Amsterdam likes to call itself a city of diamonds but it is a pretty tenous link. Diamond cutting thrived in the 19th century, when stones were imported from South Africa but today the diamond tours you can go on are little more than excuses to sell. Coster Diamonds, founded in 1840, was charged with repolishing the 108.8 carat Koh I Noor diamond by Britain's Prince Albert and there is a replica in the entrance Hall. Gassan Diamonds is in a rather wonderful building with two synagogues in the yard - diamond cutting was one of the few trades open to the Jews.
