The Bollwerk jewelry workshop is nestled on the first floor of the boutique. Designed from start to finish in the purest tradition of French High Jewelry, Bollwerk creations are the perfect combination of irreplaceable and highly specialized crafts. Jewelers, gem setters, and polishers work together in perfect harmony, creating a true team effort. Everything is made in-house, without any intermediaries, with a commitment to preserving traditional craftsmanship. From casting and cutting with a jeweler's saw to setting, polishing, and engraving, the entire creative process is done by hand by the Bollwerk team. This unique approach, characteristic of the Mulhouse-based jewelry house, attracts clients from Paris to Luxembourg, Switzerland, and the Persian Gulf. 

Today, the company offers services for transforming, repairing, and maintaining jewelry, checking settings, and restoring antique pieces. The idea? To reimagine an inherited gemstone or an outdated piece of jewelry, giving it a new lease on life. This comprehensive and varied offering remains the preserve of the finest jewelers. A title to which Bijouterie du Bollwerk can certainly lay claim, being one of the last French houses to possess its own design workshop.
