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.

Pallasovka           49°52′0′′N, 46°36′7′′E

Volgograd district, Russia

Find: July 1990

Pallasite

History: One stone weighing 198 kg was found by N. F. Kharitonov at a shore of an artificial water reservoir, 27.5 km from the town of Pallasovka. Interestingly, the town was named after Peter Pallas (1741–1811), a famous naturalist who took part in the discovery and the first study of the Pallas Iron Mass, which was found near Krasnojarsk in 1749 and gave the name of the pallasite meteorite group. A. E. Milanovsky transferred a sample of the meteorite to the Vernadsky Institute, Moscow.

Petrography and Geochemistry: (M. A. Ivanova, N. N. Kononkova, Vernad; S. E. Borisovsky, Institute of Geology of Ore Deposits, Mineralogy, Moscow)

Petrography: The stone consists of approximately equal parts of olivine and metal, and has abundant brown, rusty fusion crust with regmaglypts.

Geochemistry: Olivine (mg# 87.7, Fe/Mn = 45.2, Fe/Mg = 0.14; similar to main group pallasites). Metal (bulk ICP AES) Ni = 13.1 wt%; Ir = 0. 12, Au = 2.8, Pt = 3.2, Ga = 22.5, Ge = 24.9 (all ppm). Kamacite (Co = 0.61, Ni = 7.21; both wt%) and taenite (Co = 0.35, Ni = 26.5 both wt%). Additional phases: Troilite (Ni = 0.41 wt%), schreibersite, and chromite (mg# 36; Fe/Mn = 48.9; Cr/(Cr+Al) = 77.2). Note: Chromites in this sample differ in composition from that of the main and groups.

Classification: Pallasite (Main group).

Specimens: A 9336 g sample and one polished section are on deposit at Vernad. The main mass is held by an anonymous purchaser.
