Description: On Offer: 9.13 gram triangular prism shaped piece of a lunar meteorite, of the type feldspathic breccia. All sides but one have been polished to allow for an exceptional interior view of the clasts and matrix. The side that was not polished was left as it was found, with only minor cleaning.Dimensions: 26mm x 18mmOfficial name: NWA 14041Type: Lunar Feldspathic BrecciaYear Found: 2021Country: MaliThe story: Our Moon takes a lot of hits. This is evidenced by the millions of craters that cover the moon's surface. Thankfully the bombardments have slowed down considerably in the last few hundred thousand years, but they still do occur from time to time. Lunar meteorites are material ejected from our Moon's surface when it gets hit by a meteorite. If the impact has enough energy, some of the ejecta gets thrown so far it escapes the Moon's gravity becoming meteoroids hurtling through space. Some of those lunar meteoroids have the potential to eventually fall into Earth's gravity well and go screaming through the atmosphere to hit the surface. Once they hit the Earth's surface, they earn the designation of being a meteorite. Much later, perhaps thousands of years later, an even smaller fraction of the meteorites that didn't fall into the oceans or onto unrecoverable terrain, are recovered by nomads and others who happen to find them. Nothing short of miraculous odds. To describe them as rare, is perhaps an understatement.Description: An amazing 9.13 gram lunar feldspathic breccia meteorite triangular piece. The NWA 14041 lunar meteorite is a beautiful brecciated lunar meteorite, with a vey complex interior in comparison with many feldspathic breccia.
