Mostly replicas of famous pieces, royalty and celebrities wearing said pieces and some general info about diamonds.. I don't know what I expected for 10 euros, but I was indeed underwhelmed.

Museum Quarter (Museumkwartier)
Top sites to see in this attractive and affluent part
of town include the Rijksmuseum and the Van Gogh
Museum, to name but two of the highly acclaimed
museums of the aptly named Museum Quarter. And if you
need a break from all the fantastic art, there’s the
Neoclassical Concertgebouw music hall and Vondelpark,
the city’s largest park. Shopaholics and luxury brand
connoisseurs will love exploring the high-end shopping
