The ring shown is a titanium ring with an inlay of genuine Gibeon Meteorite that fell to Earth in prehistory.  The meteorite was discovered in Namibia in South Africa in 1838.  It has a unique crystalline grain structure called Widmanstatten lines that were caused by the meteorite slowly cooling over millions of years as it hurtled through space.  It is estimated to be about 4.6 billion years old, when the Earth had not yet fully formed!  The government of Namibia has stopped export of the meteorite, so it will become more rare as the years go by.  It's Space Age versus the Age of Space in perfect contrast.  Nothing says Forever like something born from exploded star stuff.
