about 280 million years ago lava flows and violent explosions formed one of the largest volcanic areas in the world. between the glowing lava blocks hot water created a special stone now found, millions of years later, in the „naif-valley“ above merano. it consists of the elements silicon, oxygen and traces of iron and is assigned to the family of jasper. its red-fiery veins in a rich green matrix make it a unique gemstone.
