Here's a chance to own a large fragment of a rock from the Moon for an amazing price!  One of the largest caches of lunar meteorites ever discovered has allowed prices to remain the lowest in history, so don't miss this opportunity--prices will only go up from here!  This is a beautiful 9.3 gram fragment that, although has had most of the Sahara sand/soil removed, still has some hints of it remaining!

Physical characteristics: Many identical appearing pieces, no fusion crust. A saw cut reveals a fragmental breccia with numerous white feldspathic clasts set in a dark-gray ground mass.

Petrography: (C. Agee, UNM) This meteorite consists of primarily feldspathic clasts and shock melt with lesser amounts of fragmental pyroxene and olivine.
