Over one million people will get engaged on Valentine’s Day, and as a result, diamond sales usually uptick around this time. Diamonds are both historical and cultural objects; they carry meaning for many — symbolizing love, commitment, and prestige. Diamonds are highly coveted objects, and scholars have found about 90 percent of American women own at least one diamond. In the 1990s, war spread throughout West Africa over these precious pieces of carbon, as armed political groups vied for control over diamond mines and their profits.

Given their role in financing brutal West African civil wars, diamonds became associated with violence and international refugee crises, rather than financial prosperity and love. Diamonds became pejoratively known as blood diamonds, or conflict diamonds, and consumers became more likely to perceive diamonds as the result of large scale violence and rape.  As a result, major diamond producers have attempted to reconstruct the symbolic meaning of diamonds, turning them into symbols of international development and hope.

As the diamond trade became immoral and socially unjust, new global norms emerged around corporate and consumer responsibility. Non-governmental organizations (NGOs) lobbied for the diamond industry to change their behaviors and support of conflict mines while simultaneously creating new global norms and expectations. In the early 2000s, international NGOs, governments and the diamond industry came together to develop the Kimberley Process — to stop the trade of conflict diamonds. Today, 75 countries participate, accounting for 99% of the global diamond trade.

Bieri & Boli argue that when NGOs urge companies to employ social responsibility in their commercial practice, they are mobilizing a global moral order. Diamonds provide an example of how symbols, products, and meaning are socially and historically constructed and how this meaning can change over time. The case of blood diamonds also illustrates how changing global norms about what is and is not acceptable can redefine the expectations of how industries conduct business.
