Kanye West has donated his $360,000 (GBP200,000) diamond encrusted watch to London's Natural History Museum in support of diamond conflict charities.

The rapper made the generous donation after an early recording of his hit single DIAMONDS FROM SIERRA LEONE prompted hip-hop colleague Q-Tip to educate West about the criminal culture surrounding conflict diamond trade.

The gold timepiece is encrusted with white and black diamonds, which depict West's face.
