Royal Coster Diamond Tour

On the corner of Museum Square, you can visit Royal Coster’s Diamond factory, which is the oldest diamond factory in the world. Here you can watch professionals cut and polish rough stones into beautiful diamonds.

An experienced guide will walk you through the factory, and tell you all about the origins of diamonds. Along the way you will also learn all about the 4 Cs of diamond valuation, cut, colour, clarity and carat weight, and much more.

The guide will also take you to a private room where you’ll see part of the largest collection of unset diamonds. Amongst these is the Royal 201 diamond, Royal Coster’s patented diamond known to be the best diamond in the world, and the Koh-I-Noor, part of the British Crown Jewels.

Yes, this tour is free but it can be fully booked, so make sure you book your free tickets online, just in case. And maybe, before you walk out the door you want to do some tax free shopping? Or maybe you want to learn even more about diamonds? Then visiting the Diamond Museum just down the street might be the perfect follow up activity in Amsterdam.
