Visit Royal Coster Diamonds, the oldest diamond factory in the world, on a 45-minute guided Diamond Experience tour with live demonstrations.
Getting started
Enter the Royal Coster Diamonds factory using your included entry and check in for your scheduled 45-minute guided Diamond Experience session. After a brief introduction from your diamond expert, you join a small group and move into the working areas of the factory. The tour starts indoors, so you can focus straight away on the craft and stories behind the diamonds.
What to expect
Over 45 minutes, you'll move between historic villas, active workshops, and private display rooms while uncovering the story of Amsterdam's diamond industry. Watch artisans carefully polish and set diamonds, learn how specialists evaluate a stone's quality, and see famous diamonds and replicas up close. Rather than focusing only on finished jewels, the experience reveals the skill, precision, and craftsmanship required at every stage of the process.
Features
Visit the world's oldest operating diamond polishing factory: Walk through the historic home of Royal Coster Diamonds, where generations of craftsmen have worked with some of the world's most valuable stones. The factory remains active today, offering a rare look at diamond polishing in progress.
Learn the 4Cs of diamond valuation: Discover how cut, color, clarity, and carat weight influence a diamond's appearance and value. By comparing different stones, you'll begin to spot details that are often invisible to an untrained eye.
Watch expert polishers and goldsmiths at work: See artisans seated at their workstations as they carefully shape, polish, and mount diamonds. The precision involved becomes clear as even tiny adjustments affect a stone's brilliance.
See famous diamonds and exceptional collections: Admire displays of loose diamonds and finished stones, including the patented Royal 201 diamond and a replica of the legendary Koh I Noor. The collection showcases a remarkable variety of cuts, sizes, and styles.
Access private collection rooms inside historic villas: Beyond the workshop areas, enter elegant rooms housed within historic villas. Here, display cases filled with sparkling diamonds sit among classic interiors, creating a striking contrast between heritage architecture and precious stones.
Wrapping up
Your tour ends inside the jewelry collection boutique, giving you time to browse the curated pieces at your own pace or leave the Royal Coster Diamonds factory whenever you are ready.
