The Fukang pallasite contains large, gem quality olivine, or peridot, in a nickel-iron matrix. Olivines vary in shape from rounded to angular, many are fractured and they range in size from less than five millimetres to several centimetres. The main mass contains several regions of massive olivine clusters up to eleven centimetres (4.3 inches) in diameter with thin metal veins. Fo86.4 with molar Fe/Mg = 0.1367, Fe/Mn = 40.37, and Ni = 0.03 wt%. The metal matrix is mostly kamacite with an average Nickel contents of 6.98 wt%. Vermicular sulfide (troilite) is present in some olivine.
Oxygen isotopes: δ18O 2.569 ‰, δ17O 1.179 ‰, ∆1 7O = −0.157 ‰.
A section weighing a total of 31 kilograms (68 lb; 4.9 st) of type specimen is on deposit at the University of Arizona. Marvin Killgore holds an additional section of the same total amount. An anonymous collector[who?] holds the balance of the main mass.
In April 2008, Bonhams offered the main mass for auction at their Manhattan auction. Bonhams expected to fetch US$2,000,000, but the lot remained unsold. A "window" area of 19 by 36 inches (480 mm × 910 mm) was cut and polished to provide a view into the gem areas of the meteorite.
