NWA 15856 is a Polymict Eucrite found near Ouargla, Algeria, in 2020 and officially classified as an HED Achondrite. As a Eucrite, it is part of the meteorite family strongly linked to asteroid 4 Vesta, representing basaltic crustal material from an early differentiated body. The Meteoritical Bulletin records NWA 15856 as a single 530 g stone, with its main mass held by Sean Mahoney.

Specimens of NWA 15856 show a brecciated texture, with angular to sub-rounded cumulate and basaltic Eucrite clasts set within a fine-grained fragmental matrix. Minor Diogenite clasts are also present, making up less than 10 percent by volume, along with accessory phases including silica-rich glass, troilite, and iron-nickel metal. The original stone is described as having heavily weathered fusion crust over around 60 percent of its surface, with desert varnish covering the remainder.

For collectors, NWA 15856 offers a scarce and well-documented Vestan Achondrite with strong visual and scientific interest. Its Polymict Eucrite classification records impact mixing on Vesta’s crust, while its single-stone recovery and limited total mass add to its appeal. Each specimen represents ancient basaltic material from asteroid 4 Vesta, shaped by volcanic activity, impact processing, and eventual delivery to Earth.
