Diamond Sourcing


The Supply Chain

The diamond trade has been the focus of criticism from the jewellery industry and consumers for decades. As awareness increased of the conditions under which ‘blood diamonds’ or conflict diamonds are mined and sold, so did attempts to regulate the supply chain and stop the trade of conflict diamonds.

Conflict Diamonds.

Conflict diamonds are mined in areas of war or areas that are characteristically plagued by violence and political upheaval
and are used by war lords/militia to finance violence.

This led to further questioning about the origins of diamonds (and later metals and gemstones) more broadly. Both consumer and industry awareness has improved drastically since the beginning of this dialogue, resulting in increased pressure from consumers and ongoing action from the industry.

Industry Response

The first initiative to surface in response to human rights offences in the diamond trade was the Kimberly Process.

The Kimberly Process set out to remove conflict diamonds from the market by controlling their movement across borders. However, the system has been criticised by several bodies for corruption, smuggling and fake certificates as well as only considering violence related to civil wars, and providing certification to countries that are rife with other forms of violence and known to have corrupt diamond trades. As a result of these gaps, a number of systems have been created to improve standards along the diamond supply chain. Below are a few examples of such initiatives.


The CanadaMark system, established by the Canadian government, guarantees the whole CanadaMark diamond supply chain adheres to the Canadian Diamond Code of Conduct. The Code was written by the government and is applicable to those who mine and sell diamonds in Canada.

The Diamond Dominion Corporation, owner of CanadaMark, is the largest independent mining company in Canada, and certifies diamonds from the Ekati and Diavik mines in Canada’s Northwest Territories. For more information about these and other active mines in the Northwest Territories see: www.miningnorth.com/mines.

Diamonds for Peace

Diamonds for Peace are an NGO based in both Japan and Liberia that are working towards a supply of ethical diamonds from Liberia and are supporting small scale miners in western Liberia.

Maendeleo Diamond Standards Certification System

The MDS certification system was created by the Diamond Development Initiative. It is for artisanal diamond production in Africa. For further information, see Maendeleo Diamond Standards – Overview and the Maendeleo Diamond Standards – FAQ’s.
