The Grimsel massif is one of the most mineral-rich areas in the Alps. Rock crystals, smoky quartz, fluorite: hidden within the Aare granite lie fissures that have fascinated gemstone hunters and scientists for centuries. Join our gemstone hunters on a journey through the kriSTALL experience. Learn how these Alpine treasures are formed and how to find them. Mineralogy has played a major role in Guttannen for centuries – as a source of income, a vocation and part of an identity that lives on to this day. On our guided tour, you’ll learn first-hand how mineralogy works, what makes a crystal find special and what it means to you.

kriSTALL is a unique, unconventional project that fits perfectly with Guttannen. This immersive experience, centred on the Rufibach family’s collection – which had long been inaccessible but never quite forgotten – was realised as a collaborative effort, by and for Guttannen. We’d be delighted to tell you how the ideas surrounding the magical crystal cosmos in the barn took shape, how the project came about, and who all contributed to making the extensive Rufibach crystal collection accessible to the general public once again. Naturally, a visit to kriSTALL Guttannen is also part of this programme.
