Explore GASSAN’s diamond factory in North Holland with a guided tour, champagne, and a peek at luxury watches—perfect for jewelry lovers and curious travelers.

This review takes a close look at the See Diamonds In Style Tour offered by GASSAN in North Holland. For just $19 per person, travelers get a 1-hour guided glimpse into the fascinating process of diamond polishing, along with some luxury indulgences like champagne and access to a Rolex boutique. It’s a compact experience that promises a taste of Dutch craftsmanship and elegance without breaking the bank.
What really makes this tour stand out is the chance to see GASSAN’s iconic factory, a beautifully restored steam-driven building that’s steeped in history. The small-group format ensures an intimate setting, perfect for asking questions and getting personalized insights. One thing to keep in mind is that this isn’t a deep-dive “how-to” experience—more of a curated, sparkling overview of the industry’s highlights and innovations.
This is ideal for jewelry enthusiasts, those interested in luxury watches, or anyone curious about the blitzing world of diamonds. However, if you’re after a detailed lesson on diamond cutting or a hands-on workshop, this might feel a bit too brief. Still, for the value and the exclusive feel, it’s a memorable choice for a quick dose of glittering glamour.

GASSAN’s factory is a beautifully restored building that combines industrial heritage with modern luxury. Walking through its historic steam-driven machinery, you’ll immediately feel part of a unique slice of North Holland’s past. The atmosphere is both educational and exclusive, especially as the tour size is limited, making it feel more like a private viewing than a large, generic event.
The tour begins with a friendly guide greeting you at reception, after which you’re led inside to explore the factory’s different sections. The guide, often an expert familiar with the intricacies of diamond craftsmanship, walks you through the polishing process—a part of diamond creation that’s often hidden from outsiders. You’ll see the high-tech machinery and learn why GASSAN’s 121 cut is revolutionary, offering a new standard in brilliance and beauty.
A highlight is the explanation of the “4 Cs”—carat, color, clarity, and cut—fundamental concepts that influence a diamond’s value and appeal. Visitors often find these insights invaluable if they’re considering purchasing jewelry or watches later in the showroom. The guide may also demonstrate the diamond polishing process, making it easier to appreciate the craftsmanship behind each sparkling gem.
Following the factory tour, you’re invited to the showroom for a personal shopping experience. Here, you can browse a wide array of jewelry and watches. It’s worth noting that diamonds are not included in the tour, so if you’re hoping to buy one, be prepared for additional costs. However, the showroom features items from some of the most prestigious brands, including watches from Rolex, giving you a glimpse of the luxury market.
Guests consistently appreciate the opportunity to enjoy a glass of sparkling champagne while browsing—a touch of elegance that elevates the experience. One reviewer noted that the guide, Isa, took plenty of time to answer questions and made the visit feel more personalized and memorable.
Many reviews praise the knowledgeable guides, who make complex topics accessible and engaging. For instance, one traveler mentioned that Isa explained everything clearly, making the tour more than just a sales pitch. Similarly, Ms. Silvia received compliments for her engaging presentation, which combined technical insights with approachable storytelling. This level of expertise makes the tour suitable for both novices and those with some background in jewelry or watches.
The visit to the in-house Rolex boutique is a real treat for luxury watch lovers. You’re given a chance to see high-end timepieces up-close—a rare opportunity, especially in a factory setting. While you can’t purchase watches directly during the tour, simply viewing these pieces adds a layer of exclusivity.
The 1-hour duration is tight but packed with enough content to satisfy most curiosity. The tour departs every day at 2 PM, making it an easy afternoon activity. The small group format ensures that interactions are more personal, but it’s also important to book in advance to secure a spot.
The price of $19 is quite reasonable considering the insights and access provided. However, it’s worth mentioning that diamonds are not included in the tour—so if you’re looking to buy, you should budget separately.
This experience suits jewelry lovers, luxury watch enthusiasts, and curious travelers wanting a behind-the-scenes look at diamond craftsmanship. It’s particularly ideal if you appreciate small-group, personalized tours and want to combine a cultural landmark with a touch of luxury.
If you’re hoping for a detailed workshop or hands-on experience, you might find this tour a bit limited in scope. But if your goal is to understand the basics of diamond cutting and see a historic factory, it hits the mark.

The See Diamonds In Style Tour offers a compact yet rich overview of what makes GASSAN a renowned name in the diamond world. The combination of historic charm, expert guides, and luxurious shopping makes it a worthwhile stop for those interested in jewelry, watches, or simply wanting to see a different side of North Holland.
The value for money is compelling, especially given the intimate setting and insider knowledge you gain. While it’s not a deep-dive into diamond cutting techniques or a workshop, it’s a well-curated experience that balances education with indulgence.
To sum it up, this tour is best for travelers who want a stylish, memorable glimpse into the diamond industry combined with a touch of luxury and history. Whether you’re considering a purchase, chasing unique local experiences, or just love shiny things, you’ll likely find this tour both enjoyable and worthwhile.
