Found 2017 A.D.. A rare eucrite meteorite slice recorded as: Northwest Africa 11576; displayed in a Swiss membrane box, inked inscription ' NWA 11576' to one edge. 20 grams, 38 mm (76.3 grams total, 99 x 75 mm including case) (1 1/2 in. (3 7/8 x 3 in.)).

Eucrites are achondritic stony meteorites thought to have originated from the surface of the giant asteroid (or minor planet) 4 Vesta. Vesta is the second largest body in the asteroid belt, with a mean diameter of 525 kilometres. Like Earth, it has the differentiated layers of crust, mantle, and core common to rocky planets: this may mean that 4 Vesta is the remnant of a larger destroyed planet.

From North West Africa (Mali). Ex SV-Meteorites, Prague. From a Leicestershire, UK, collection. Accompanied by an original identification card. [No Reserve]
