This meteorite wedding band I made for my own wedding.
It's made from high grade pieces of Gibeon Meteorite. The Gibeon is a fine octahedrite iron meteorite which flamed into our atmosphere as a visible star-like streak an estimated 30,000 years ago, landing in what is present day Namibia. Prior to this, the Gibeon meteorite traveled through space for over four billion years before it was finally trapped by the Earth's gravitational field and pulled to earth as a fire ball. It is composed primarily of various alloys of iron and nickel, as well as a number of extremely rare trace elements. It was derived from the core of an extinct planet that was blown apart billions of years ago during the formation of our solar system by a catastrophic impact event. The beautiful crystalline patterns within Gibeon meteorites are known as "Widmanstatten patterns", and are unique to meteorites.
