The Natural History Museum in London is hosting “the largest and most spectacular diamond exhibition ever staged”. The displays trace the story of diamonds from deep within the earth to their uses in science, industry and fashion. The collection includes the famous De Beers Millennium Star and the third largest diamond ever cut. Visitors can enjoy an “explosive” film, challenging games, and a glimpse into the world of the diamond prospector. Until February 26. Open all day.
