About Us

In December 1970, Freia and Christian Weise, together with Hermi and Hannes Keilmann, founded Kristalldruse, a mineral store in Munich Schwabing. In the assortment were primarily self-found minerals from Germany and the Alps. The strongly increasing general interest in minerals and fossils led to the joint foundation of Mineralientage München (Now known as the Munich–Show) in 1972.


In 1974 Christian Weise decided to devote himself full-time to trade minerals and gemstones. Thereupon he ended his scientific career as a geophysicist and retired from the organization of the Mineralientage (Munich–Show).

In the same year, he published a book about mineral prospecting in the province of Salzburg and Tyrol, thus laying the foundation for the Christian Weise publishing house and the monthly magazine Lapis. 

Since the 1990s, the second generation, Tobias Weise has also been active in the company, whose management he took in 2017.


In 2017, the Kristalldruse store was sold, and is now operated by the Munich goldsmith and jeweler family Bleiholder. 


Already since October 1981, Christian Weise Verlag has operated a mail order business for minerals, the "Kristalldruse Mineralienversand", a forerunner of today's mineral - online stores. developed from the "Kristalldruse Mineralienversand" and has been the publisher's own platform for the trade of minerals and equipment for many years, with the aspiration of fair pricing and a wide range of products.
