NWA 18131 is a 220-gram ordinary chondrite of the L6 type.
It was discovered in July 2025 in Morocco in the Chwichiya concentration zone by Elguirah El Houssine near the site where NWA 7831, a diogenite achondrite, was found.
A magnificent collector’s item, this unclassified chondrite was discovered in the Sahara, most likely in Morocco.
What makes this piece unique is its weight, but also the regmaglypts on its surface.
Regmaglypts are hollow indentations, often thumb-shaped, found on certain meteorites.
Entering the atmosphere slows down the trajectory of meteorites due to air friction.
This friction tears off pieces, forming regmaglypts.
The Tatahouine meteorite is a very beautiful achondrite diogenite meteorite, which fell on June 27, 1931 at 01:30 am, 4 kilometers northeast of the village of Foum Tataouine in Tunisia. The explosion woke up the whole population and also the French garrison. The next day French legionnaires found some fragments.
The diogenite meteorites come from the asteroid Vesta.
The Sikhote-Alin meteorite is an iron meteorite that fell in Siberia in 1947. This fall is unique in the history of meteorites, given the 70 tonnes that survived the journey through the Earth’s atmospher
It is often considered as the “Rosetta Stone” of planetologists, because it has improved our knowledge on the origins of our solar system. This meteorite was formed before our planet, in the very first moments of the solar system. It preserves in its heart the traces of the nebula which generated the Sun and its procession of planets.
Ivory tectites are the rarest tectites in the world.
I guarantee the authenticity of these ivories, they were purchased directly from the discoverer, Jean-Christophe Flabeau.
Jean-Christophe Flabeau acquired 120 of these tektites at a flea market. They were collected on a cotton plantation in Daoukro in western Ivory Coast between 1955 and 1970.
The parent crater, 10 km in diameter, is located in Ghana.

Jdiriya 004 is a rare and fresh rumuruti R3 chondrite weighing only 142 grams.
Magnetic susceptibility, chondrule diameters, mineral chemistry and texture suggest that it is an R3-4 breccia.
Only 10 meteorites of this type are classified to date.
The R chondrite group does not clearly belong to any of the major chondrite classes (ordinary, carbonaceous, enstatite); R chondrites have sub-solar Mg/Si and refractory/Si ratios, oxygen isotopic compositions that are above the terrestrial fractionation line and ordinary chondrites, and strongly oxidized mineralogy.
The first R chondrite, Carlisle Lakes, was found in Australia in 1977.
