Exceeded our expectations and we learned a lot
My husband and I signed up for the Diamond Experience tour while we were in Amsterdam. It far exceeded our expectations and we learned quite a bit. We met the diamond polisher who holds the Guinness Book of Records for the smallest faceted diamond. We also received an insightful education about faceted diamonds and the difference between natural and lab-grown diamonds. Our tour guide, Anas, couldn't have been more generous with his time and answered the multitude of questions we had. He was an outstanding representative for Royal Coster Diamonds.

Why this scores 75
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Amsterdam: Diamond Experience at Oldest Diamond Factory: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Amsterdam.
How much does Amsterdam: Diamond Experience at Oldest Diamond Factory cost?
+
Prices start at $22 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Amsterdam usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Amsterdam: Diamond Experience at Oldest Diamond Factory take?
+
Plan for about 0.8 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Amsterdam is not rushed.
Is Amsterdam: Diamond Experience at Oldest Diamond Factory worth it?
+
It holds an Outty Ranking of 75 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.9/5 across 46 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Amsterdam, and how flexible the cancellation terms are.
Can I cancel or reschedule Amsterdam: Diamond Experience at Oldest Diamond Factory?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Amsterdam: Diamond Experience at Oldest Diamond Factory suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 0.8-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Amsterdam: Diamond Experience at Oldest Diamond Factory?
+
Around 16 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Amsterdam can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Amsterdam and add a light layer if any part of the 0.8-hour experience runs outdoors or after sunset.
Where does Amsterdam: Diamond Experience at Oldest Diamond Factory start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Amsterdam within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Amsterdam?
+
On Outty we rank every Amsterdam experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Amsterdam Food and Cultural Tour with 10 Tastings, Amsterdam Canal Cruise with Local Guide and Small Group, Amsterdam 90 minutes Canal Cruise with bar and snacks on board.. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Amsterdam?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Amsterdam?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
