Stephanie Zwerner and Steffen Dettmann have developed their passion for minerals and interior design into the extraordinary business concept Kristallkontor.
With the new opening, the two Lübeckers showcase a significant innovation in conceptual spatial design. For the first time, crystals, which were previously seen as collector's items, are presented holistically in a living concept and offered for sale. White-framed, antique furniture from Scandinavia forms the basis of the interior design, where decorative minerals are used as style elements. Friendly artists refine some of the rare stones into art objects and wall decorations. In the context of an individually emphasized furnishing style, the solitaires make a good impression. In addition to decorative minerals, bowls and lights made of crystals are part of the portfolio.
The usability of these natural beauties is important to both Lübeckers. "The crystals are a daily reward for the eye!" says Steffen Dettmann, who selects the stones with geological expertise. The minimalist calm that the light furniture radiates is elegantly accentuated by decorative minerals in friendly pastel tones. The new living style has been aptly named by the two Lübeckers with a neologism: Mineralistic. The aesthetic harmony of this new furnishing style delights interior designers, decorators, and home enthusiasts. The offering in Lübeck's Old Town is complemented by unique jewelry pieces and small treasures that are attractive not only to tourists. Owner Stephanie Zwerner emphasizes that all natural objects and furniture are pre-selected with a keen sense of style to provide customers with a special and inspiring atmosphere.
"The extraordinary individual pieces made of decorative minerals and Danish vintage furniture have been brought together with the fundamental idea of living with more attention to detail and thus experiencing the lightness of being," says the creative businesswoman. The store is located in the historic Engelsgrube, not far from the drawbridge at the Museum Harbor.
