Blood diamond

A blood diamond, also called a conflict diamond or war diamond, is a rough diamond used by rebel movements or their allies to finance armed conflicts aimed at undermining legitimate governments, as described in United Nations Security Council resolutions and United Nations General Assembly Resolution 55/56.¹^•² The term became prominent in the late 1990s, when diamond sales financed civil wars in Angola and Sierra Leone, and it prompted the Kimberley Process Certification Scheme, the international system that now regulates the rough diamond trade.²^•³

Key fact	Detail
Definition	Rough diamonds used by rebel movements or their allies to finance conflicts aimed at undermining legitimate governments, per the KP Core Document and UN resolutions¹
Current scale	Conflict diamonds account for less than 0.1% of world diamond production, by Kimberley Process and United Nations estimates¹
Origin of the response	Southern African diamond-producing states met in Kimberley, South Africa, in May 2000 to design a framework against conflict diamonds²
Certification scheme	The Kimberley Process Certification Scheme was signed by 37 participants in Interlaken, Switzerland, in November 2002 and came into force in 2003²
Membership	60 participants representing 86 countries, with the European Union counting as a single participant¹
Key conflicts	Civil wars in Angola, Sierra Leone, and Liberia, where armed groups used diamonds to fund fighting⁴
Main criticism	The definition covers only rebel movements, excluding state-sanctioned violence, child labor, worker exploitation, and environmental degradation⁵

Origins in African civil wars

The blood diamond problem emerged from a broader pattern in which natural resource exploitation fueled prolonged and transnational violence across West and Central Africa. In Angola, rebel leader Jonas Savimbi of UNITA (the National Union for the Total Independence of Angola) rejected the 1992 elections that foreign observers judged free and fair and resumed his war by seizing control of the Cuango River Valley, the country's richest diamond territory, building a large war chest from the trade.³^•⁶

In Sierra Leone, the Revolutionary United Front (RUF) under Foday Sankoh pursued the complete control and occupation of the country's diamond fields, using amputation, rape, arson, killings, and other terrorist acts as means to that end.⁷ The civil war, which ran from 1991 to 2002, took some 50,000 lives, and the precious stones paid for the rebels' weapons.⁸

United Nations sanctions. The Security Council responded with targeted trade measures: it banned the import of diamonds from UNITA-controlled areas of Angola in June 1998 through Resolution 1173, and in July 2000 it restricted diamond exports from Sierra Leone unless certified by the government through Resolution 1306.³ The Sierra Leone sanctions were allowed to expire in 2003 after the civil war ended in 2002 and the government took full part in the Kimberley Process.⁹

The Kimberley Process

The Kimberley Process (KP) is an international initiative and intergovernmental forum to exclude conflict diamonds from the legitimate trade. It began when Southern African diamond-producing states met in Kimberley, South Africa, in May 2000, and the item was included in the agenda of the 55th session of the UN General Assembly.² After two years of negotiations, the Kimberley Process Certification Scheme (KPCS) was signed by 37 participants in Interlaken, Switzerland, in November 2002 and came into force in 2003.²

The scheme is enforced individually by participants through their national legislation; the KP has no permanent offices or permanent staff and is not, strictly speaking, an international organization or a legally binding international agreement.¹ Its core requirements are that participant countries enforce stringent legal and regulatory standards controlling rough diamond imports and exports, exchange accurate statistical data, trade only with other certified participants, and ensure that every rough diamond export is inspected and accompanied by a valid KP certificate.² Participants may not trade with non-participants, and the Plenary may suspend a seriously non-compliant participant's imports and exports; historic suspensions include the Republic of Congo, Zimbabwe's Marange area, and the Central African Republic, while Brazil and Venezuela voluntarily suspended their own exports at times.²

The KP has a tripartite structure bringing together governments, the diamond industry through the World Diamond Council, and civil society groups, which monitor the scheme's effectiveness and provide technical and administrative expertise.¹ NGOs such as Global Witness, which first exposed the blood diamond problem in 1998, and Partnership Africa Canada played an unusual role in helping write the scheme's technical document and negotiating its terms.¹⁰^•¹¹

Industry warranties. A separate industry 'System of Warranties', endorsed by all KP participants, requires buyers and sellers of both rough and polished diamonds to state on all invoices that the diamonds "have been purchased from legitimate sources not involved in funding conflict and in compliance with United Nations resolutions" and that the seller guarantees they are conflict free.¹

Effectiveness and criticism

By KP and UN estimates, conflict diamonds now account for less than 0.1% of world diamond production.¹ In countries that previously experienced diamond-funded conflicts, including Sierra Leone, Angola, Liberia, the Democratic Republic of the Congo, and Côte d'Ivoire, much greater stability has been achieved. Since hostilities in Sierra Leone ended in 2002, the country's official diamond exports have grown roughly a hundred times larger, to the benefit of the roughly 10% of its people who depend on the diamond trade for their livelihood.¹

The scheme's critics focus on its scope and enforcement. Human Rights Watch, whose researchers document business and human rights abuses, has stated that the KP's long-term credibility has been undermined by a narrow focus on anti-government rebel groups and its unwillingness to incorporate human rights protections, and that because decisions are made by consensus rather than voting, it is difficult for well-meaning countries to act against a member that violates the rules if even one other member blocks action.¹² The KP's narrow definition of "conflict diamond" does not include environmental degradation, child labor, worker exploitation, or state-sanctioned violence, which allows unethically sourced gems to reach consumers.⁵ Amnesty International has urged diamond companies to stop using the Kimberley Process to claim their diamonds are free from human rights abuses and conflict.¹³

The Russia dispute. The definition's limits became acute after Russia's full-scale invasion of Ukraine in February 2022. At the November 2023 plenary, Ukraine, backed by the United States, Britain, and other countries, asked that an investigation be made into whether the diamonds Russia produces are helping pay for its war, a proposal that Russia and several allied states firmly rejected; the plenary ended without a consensus communique for the first time ever.⁴ The United Kingdom and Canada have pressed to broaden the definition to cover state actors using diamond revenues to fund conflicts, while a 2024 UN General Assembly resolution adopted by consensus by all 193 member nations reaffirmed support for the Kimberley Process.⁴^•¹⁴

Cultural impact and consumer choices

The Sierra Leone trade inspired the 2006 film Blood Diamond, starring Leonardo DiCaprio, which linked engagement rings with their human cost for a generation of consumers.⁸

For consumers, the KP does not certify individual jewellers; a reputable business should be able to explain how its jewelry avoids conflict diamonds and whether its suppliers participate in the System of Warranties.¹ Conflict diamond expert Ian Smillie, author of Blood on the Stone: Greed, Corruption and War in the Global Diamond Trade, advises consumers to ask questions when shopping and to resist the easy answer.¹⁵ The market itself has shifted: lab-grown diamonds, marketed as cheaper and conflict-free alternatives, rose from 1% of global sales in 2015 to nearly 20%, though their environmental claims also face scrutiny because production remains energy-intensive.¹⁶
