Diamond Museum Amsterdam

This guide to the Diamond Museum Amsterdam opens in 1851, when the legendary Koh-i-Noor diamond went on display at London's Great Exhibition and left crowds unimpressed by its flat, ancient cut. It follows two master polishers, Fedder and Voorzanger, sent from an Amsterdam diamond house in 1852 to recut the stone under Prince Albert's anxious watch, working a steam-powered mill for thirty-eight days. You're standing steps from the Rijksmuseum, in what was once the diamond capital of the world.
