This unisex pendant contains a genuine sample of the planet Mars! - this Martian meteorite was recovered from a remote area of the Saharan Desert in Algeria. The meteorite is a shergottite (NWA 7397) and whose chemical signatures match the NASA Pathfinder rover data. The pendant has a 2mm hole and is ready to hang on a necklace of your choice - chain not included. The metal bail is sterling silver plated. This makes an "out of this world" gift!
Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing a pendant like the one shown. Your purchase will include a labeled gemjar for safe storage and an info-sheet about Martian meteorites.
From the Meteoritical Bulletin entry on NWA 7397 :
Northwest Africa 7397 (NWA 7397)
Purchased: 2012 Jun
Classification: Martian meteorite (Shergottite)
Physical characteristics: A 2130 g, partially covered in fusion crust. Interior larger ovoid crystals in a finer grained matrix.
Petrography: (A. Irving and S. Kuehner, UWS) Large oikocrysts (up to 1.5 cm across) of low-Ca pyroxene enclose multiple chadacrysts of olivine and Cr-rich chromite. Relatively equigranular domains between oikocrysts are composed of low-Ca and high-Ca pyroxene (showing very limited compositional zoning), maskleynite and olivine with accessory merrillite, Ti-chromite, pyrrhotite and ilmenite (with associated grains of baddeleyite up to 10 μm across). Olivine contains sparse melt inclusions composed of K-Na-Al-Si-rich glass surrounded by characteristic post-shock radial expansion microfractures.
Classification: Martian (shergottite, poikilitic).
