Stony-iron Meteorite: Consisting of planet core and mantle materials, peridot olivine crystals in an iron-nickel matrix, there are only 61 Pallasites known. This is a small section of the first ever found: in 1772 German naturalist Peter Pallas studied a 680kg specimen found near Krasnoyarsk in the mountains of Siberia. Our small section was given to us by the antiquarian and traveller Sir Richard Colt Hoare, 2nd Baronet FRS (1758 – 1838).
