are the challenges faced by your business given the prolonged subdued state of the market?
Global economic uncertainty has significantly impacted the luxury goods sector, and diamond sales are no exception. For small businesses, this translates into cash flow challenges and limited financial buffers to weather downturns. It’s a difficult environment that requires resilience, innovation, and strategic support.
Despite the tough market conditions, what keeps you motivated and passionate about the diamond industry?
What drives me is the transformation we are creating. Seeing a customer proudly wear a locally crafted diamond piece—that’s when it all comes full circle. It affirms our purpose. We're building something greater than a business; we're helping shape a self-reliant African diamond industry, rooted in excellence and driven by value addition at home.
What types of support are most critical for small and emerging beneficiators to succeed?
Access to rough diamonds at competitive price remains the most critical element. This must be coupled with financial support, technical training and, and access to global markets. There’s also a need for infrastructure investment and mentorship to help these businesses navigate industry complexities and grow sustainably.
What advice would you offer to aspiring entrepreneurs who want to enter the diamond beneficiation sector?
Start with education – know your product and the value chain. Then, build a solid network and find mentors in the industry. It’s a tough sector, but those who are persistent, adaptable, and focused on quality can succeed. Importantly, stay committed to ethical practices and local empowerment.
How important is diamond beneficiation to South Africa’s diamond sector and the economy?
It's vital. Beneficiation allows South Africa to retain more value from its natural resources, creating jobs, fostering skills, and stimulating economic growth. While our country is well-known for diamond mining, our future lies in being equally renowned for diamond manufacturing, innovation, and design.
What does natural diamond mean to you?
To me, Real is Rare. A natural diamond represents not just beauty—but legacy, authenticity, and transformation. Each stone has a story that starts deep within the Earth, and through local hands, it becomes a symbol of identity, love, and possibility. It reflects Africa’s potential—not just as a source of resources—but as a continent of creators and innovators.
