GRANADA was established in 2015 in a beautiful 1910 arts-and-crafts style house in downtown Tucson, located on the now-infamous Granada Avenue. The name "GRANADA" is not only a reflection of its place of origin, but also an homage to the world’s largest gem, mineral, and fossil show, and everything it represents, both in business and in life, for its founders.

Alison and Rüdiger first met in Tucson during the Gem Show in 2009.
Their diverse backgrounds, shared interests, and deep family ties to the world of natural history
set them on a path of both personal and professional partnership.

With the ambition to create a leading platform for natural history and design, GRANADA has since become synonymous with exceptional quality and a broad, interdisciplinary scope. Its universe reflects the full spectrum of what the Tucson Gem, Mineral and Fossil Show represents, spanning geological rarities, natural history objects, art, design, and high jewelry.

Decades of collecting, combined with close relationships within the trade, have resulted in a diverse and comprehensive collection of fossils, meteorites, gemstones, and minerals. Direct access to excavation sites, together with an extensive global network, allows GRANADA to operate at the source of each curated object. This ensures the highest standards of quality, provenance, and authenticity, while maintaining a strong commitment to responsible sourcing.

GRANADA works in close collaboration with specialists in mineralogy, gemology, and paleontology, as well as with scientists and museum curators worldwide. The platform advises, supplies, and collaborates with collectors, auction houses, designers, and institutions, while also contributing to exhibitions and scientific projects that promote knowledge, curiosity, and a deeper understanding of the natural world. GRANADA has participated in international platforms such as Art Basel Miami, TEFAF Maastricht, and Design Hotel Arena in Copenhagen.

In 2019, GRANADA joined forces with close friend and renowned Belgian jewelry designer Jochen Leën. Together, we have steadily elevated the scope and reach of GRANADA, expanding into the European market, branching into top-tier hospitality, and forging new partnerships along the way. This evolution led to the establishment of a home base at the prestigious Hotel La Butte aux Bois in Lanaken, Belgium. From here, we continue to develop and transform GRANADA, always striving to push boundaries and pursue our boldest ambitions.
