Meteorite QuadGrooveThe ring shown is a flat profile titanium ring with an inlay of genuine Gibeon Meteorite that fell to Earth in prehistory. It has the four signature grooves that help define the look. The meteorite is the iron nickel core of an asteroid estimated to be about 4. 6 billion years old! The government of Namibia has stopped export of the meteorite, so it will become more rare as the years go by. This is a very classy look.
