Extremely rare NWA 6963 Martian meteorite slice, found in the deserts of Northwest Africa. The partial slice weighs 4 grams and measures approximately 37 mm x 33 mm x 1 mm, and is displayed in a small membrane display frame. Martian meteorites are believed to have been blasted off the surface of Mars by other meteorite impacts, and eventually landed on Earth. Accompanied by a certificate of authenticity signed by Geoff Notkin of Aerolite Meteorites Inc. and the TV show Meteorite Men, as well as a specimen identification card. As an actual piece of the planet Mars, this is an enormously desirable specimen.
