Diamonds are among the most captivating natural resources, carrying immense economic promise across Africa, Canada, and beyond, yet their impact on development remains deeply contentious. Economist Paul Collier has spent decades unpacking why resource wealth often fails to deliver broad prosperity, offering insights that shed light on the diamond conundrum in resource‑rich countries such as Zimbabwe and others. His work pushes policymakers to look past geology and focus on governance, accountability, and long‑term strategy in managing mineral wealth.
Diamonds and the Persistent Puzzle of Resource Wealth
Natural resources have historically been seen as a shortcut to economic development, with nations hoping that exports of oil, gold, or diamonds will fund infrastructure, jobs, and social services. In practice, this outcome is far from guaranteed: many resource‑rich states experience stagnation, instability, or corruption instead of inclusive growth. Collier’s research provides a systematic framework for understanding this paradox — known broadly as the “resource curse” by spotlighting the political and institutional conditions under which resources help or hinder development.
In Collier’s view, the problem often arises when significant rents from commodities concentrate economic power in the hands of a few, weakening governance and reducing incentives for broader investment and diversification.

Diamonds, in particular, are uniquely susceptible to this pattern because their high value and ease of transport make them difficult to monitor, highly attractive to rent‑seeking elites, and prone to smuggling and opacity, all of which can undermine public benefit and national development. His analysis goes beyond simple theory to illustrate how the global resource wealth debate applies across continents and commodity types, with diamonds standing out as both an opportunity and a test for governance.
Zimbabwe’s Diamond Sector in Context
Zimbabwe’s diamond sector grew rapidly after the discovery of major deposits in the Marange fields in the early 2000s, an event that generated intense hope for economic transformation. These deposits were some of the most prolific in terms of volume globally, positioning the country to benefit significantly from rough diamond exports. Over time, however, the developmental impact of this wealth has been limited, with much of the expected revenue failing to translate into broad economic change.

Analysts point to governance challenges and limited transparency as core reasons why Zimbabwe has struggled to harness its diamond wealth effectively. Reports have raised concerns about opaque sales mechanisms, weak reporting practices, and limited avenues for public accountability, undermining broad‑based benefits from this valuable sector. According to a policy brief on Zimbabwe’s natural resource profile, the extractive industry contributes heavily to export earnings but often fails to deliver the inclusive development that its scale might warrant, with issues such as illicit financial flows and weak governance cited as obstacles to realising full potential.
Comparing How Different Countries Manage Diamond Wealth
Zimbabwe’s trajectory contrasts with the experiences of other diamond‑producing countries that have taken different institutional paths. Botswana is often cited as a model for managing diamond revenue effectively: early investment in governance frameworks, transparent revenue management, and long‑term planning enabled the country to fund education, infrastructure, and economic diversification through its diamond partnership with De Beers.
By contrast, other producers such as Sierra Leone and the Democratic Republic of Congo illustrate challenges similar to those Collier identifies: weak institutions, post‑conflict fragility, and informal markets that make it harder to ensure that mineral wealth yields broad benefits. These cases show that outcomes vary widely even among countries with similar resources, underscoring Collier’s central insight that institutional quality, not resource abundance, is the decisive factor.
Institutions Over Geology: The Core of Collier’s Argument
A central theme in Collier’s work is that natural resources like diamonds act more as a governance challenge than an economic boon in and of themselves. Diamonds, by their nature, create concentrated rents that can distort political incentives if institutional checks and balances are absent. Countries with transparent reporting frameworks, credible regulatory environments, and strong oversight mechanisms can channel mineral revenues into broad development, while those without such institutions often see wealth captured by elites or diverted into non‑developmental uses.
For Zimbabwe, the diamond sector remains a stress test for institutional capacity. Efforts to reform reporting and accountability mechanisms have public support, but much work remains to align governance practice with broader development goals. As Collier argues in his research, addressing these structural challenges is essential to ensuring that resource wealth operates as a blessing rather than a burden.
Cracking the Code: Value Addition and the Global Diamond Chain
Collier’s framework also encourages countries to think beyond the export of raw materials toward greater engagement in value chains. In global diamond markets, countries that develop cutting, polishing, and trading capabilities capture more value and create more domestic economic activity. While this is conceptually appealing, it remains difficult in practice for many producing countries, including Zimbabwe, where limited capital, skills gaps, and entrenched global market structures have constrained the development of downstream diamond industries.
Value addition requires not only investment and infrastructure but also stable policy environments and investor confidence — factors that are central to Collier’s broader prescriptions for turning resource wealth into long‑term economic gain.
Global Markets, Incentives and the Resource Curse
International demand for diamonds shapes the incentives and behaviour of producing states, often in ways that complicate national policy aims. Smuggling, price opacity, and cross‑border leakage can undermine domestic revenue goals, illustrating how global market conditions interact with local governance environments. Collier’s research emphasises that while domestic policy is essential, it must be understood within the context of global commodity markets and institutional conditions beyond national borders.
Are Resource Outcomes Fixed or Changeable?
Collier rejects the notion that the “resource curse” is an inevitable fate for diamond producers. Rather, he argues that policy choices, institutional reforms, and deliberate governance improvements can alter trajectories over time. Botswana’s experience stands as evidence that resource wealth can be managed for broad benefit, while Zimbabwe’s ongoing reforms highlight that change is possible but requires sustained effort and inclusive governance strategies.
Paul Collier on Diamonds, Institutions and the Future of Resource Wealth
Paul Collier’s work provides a compelling framework for understanding why diamonds and other valuable resources can produce vastly different outcomes across countries. His core insight remains essential for policymakers, investors, and civil society actors alike. For Zimbabwe and other diamond‑producing nations, the question is not simply how much wealth lies beneath the ground, but how effectively that wealth is governed and deployed for long‑term, inclusive development.
Diamonds, in this sense, are not just a measure of geology but a test of governance. Their value to society depends on choices made today about transparency, accountability, and institutional strength.
