Behind every crystal found is a story of passion. It is the story of the radiator who sought and found him. Select the stone and read what the finder wrote in the “Schweizer Strahler”…

Brookit – Peter Amacher

Peter Amacher has a passion for small, colourful minerals. In 1975, together with fellow radiators, he found a fissure system with brookite crystals at the Chärstellenbach in Uri. In the years that followed, he was drawn there again and again: ’62 radiator days I worked there, searched… and found…’

Anatase – Patrik Heule

It sounds like a fairy tale: under the uprooted roots of a fallen tree, Patrick Heule first found small rock crystals in the summer of 2012 in Val Punteglias (Grisons). When he took a closer look at them, he saw: they were covered with beautiful dark anatase.

Smoky Quartz – Yves Donnet-Monay

Yves Donnet-Monay has been searching for minerals in the Upper Valais mountains for years. In August 2011, when he was walking with a colleague on an alpine pasture above Brig, searching the slopes with his eyes, he suddenly had a strange feeling in his stomach: ‘I knew there was something waiting for me up there on that ridge…’. And indeed…

Cölestin – Stefan Bättig

Stefan Bättig is a passionate Jura hiker. These mountains are just closer to where I live and easier to reach. When he heard about celestine finds in the Jura a few years ago, it stuck with him. He searched the quarries in the area and found what he was looking for…


Actually, Heinz Moser was a typical climber. Four thousand metre peaks he wanted to conquer. But years ago, when he found small, shiny black stones on the ground while climbing the Rimpfischhorn near Zermatt, he was captivated. He had found black grenade and has been a passionate blaster ever since….

Armenite – Martin Andres

Even as a boy, Martin Andres was out and about in the mountains with his father, looking for the beautiful stones. He also travelled a lot in books. He wanted to know and understand what he found there. On one of his first solo walks, he made a spectacular first find: Armenite on the Wasenhorn.



define the concept of beauty here. From the Stone Age to the present day, the crystals found in nature or painstakingly brought out by “radiators” have fascinated us. Terms such as “frozen ice”, which originated with the Greeks, to “Milanese ware” in the Middle Ages, describe only part of this unique natural beauty.


building blocks have arranged themselves in a regular building structure. The emergence of these different-looking crystals, which, however, in the final analysis can always be traced back to a uniform structure, inspires the radiator and teaches him respect for nature and the environment.


of time, high pressure and high temperatures in the earth’s interior with certain liquids, fissures could form and then the crystals in their cavity. This art in nature is unique and inspires everyone who engages with it.


Of the many minerals, rock crystal is probably the most fascinating with its brilliance. Shine and clarity often make it shine mysteriously. This is why it is also called the ‘stone of light’. It is something mysterious and makes us search for words to name the intangible.


Even if each crystal looks quite unique, they are all built according to their inherent law, according to their crystal lattice. This regularity in combination with the changing environment gives the crystal its uniqueness and its beauty. In the crystal, the law becomes visible in its beauty.


Despite strict regularity, however, crystals are found again and again in new forms. The changing environmental conditions make this possible. There are also around 4500 different minerals. The interplay of minerals in a cleft is what makes a stage so special and shows the diversity of the crystal world.



Radiators are called the crystal and mineral seekers, especially in Switzerland. These crystal seekers have been known since Roman times. Through exhibited finds, the spotlights also contributed significantly to the understanding of the Alps and their geology!


Passion gives the power. Those who search for crystals often have to walk long distances, have to open the rock with hammer and chisel before they can retrieve the beautiful minerals from the crevice. Passion is the driving force behind this achievement.


Passion alone is not enough. The spotlight must be able to read the rock. He must know the signs that indicate a rift. This knowledge is often guarded by the radiators like the secret to success.


The radiators have developed special tools to search for and recover the crystals. The blasting stick to remove larger boulders; the dredger to carefully dig the material out of the crevice. The equipment also includes: hammer and chisel, mountain pick, magnifying glass and, above all, good shoes.


Those who use their tools too greedily often destroy what they are looking for, the crystals, already in the cleft. The craft of the radiator therefore also involves patience, a great deal of care and love for nature.


The Code of Honour of the Swiss Association of Blasters, Mineral and Fossil Collectors (SVSMF) regulates blasting and obliges blasters to behave correctly in nature. A cleft must be left clean after it has been exploited. If a gap is occupied with tools, other spotlights must keep their hands off it.



An iron about one metre long, bent at right angles on one side and forged as a flat or pointed chisel on the other side, used to loosen lumps of rock (pry bar).


Is a must on the glaciers, but mainly serves as a tool for removing debris from rock sets or digging under the turf.


Is a tool made of metal (often copper, because of its pliability). Es ist auf einer Seite abgewinkelt und auf der anderen Seite oft mit einer Schaufel versehen. This tool is used to carefully extract the crystals in the fissure.


Hammer, chisel and point iron are the main tools of the radiators. With this, rocks are split off, crystals are pointed out and crystal steps are formatted to their size.


The magnifying glass is also part of the spotlight equipment. This makes it possible to determine already in the field whether valuable small minerals are present and whether it is worthwhile to carry the stones down into the valley.


Spotlights often move in sloping and dangerous terrain. Good shoes and crampons are half the life insurance.
