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. It is a basaltic shergottite (NWA 2975 pairings) 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.
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.
From the Meteoritical Bulletin entry on NWA 2975 (and pairings) :
Achondrite (Martian, basaltic shergottite)
Geochemistry: Pigeonite (Fs35.2–57.6Wo12.6–16.5; FeO/MnO = 28–38) and augite (Fs27.2–41.5Wo30.8–35.2) show mottled compositional zoning. Fe-rich margins of pigeonite contain very thin (0.2–0.5 µm) orthopyroxene exsolution lamellae. Maskelynite is compositionally homogeneous An55Or1.8 in contrast to mesostasis maskelynite (An48–60Or9.2) and glasses. Melt inclusions (15–60 µm, longest dimension) in ulvöspinel have rims of Fe-rich pigeonite (Fs73.5Wo5.8), merrillite, and pyrrhotite; cores are Si-Al-K-Na-rich glass. Bulk composition: Calculated average bulk composition based on analyzed phases and their modes of three melt inclusions is: SiO2 = 70.2, Al2O3 = 8.5, TiO2 = 0.8, FeO = 2.1, MnO = 0.2, MgO = 2.35, CaO = 3.5, Na2O = 0.95, K2O = 2. 1, and P2O5 = 2.8 (all wt%) with trace amounts of NiO, CoO, and S. One melt inclusion contains only fayalite (Fa84) mantled around a core of glass (K2O = 6.4, SiO2 = 78; both wt%).
Classification: Achondrite (Martian basaltic shergottite); moderate to high shock, minimal weathering.
