Only 1959 g in the World- RUMURUTI Chondrite R3-6

Fantastic piece of rocky meteorite, of the rare Rumuruti-type chondrite found in the Sahara desert, analyzed and recently classified under the official name NWA 13683. It is an intact, very aesthetic specimen, without fractures, in which already on its outer surface we can appreciate dozens of chondrules in the form of small circles, each representing the tiny grains of matter that formed the presolar cloud, before the planets and the Solar System as we know it today. That is why chondrites like this contain the oldest materials we can find in the Solar System, with an estimated age of more than 4.550 billion years. For its part, the meteorites of type R owe their name to the first specimen of this type that was seen fall in the town of Rumuruti (Kenya) in 1934. They form a rare group of chondrites which, although they have many aspects in common with ordinary chondrites such as similar chondrules, few refractory inclusions or similar chemical composition, differ in that they present a higher proportion of fine-grained matrix, clasts of various lithologies from the parent body and contain little iron in the form of metallic particles; almost all the metal they contain is oxidized or in the form of sulfides. An excellent opportunity to add this wonder of the universe to your collection. Quality and size for a great collection.
