Meteorite (Uruacu) Cross in Sterling Silver

Uruacu Meteorite cross in sterling silver     The main elemental components of octahedrite meteorites are by no means rare with the vast majority being iron and nickel (with trace amounts of other elements including gallium, germanium and iridium). It is the crystalline pattern of these meteorites (called the Widmanstätten pattern) that makes them not only rare, but also beautiful and unmistakably of cosmic origin. You see, the alternating elongated lamellar bands of iron-nickel crystals running in groups at 60 degree angles forming an octahedron crystalline lattice occurred as molten asteroid bodies cooled while they hurled through the zero gravity vacuum of space at roughly -454.75 degrees Fahrenheit, conditions which are difficult to simulate. This pattern is therefore unique to these meteorites and cannot be replicated on earth. Each meteorite has unique crystal sizes and is categorized based on the width of its lamellae. Thus, every meteorite is unique within this class of meteori
