A disappointment, especially for this girl who loves those rocks. The highlight was watching craftsmen working their magic at the very beginning. The displays had replicas and gave a perfunctory overview of diamonds and their increasing value over time. The free, quick tour ends in the Coster store, where you can see some beautiful jewelry for sale. We had a friendly sales attendant, who showed us some impressive diamond rings and bracelets (with impressive prices, too). The actual museum is a separate part, and the cost is €10 per adult (with special pricing for retirees and kids). There are 2 floors of displays (replicas) with some education. Just mediocre. read more
