The Renfrow meteorite was discovered as a single large mass on an unplowed hillside on a farm in Oklahoma in 1986. The original owner gave the unusual stone away as payment for a debt. Many years later in 1995, it was recognized as a meteorite and a sample was analyzed and classified as a L6 chondrite. Unusually, this meteorite contains grains of shocked maskelynite - a glassy, high-pressure mineral that is often found in Martian meteorites. Renfrow has a characteristic black matrix that shows a lot of fresh metal fleck and occasional shock veins.
The specimen being offered here is a professionally prepared slice. It is very thick and polished on one side. It weighs 25.3 grams.
