Iron meteorites, the most visually intriguing of the meteorite types, come to us from large asteroids with molten cores that once orbited the sun between Mars and Jupiter. Extremely slow cooling of those cores, over millions of years, allowed nickel-iron alloys to crystallize into fantastic geometric structures known as Widmanstätten Patterns. Much like snowflakes, the pattern of every iron meteorite is unique. Such patterns are prominently displayed in these exquisite necklaces. Each piece is one-of-a-kind, like the wearer.
