At the time of its discovery in 2007, the lunar meteorite Northwest Africa 5000 was the largest one ever found. Now you can own a sizable chunk. This piece of the meteorite is one of only seven complete slices in the world and contains chunks of 4.5 billion-year-old metal. It's believed to have sat in the Sahara for over one thousand years, giving it time to acclimate to the Earth and removing the need for overly delicate care. Known as "The Perigee," it's roughly 9.5" x 8.5", 0.3" thick, weighs about 1.5 lbs., and with the other six slices now in the hands of just four wealthy businessmen, it's the last chance to get a slice directly from the source.
