Jbilet Winselwan is a CM2 Carbonaceous Chondrite found near Smara in Western Sahara on 24 May 2013. It was reported by a local meteorite hunter shortly afterwards, and its proximity to Smara led to many searches in the area during the summer of 2013. With a total known mass of around 6 kg, Jbilet Winselwan is a significant Carbonaceous Chondrite find, offering a relatively large amount of primitive CM material compared with many rarer witnessed falls.

Jbilet Winselwan specimens are typically dark, fine-grained, and fragile, consistent with CM2 material that has experienced aqueous alteration on its parent body. It contains chondrules, type I and type II fragments, and hydrated minerals, with chondrules reported up to around 1.2 mm across. Its low shock stage and low weathering grade make it especially valuable, as the material is comparatively well preserved despite being a desert find.

Studying Jbilet Winselwan provides valuable insight into water-altered Carbonaceous material, C-type asteroid regolith, and primitive solar system chemistry. It has been discussed as an analogue for C-type asteroid sample-return missions, including Hayabusa2, because of its composition and preservation. For collectors, Jbilet Winselwan offers an important and accessible CM2 Carbonaceous Chondrite with strong scientific relevance, recognised provenance, and a clear connection to some of the most primitive material in the solar system.
