Originally found in 2019, this ancient denizen of our early solar system was found in the Saharan Desert an sold through a dealer in Assamakka, Niger to another in Poland, and I bought it from there.
NWA 12675 is a carbonaceous chondrite (CV3) with chondrules (mean diameter about 1 mm; up to 3 mm sized), CAIs, and olivine amoeboids all set into a fine-grained almost black matrix.

carbonaceous chondrite: A major class of chondrites that mostly have Mg/Si ratios near the solar value and oxygen isotope compositions that plot below the terrestrial fractionation line.
CV group: The Vigarano (CV) chemical group of carbonaceous chondrites, distinguished by large (mm-sized) chondrules, many of which are surrounded by igneous rims, large refractory inclusions and abundant matrix (40 vol%).
type 3: Designates chondrites that are characterized by abundant chondrules, low degrees of aqueous alteration, and unequilibrated mineral assemblages. Many of the low-Ca pyroxene grains are monoclinic and exhibit polysynthetic twinning.
