Moon Rock (NWA 10203): Lunar (moon) Meteorites, much like their Martian counterparts, are among the most popular and sought-after meteorites on the market! The total weight of lunar meteorites ever found is incredibly low compared to usual meteorites which makes them very rare. NWA 10823 is one of the latest, and most impressive meteorites that we have available.
Mars Rock (NWA 6963): These amazing, large Martian Meteorites are among the most sought-after and rarest on the market. Our newly classified Martian meteorites, much to the collector’s delight, belong to the most aesthetic and freshest shergottites, which ever were made available. The designation for this particular mars rock is ''NWA 6963'' and is one of the most beautiful pieces we have ever seen.

About Your Moon Meteorite:
Moon Meteorite Designation: NWA 10203
Physical characteristics: Twenty-seven identically appearing pieces reportedly found together. Irregular exterior, no fusion crust. A saw cut reveals a polymict breccia with numerous fragmental light and dark clasts. Petrography: (C. Agee, UNM) This polymict breccia has at least four distinct lithologies. 1) unbrecciated olivine gabbro with zoned clinopyroxene (~75%), acicular, plumose plagioclase (~15%), olivine (~5%), and minor titanomagnetite; 2) fragmental anorthositic gabbro breccia with ~75% plagioclase; 3) fragmental gabbroic breccia with approximately equal proportions of plagioclase, pyroxene and olivine; 4) shock melt veins and pools, some of which are vesicular. Accessory FeNi-metal, silica, ilmenite, troilite, chromite, and phosphate were observed in the fragmental breccias.
Geochemistry: (C. Agee and N. Muttik, UNM) Olivine gabbro: olivine Fa52.9.8±7.1, Fe/Mn=100±12, n=6; clinopyroxene Fs31.1±15.8Wo22.1±7.6, Fe/Mn=41±10, n=7; plagioclase An89.9±3.8Ab8.9±3.4Or1.1±0.8, n=3; anorthositic gabbro breccia: olivine Fa30.6±3.0, Fe/Mn=104±7, n=21; clinopyroxene Fs39.4±15.8Wo21.7±10.9, Fe/Mn=66±11, n=21; plagioclase An96.2±0.8Ab3.5±0.8Or0.2±0.1, n=6; gabbroic breccia: olivine Fa40.3±2.9, Fe/Mn=98±5, n=6; clinopyroxene Fs35.4±14.3Wo23.3±10.0, Fe/Mn=63±10, n=9; plagioclase An93.0±1.6Ab6.6±1.6Or0.4±0.1, n=4; Shock melt (10 μm defocused electron beam, proxy for bulk meteorite composition): SiO2=45.1±2.0, TiO2=0.54±0.38, Al2O3=24.3±6.2, Cr2O3=0.21±0.19, MgO=6.5±2.9, FeO=8.2±3.8, MnO=0.11±0.05, CaO=14.9±1.9, NiO=0.03±0.07, Na2O=0.49±0.13, K2O=0.10±0.03 (all wt%), n=40.
Classification: Lunar (polymict breccia)
Specimens: 24g including a probe mount on deposit at UNM.
Meteorite Designation: NWA 6963
History: (H. Chennaoui Aoudjehane, FSAC) In mid-May, 2012, the NWA 6963 locality, near the river Oued Touflit, became widely known and hundreds of meteorite hunters went to the area searching for more pieces. Pieces ranging from 100 to 700 g have been recovered, as well as a few small pieces (3-10 g), most of them are broken and partially covered by a thin fusion crust. The total mass may be as much as 8-10 kg.
Physical Characteristics: The original recovered material was a shiny, dark, 83 g fusion-crusted stone in three pieces. Minimal weathering. Interior shows abundant maskelynite and shock melt vein.
Petrography: (C. Agee, UNM) Microprobe examination of a polished epoxy mount shows 60% pyroxene, 35% maskelynite, 2% ulvöspinel, 2% melt pockets with silica, minor merrillite, trace chlorapatite and pyrrhotite. Pyroxenes show core-to-rim zonation. Pyroxene grains 200 μm to >1 mm, maskelynite domains 50 μm to >1 mm.
Geochemistry: (C. Agee and N. Wilson, UNM) Two distinct pyroxene compositional trends. Pigeonite Fs29Wo11En59 to Fs58Wo16En26, average: Fs39.7±7.7 Wo13.0±2.3 Fe/Mn=33±3 N=108. Augite Fs21Wo34En45 to Fs39Wo31En30, average: Fs28.1±6.2Wo31.6±1.9 Fe/Mn=31±3 N=24. Maskelynite Or2.3±0.7Ab48.3±2.1An49.4±2.6 N=9. Oxygen isotopes (Z. Sharp, UNM): δ18O=4.332; δ17O=2.528; Δ17O=+0.241 (all per mil).
Classification: Achondrite (Martian, shergottite); minimal weathering, high shock grade based on complete transformation of plagioclase to maskelynite. Pyroxene compositional trends are similar, but not identical to Shergotty.
