Gassan is a family-owned diamond company located in Amsterdam, Noord-Holland. Housed in a carefully restored 1879 diamond factory, Gassan operates specialized visitor experiences that showcase diamond cutting, polishing and jewelry craftsmanship. The company offers hands-on and guided tours including the Diamond Polishing Experience Tour, See Diamonds In Style Tour, Gassan Diamond Experience Tour and the Diamond & Champagne Tour.
Each experience highlights the workshop process and the unique GASSAN 121 cut. Under expert supervision, visitors can learn the fundamentals of the 4 C’s, observe craftsmen transforming rough stones into polished gems, and — in hands-on sessions — add facets to a stone and receive a certificate of completion. Several tours include champagne and exclusive access to luxury jewelry and watches, including a dedicated Rolex Boutique.
Gassan emphasizes transparency and education during every visit. Guides explain diamond terminology, grading basics and practical demonstrations without technical jargon, making complex processes accessible to both collectors and first-time visitors. The restored factory setting preserves historical character while operating with contemporary standards for safety and professionalism.
For guests seeking memorable events, the Diamond & Champagne Tour introduces playful discovery elements such as a sparkling cocktail with a hidden gem; winners receive a genuine diamond and a certificate of authenticity. All visits are designed for small groups to maintain a focused experience. Gassan serves visitors interested in gem education, bespoke jewelry and premium watch shopping, providing a trusted, informative and memorable Amsterdam diamond experience. Advanced restoration displays and transparent sourcing information further support visitor confidence today.
