The meteorite<\/p>\n

As old as the solar system<\/h1>\n

Every Rivus dial began as part of the molten core of a small body that never became a planet. It formed some 4.5 billion years ago and was later shattered in a collision.<\/p>\n <\/div>\n<\/section>\n\n\n

    Chapter one<\/p>\n

    A core without a planet<\/h2>\n

    In the early solar system, small planetary bodies melted and separated into layers, just as Earth did, with iron sinking to the centre. When one of these bodies was destroyed in a collision, fragments of its nickel-iron core were thrown into space, where they drifted for billions of years. One of them was on a very long journey to northern Sweden.<\/p>\n <\/div>\n

    \n

    Chapter two<\/p>\n

    The fall at Muonionalusta<\/h2>\n

    Roughly a million years ago the fragment struck what is now Swedish Lapland, near the Muonio river. Ice ages buried and scattered the pieces; the first was found in 1906. The meteorite was named Muonionalusta and classified as a fine octahedrite (type IVA), prized for the beauty of its internal structure.<\/p>\n <\/div>\n

    \n

    Chapter three<\/p>\n

    The pattern no one can forge<\/h2>\n

    Inside the iron, two nickel-iron alloys, kamacite and taenite, crystallised into interlocking bands as the core cooled, roughly one degree every thousand years. The result is the Widmanst\u00e4tten pattern, a geometric lattice that forms only over millions of years in space. It cannot be manufactured or copied. When a polished slice is etched with acid, the pattern appears, different in every cut. That slice becomes a dial.<\/p>\n

    1 \u00b0C per 1,000 years<\/b>That is how slowly the core cooled while the pattern of your dial was forming.<\/span><\/p>\n <\/div>\n <\/div>\n<\/section>\n\n\n\n

    From meteorite to certificate<\/h2>\n

    Our dials are made from Muonionalusta with documented origin. Every dial comes with a certificate of authenticity from the Museum of Meteorites, a member of the International Meteorite Collectors Association (IMCA).<\/p>\n
