My name is Ruben Garcia - aka MrMeteorite - and I’m a meteorite hunter, dealer, and collector. I began my meteorite adventures in 1998 and since then I have found many thousands of meteorites as well purchased and sold many thousands more.

I’ve been featured in many books and magazines about meteorites. Publications like Sky and Telescope, Discover, Iguana, Meteorite Times, and even the latest book by O. Richard and Dorothy Norton, called “What’s so Mysterious about Meteorites?”

I’ve also been featured in such TV shows as, Cash and Treasures, Meteorite Men, Nova Science NOW with Neil deGrasse Tyson, and the United Stats of America - a program all about various statistics - with Sklar Brothers as hosts. Of course, I’ve also been the subject of newspaper articles all across the country as well as various NPR and BBC radio shows.


You can bid with confidence since everything I sell is guaranteed to be exactly as listed. I include a handwritten (business card size) certificate of authenticity with each specimen. If you have a question, please feel free to send a message before bidding.

Hassi Messaoud 001        31°51.11’N, 6°58.59’E

Ouargla, Algeria

Find: 2020 Mar 11

Classification: Martian meteorite (Nakhlite)

History: Found on March 11, 2020, near the town of El Borma. Later acquired in 2021 by Matthew Stream from Aziz Zad.

Physical characteristics: Specimen is grayish-brown and displays a slightly weathered, minor fusion crust.

Petrography: (D. Sheikh, FSU) Specimen displays a cumulate texture (~1.1 mm grainsize) consisting primarily of compositionally zoned, prismatic or blocky (sometimes twinned) augite (displaying Fs-rich rims), ferroan olivine, and plagioclase; modal abundances: 75% augite, 15% plagioclase, 5% olivine. Accessory phases (modal abundance: 5%) are primarily found either in the mesostasis or within melt inclusions in augite or olivine grains; these phases include ferropigeonite, low-ca pyroxene, titanomagnetite, Si-Al-Na-Fe-K-rich glass, and fluorapatite.

Geochemistry: Olivine (Fa73.3±1.0, range Fa72.6-74.5, Fe/Mn = 50±1, n=3), Augite (Fs30.1±4.7Wo38.4±1.4, range Fs22.8-37.9Wo34.9-40.3, Fe/Mn = 32±4, n=47), Pigeonite (Fs58.6±4.9 Wo9.9±3.8, range Fs53.3-62.9 Wo6.6-14.0, Fe/Mn = 31±2, n=5), Low-Ca Pyroxene (Fs64.5±4.1Wo3.1±0.9, range Fs61.1-70.2Wo3.0-5.3, Fe/Mn = 35±2, n=8), Plagioclase (An37.2±1.3Or2.9±0.5, range An35.3-39.4Or2.0-4.0, n=27).

Classification: Martian (nakhlite). Sample is a martian meteorite due to the Fe/Mn ratios of olivine and pyroxene, and due to the plagioclase composition. Sample is a nakhlite due to the high modal abundance of augite and cumulate texture observed.
