Beautiful FUKANG Meteorite Pendant - Jewelry
On Offer: Fukang Pallasite Meteorite Pendant - Translucent when held up to the light!
Official name: Fukang
Description: Meteorite Pendant in Sterling Silver Setting.
Fun Information: The Fukang pallasite is one of the most beautiful meteorites in the world. Discovered in China, this amazing pallasite displays large translucent green and yellow olivine crystals set into a solid iron-nickel alloy matrix.
The pallasite meteorites are part of the stoney-iron meteorites and are thought to have been liberated by cataclysmic collisions with huge planetary bodies large enough to have undergone "planetary differentiation" and had the iron and other heavy metals gravitationally drawn to the center to form a core. The pallasites represents the transition zone between the iron core and stoney mantle. As the celestial parent body of this amazing meteorite cooled, so did the liquid iron in and around the core. Olivine phenocrysts that have a higher melting point than the liquid iron-nickel they were floating in eventually got locked into the cooling and solidifying metal. So this really is jewelry forged in the heart of a planet. Specifically in the transition zone between the core and mantle of a large differentiated planetary body...we just aren't exactly certain which one!

Fukang, Xinjiang Province
Pallasite (main group)
History: An anonymous finder recovered a 1003 kg specimen near Fukang, China, in 2000. The sample was at the Tucson Gem and Mineral Show in February 2005, and seen by D. S. Lauretta of UAz. Approximately 20 kg had been removed from the main mass by the finder before the Tuscon show and the mass investigated at UAz was 983 kg. (D. S. Lauretta, D. Hill, M. Killgore, D. Della-Giustina, Y. Goreva, UAz; I. Franchi, OpenU).
Petrography and Geochemistry: Olivine: Throughout the large mass, olivines vary in shape from rounded to angular; many are fractured. They range in size from <5 mm to several cm. The main pallasite contains several regions of “massive” olivine clusters up to 11 cm in diameter with thin metal veins only a few millimeters in width. Fo86.4 with molar Fe/Mg = 0.1367, Fe/Mn = 40.37, and Ni = 0.03 wt%. Zoning was not observed for Al, Cr, Ca, Mn, or Fe typical of olivines in main-group pallasites. Metal and sulfides: Groundmass is mostly kamacite with some occurrences of kamacite mantles surrounding taenite cores, rounded taenite adjacent to kamacite, and regions of “comb plessite. ” Kamacite contains an average Ni = 6.98 wt%. Schreibersite is enclosed by wide kamacite bands and as mantles adjacent to olivines. Two populations of schreibersite are present with Ni = 26 and 35 wt% near chromite. Vermicular sulfide (troilite) is present in some olivine. Thin veins of kamacite and troilite occur inside many olivines as well. Minor phases: Euhedral chromites up to 0.5 cm, rounded whitlockite adjacent to olivine, and troilite heterogeneously distributed in thin veins. Several regions, ranging from <100 µm to several millimeters, that contain a complex mixture of olivine, low-Ca pyroxene, troilite, and whitlockite were observed adjacent to chromite. Bulk composition: Fe = 89.9 ± 0.3, Ni = 9.0 ± 0.2, P = 0.62 ± 0.02, Co = 0.51 ± 0.01 (all wt%); Ge = 41 ± 4, As = 26 ± 5, Ga = 19.1 ± 0.5, Pd = 5.1 ± 0.2, Au = 2.6 ± 0.2, (all µg/g); Ir = 43 ± 4 ng/g. Oxygen isotopes: δ18O = 2.569, δ17O = 1.179, ∆1 7O = −0.157 (all ‰).
Classification: Pallasite (main group).
Specimens: A total of 31 kg of type specimen is on deposit at UAz. M. Killgore holds a total of 31 kg. An anonymous collector holds the main mass.
