In the heart of Amsterdam’s vibrant Noord-Holland district lies an unexpected adventure beyond nature’s trails: the See Diamonds In Style Tour by Gassan. This exclusive 45-minute journey takes visitors inside one of the world’s premier diamond workshops, where centuries-old craftsmanship meets modern precision. Located at Nieuwe Uilenburgerstraat 173-175, the Gassan facility stands as a cornerstone of Amsterdam’s rich heritage in diamond artistry, a tradition woven into the city’s fabric since the Dutch Golden Age.
Step beyond the typical tour to witness diamond cutting as a precise, technical art form. You’ll discover the nuances behind the 4 C’s—carat, color, clarity, and cut—and get an insider look at the Gassan 121, a revolutionary diamond cut developed by the company that elevates brilliance and fire. A personal guide leads your small group through the workshop’s inner workings, revealing the meticulous steps that transform rough stones into exquisite gems.
The experience pairs well with sipping champagne, reflecting the luxury and care poured into each facet and finishing touch. After absorbing the craft, guests can browse Gassan’s curated collection of high-end jewelry and watches, featuring renowned brands and unique designs.
While Amsterdam often draws adventurers for its canals and urban charm, Gassan adds a refined cultural layer. This tour reveals the link between natural geological marvels—diamonds formed deep within the Earth—and human creativity expressed in cut and setting. It’s a distinct blend of science, art, and luxury that complements outdoor adventurers’ appreciation of fine detail and elemental beauty.
Whether you’re drawn by geology, craftsmanship, or simply a taste for something different in the city, Gassan’s tour offers a polished perspective on what makes Amsterdam a standout destination beyond the beaten path.
