Do not support potentially harmful ways of mining and extracting precious metals and gemstones. Respect the international standards of the field and recommend upholding working standards and human rights to avoid the exploitation of miners. Support and recommend the Kimberley Process Certification Scheme (2003) as a way to push the (diamond) industry forward when it comes to preventing conflict diamonds from entering the diamond supply chain. Require suppliers to certify that diamonds are sourced in accordance with prevailing standards.

Businesses must work towards a stronger commitment between retailers, suppliers and subcontractors to reinforce the development of a secure mining industry

The mining and production of precious metals and gemstones takes a strong toll on nature. With the tremendous profits that stand to be made, there is the risk that mine owners will exploit workers. Furthermore, so-called blood diamonds or conflict diamonds threaten the making of a responsible business. Conflict diamonds are mined in war zones and often sold to finance the activity of a warlord or a violent group. NICE recommends doing the utmost to eliminate the market for that kind of business out of respect for the victims of the conflict and because of the fact that only by advancing responsible and sustainable business processes within the extraction and mining of precious metals and gemstones is it possible to face consumers openly and to create a viable business in the fashion industry.
