NWA 13758 is a rare Rumuruti R3 Chondrite purchased in Algeria in 2017, after a large group of similar stones was reportedly found together in the Adrar region. Rumuruti Chondrites are an uncommon class of meteorite, distinct from Ordinary Chondrites, and are recognised for their oxidised chemistry and low abundance of metallic iron. The type 3 classification indicates relatively primitive material, preserving early solar system textures with limited thermal alteration.

NWA 13758 specimens typically show a dark exterior, often naturally sandblasted from desert exposure, with interiors that can reveal a brecciated structure. Prepared pieces may display contrasting grey and brownish-orange lithologies, along with abundant visible chondrules. As is typical for Rumuruti Chondrites, NWA 13758 has very little free metal, with iron largely present in oxidised mineral phases rather than metallic grains.

Studying NWA 13758 provides valuable insight into the diversity of primitive Chondrite parent bodies and the unusual oxidation conditions present in parts of the early solar system. Its R3 classification, brecciated texture, and relative rarity make it especially desirable for collectors focused on uncommon Chondrite groups. Each specimen represents ancient asteroid material formed over 4.5 billion years ago, preserving a less common pathway in early solar system history.
