This new meteorite display features a genuine piece of the Moon - a small sample of lunar meteorite NWA 4734.

The meteorite specimen is encased in a clear acrylic gemjar which is placed inside a handsome display box that has a black pebblegrain finish and a glass viewing window.  The Moon Rock can be removed from the case and handled or examined.  The color artwork inside the display has a retro-vintage astronomy theme and it was laser printed for highest quality.  This display would make the ideal gift for someone who has everything.  This would also make a fine outreach or educational prop and it would look great on display in the office or observatory.

I only have a limited supply of these displays. 

Refer to the photo.  The black centimeter cube is shown for scale and is not included.

From the Meteoritical Bulletin entry for NWA 4734 :

Northwest Africa 4734

Rissani, Morocco

Find: October 2006

Achondrite (lunar)

History: Two pieces were purchased from nomads in Erfoud, Morocco, in October 2006 and February 2007.

Physical characteristics: A. Habibi purchased two pieces with a total mass of 477 g in Rissani, Morocco; several other pieces of the same stone totaling 895 g are with Ait Elkaid in Rissani, Morocco. Dull black/brown fusion crust is nearly complete and inside slightly tarnished where absent. It is a gray, coarse-grained, pristine magmatic rock consisting of millimeter-sized phenocrysts of mainly pyroxene and plagioclase.

Petrography: (A. Jambon, O. Boudouma, and D. Badia, UPVI). The texture is best described as shergottite-like. Pyroxene grains are highly fractured while plagioclase laths, partly transformed to maskelynite, are only affected by a small number of fractures. Silica and silica-feldspar glass are minor components. A few patches of impact melt are also observed. Ilmenite, baddeleyite, zirconolite, tranquilityite, pyrrhotite, and metal. Fayalite associated with silica probably results from the dissociation of iron rich pyroxene. Modal mineralogy (vol%): Cpx 50, plagioclase + K-feldspar 32, silica + glass 7.5, opaques (ilmenite, Ti-magnetite, pyrrhotite) + fayalite 7, voids + fractures 3.

Geochemistry: Mineralogy by EMP and SEM. (Trace and major element analyses ICP-MS and ICP-AES, J.-A. Barrat, UBO). Pyroxene grains are complexly zoned (En₆₅Fs₂₁Wo₁₃ to En₂Fs₈₃Wo₁₅; FeO/MnO = 78 [average]). A few compositions correspond to pyroxferroite. Plagioclase is normally zoned from An_75-91 (average An₈₉) with minor olivine (Fa_80-95). Chondrite normalized REE pattern with an enrichment of 53 (La) to 40 (Yb). Trace element pattern with negative anomalies of Sr and Eu. Interstitial glass is high in silica (75 wt%) and contains microcrysts of K-feldspar with a significant celsian component. The chemistry and major and trace elements are identical to NWA 032-479-773 and LAP 02205-02224-02226-02436- 03632. The texture is very similar to that of the LAP specimens. The very low abundance of olivine and the relative abundance of silica in NWA 4734 are the main differences beside the grain size and the slightly different composition of the major phases.

Classification: Achondrite (lunar); extensive shock.

Type specimens: A total of 20 g of sample and one polished section is on deposit at UPVI. Mbarek Ait Elkaid holds the main masses.
