Like lunar meteorites these meteorites are among the most thought-after and rarest on the market. Our newly classified Martian meteorites to the collector's delight. The NWA 4766(Northwest Africa 4766) is a martian meteorite; Achondrite (Martian, shergottite); minimal weathering, high shock grade based on complete transformation of plagioclase to maskelynite. The original recovered material was a shiny, dark, 83 g fusion-crusted stone in three pieces. Minimal weathering. Interior shows abundant maskelynite and shock melt vein. Shergottites are pieces of the crustal mantle of the planet Mars that were blown into orbit by an enormous meteorite impact hitting the red planet. This meteorite spent ages in space before it was caught by the earth's gravity and landed in the Libyan desert.
The marsrock comes in a plastic box and is about 3 mm long which is fairly large. The box is 2x1 inch in size and can be opened, of course, to touch your piece of mars. A PERFECT AND UNUSUAL GIFT IDEA!
