Ungrouped achondrite. "NWA 13791" (Sahara, 2020) Very rare for sale — only 142 grams in the world. - 8.8 g

NWA 13791 is a rare meteorite that was classified as an unpaired achondrite in 2021, when the relevant analyses were conducted, although it was discovered a year earlier.

An ungrouped (or non-grouped) achondrite is a type of stony meteorite that, although lacking chondrules (its main characteristic), cannot be assigned to any of the currently known major groups of achondrites (such as asteroid, lunar, or Martian achondrites).

Key features

Differentiated origin: Like other achondrites, they originate from celestial bodies that have undergone differentiation processes (fusion and recrystallization), which give them a texture similar to terrestrial igneous rocks, without chondrules.

Unknown parent body: The reason they are 'disaggregated' is that the specific asteroid or parent body they originate from has not been identified, or they represent material from a single parent body from which only that type of meteorite has been found.

Unique composition: Its mineralogical and chemical makeup does not match the profiles of the established groups, suggesting a great diversity in the primitive bodies of the solar system.

Unpaired achondrites are, therefore, a very rare type of meteorites highly valued by collectors as well as the scientific community, as they represent genuine rarities still to be classified within standard meteorite classifications. Don't miss this opportunity.
