This iron meteorite fell to our planet over one million years ago, originating from the core of a celestial body. Discovered in northern Sweden near the Arctic Circle, the Muonionalusta is celebrated among designers and metalsmiths for its breathtaking \u003cstrong\u003eWidmanstätten Pattern\u003c\/strong\u003e — a natural crystalline structure formed over billions of years as the meteorite slowly cooled in the vacuum of space. No two specimens are identical, making each cabochon a singular artifact of deep cosmic history.\u003c\/p\u003e\u003cp\u003eThis oval cabochon measures \u003cstrong\u003e10mm × 8mm\u003c\/strong\u003e and is calibrated for consistent setting compatibility. Each piece is etched to reveal its iconic geometric crystalline pattern and nickel-plated to protect against oxidation. Ideal for fine jewelry designers, custom jewelers, and metalsmiths seeking a genuinely rare and story-rich material for pendants, rings, earrings, and other statement pieces.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGenuine Muonionalusta iron-nickel meteorite — over one million years old\u003c\/li\u003e\n\u003cli\u003eStriking \u003cstrong\u003eWidmanstätten Pattern\u003c\/strong\u003e revealed through etching — a naturally occurring crystalline structure unique to iron meteorites\u003c\/li\u003e\n\u003cli\u003eEtched and nickel-plated for rust prevention and long-term stability\u003c\/li\u003e\n\u003cli\u003eCalibrated oval shape for consistent setting use\u003c\/li\u003e\n\u003cli\u003eEach cabochon is a one-of-a-kind piece; color, pattern, and character will vary\u003c\/li\u003e\n\u003cli\u003eSuitable for use in fine jewelry, custom metalsmithing, and collector settings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eOval\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e10mm × 8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eIron-Nickel Meteorite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePattern\u003c\/th\u003e\n\u003ctd\u003eWidmanstätten Pattern\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTreatment\u003c\/th\u003e\n\u003ctd\u003eEtched and nickel-plated for rust prevention\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHardness\u003c\/th\u003e\n\u003ctd\u003eNot rated on the Mohs scale; handle with care\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eMuonionalusta, Sweden\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDue to the natural origin of this material, each cabochon will display unique patterning, inclusions, and character — exact appearance will vary from images shown.\u003c\/li\u003e\n\u003cli\u003eAvoid prolonged contact with moisture; clean gently with a dry cloth to preserve the nickel plating and prevent oxidation.\u003c\/li\u003e\n\u003cli\u003eNot rated on the Mohs hardness scale — exercise appropriate care during setting and wear.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":46393137823958,"sku":"935-038","price":64.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/935-038_thumb_63e85503-1ae4-4f75-a695-edee914063ed.jpg?v=1735348354","url":"https:\/\/www.ottofrei.com\/fr\/products\/muonionalusta-meteorite-cabochon-oval-10mm-x-8mm","provider":"Otto Frei","version":"1.0","type":"link"}
