Dicaprio Warns Diamond Buyers

Leonardo Dicaprio is urging potential diamond buyers to check the authentification of gems before paying, so they can ensure the stone isn't a "conflict diamond".

The 32-year-old actor is currently promoting his new movie Blood Diamond, which chronicles the corrupt days of 'blood diamonds' in Sierra Leone, when the precious gems were used to finance civil wars and rebel activity which killed thousands of Africans.

When asked if DiCaprio had bought any diamonds recently, the actor replied, "Well, I don't remember the last time I have. My mom is the only person that I would buy something like that for, and for a while now she hasn't wanted one. But that isn't to say that people shouldn't buy them."

"From my conversations with Global Witness or Amnesty International, you have to go into the stores and buy these diamonds and ask for a certificate, ask for some sort of authentication that this isn't a conflict diamond. That's one of the biggest ways that this whole process can be put to a stop."
