Pro tips to help you make a pick

If comparing tour types, private guided visits offer greater flexibility for questions about famous diamonds, techniques, and industry secrets.

Pairing Royal Coster Diamonds with the Rijksmuseum often costs less than booking both attractions separately and simplifies itinerary planning.

Early afternoon slots frequently align well with a Rijksmuseum visit, reducing unnecessary cross-city travel and maximizing sightseeing time.

Check cancellation terms before booking, as flexible tickets can be useful when coordinating museum reservations, canal cruises, or day trips.

Digital tickets are typically accepted, allowing faster check-in and eliminating the need to manage printed documents during a busy Amsterdam itinerary.

Did you know?

Royal Coster Diamonds is the world's oldest operating diamond polishing factory, continuously refining diamonds since 1840 through generations of master craftsmen.

The company was entrusted with repolishing the Koh-i-Noor in 1852, improving its brilliance for Queen Victoria's Crown Jewels.

Craftsmen spent 38 days hand-polishing the Koh-i-Noor, reducing its weight dramatically while creating the dazzling sparkle admired today.

More than 60% of a rough diamond is sacrificed when creating a Royal 201, making each finished stone remarkably rare.

One of Royal Coster's master polishers earned a Guinness World Record for polishing an extraordinarily tiny diamond in 1994.
