Several meteoritic stones, classified as L6 chondrite, which fell on 10 February 1853 near Agrigento (at that time, Agrigento was called Girgenti). The total recovred mass is about 18 kg.

A mineralogical and chemical study performed on the largest mass (8750 g) of the Girgenti meteorite, from the collection of the Smithsonian Institution, Washington, D.C., showed that its mineralogical composition is: forsterite (Fa24–25), enstatite (Fs21 –22), plagioclase (An12), "maskelynite", whitlockite, nickel-iron alloys (abundant taenite and scarce kamacite), troilite, chromite, and ilmenite. Girgenti is a severly metamorphosed stone, whose total iron content (23.5%) is somewhat higher than the average for hypersthene chondrites (Levi-Donati & Jarosevich, 1972).
