The 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.
