The Kimberly Process was introduced to try and help people ensure diamonds they purchase won’t help finance war and killing. Unfortunately the system isn’t reliable and diamonds that fuel war sometimes get a deceitful certificate suggesting they are OK. What can customers do? Antique diamonds won’t fuel any conflict so you can splash out on them with a clear conscience.
Buying legitimate diamonds can of course help economic development in the Third World but we can’t easily tell which diamonds are legit. You may prefer to look for other ways you can help the Third World.
