Angrites are among the rarest and most scientifically important achondritic meteorites known today. Formed extremely early in the history of the Solar System, they originate from a differentiated parent body that experienced intense igneous activity within the first few million years after CAI formation. Their exceptional scarcity, combined with their fundamental scientific relevance, makes angrites highly sought after by both research institutions and advanced collectors.
These meteorites crystallized from basaltic to gabbroic magmas under highly oxidizing conditions—an unusual characteristic among achondrites. Their mineralogy is dominated by calcium-rich olivine, aluminium- and titanium-rich augite, and anorthite, often accompanied by rare accessory phases such as kirschsteinite or ulvöspinel.
Radiometric dating places angrites among the oldest known igneous rocks in the Solar System, with ages exceeding 4.56 billion years. As such, they provide a unique window into early planetary melting, differentiation, and volcanic processes on small, now-extinct planetary bodies.
Because of their extreme rarity and limited total known mass, angrites appear only sporadically on the private market. Well-documented specimens with clear provenance are particularly valued, as most known material is curated in institutional and research collections worldwide.
