The GASSAN Diamond Journey in Amsterdam is a unique experience that blends craftsmanship, history and luxury, showcasing the dazzling allure of diamonds and the brand's dedication to excellence from its core attractions to its premium services. The first stop of the journey takes you to the historic GASSAN Diamond Factory, which not only preserves traditional processing techniques but is also equipped with modern facilities. Visitors can closely watch skilled artisans transform rough diamond stones into sparkling treasures through meticulous cutting, polishing and other processes. Accompanied by professional commentary, one can also gain in‑depth insights into the brand's evolution from a small 5‑person workshop in 1945 to a world‑renowned top‑tier brand, as well as the history behind the global fame of Dutch diamond cutting. Conveniently, the factory can be reached by boat via a private berth, allowing guests to enjoy the riverside scenery along the way, making the visit enjoyable from the very start.

Next, step into the HOUSE of GASSAN, a true gathering place for luxury enthusiasts. On one side is the renowned Rolex boutique, offering a comprehensive selection of timepieces complemented by professional service. Whether you are a watch collector or an ordinary enthusiast, you are sure to find your ideal piece here. On the other side, exquisite diamond jewellery collections are on display, where unique setting techniques make every diamond shine brilliantly and fully. The classic combination of rose gold and diamonds interprets countless elegant designs, from lightweight styles suitable for daily wear to glamorous pieces for special occasions, catering to diverse needs. Each piece is a perfect fusion of art and practicality.

The Diamond Exhibition Hall is a key venue for experiencing the unique charm of diamonds. The hall displays a variety of loose polished diamonds, with the most eye‑catching being GASSAN's patented "GASSAN 121" cut diamond. Unlike the traditional 57 facets, this diamond, launched in 2005, features an increased 64 facets on the crown and pavilion, greatly enhancing light refraction and resulting in a more brilliant sparkle. It has also received recognition from the International High Diamond Organisation. Through the exhibition, visitors can intuitively understand the differences between diamonds of various cuts and clarities, and gain in‑depth knowledge of the diamond 4C standards.

For those seeking a more private and high‑quality visiting experience, the "Fashion Diamond Journey" is an excellent choice. The small group size ensures that every guest receives ample attention. A dedicated guide will lead you on an in‑depth exploration of each attraction, answering all your questions about diamonds in detail. Champagne is also provided during the journey, allowing visitors to admire diamonds and discuss craftsmanship in a light‑hearted atmosphere. Occasionally, fun interactive sessions are included, making the entire experience both enriching and relaxing, allowing you to fully appreciate the unique charm and brand warmth of GASSAN diamonds.
