.25" Aguas Zarcas Carbonaceous Chondrite (0.13 g) Fragment
This is a neat specimen: a .25" wide (0.13 gram) fragment of the incredibly rare Aguas Zarcas meteorite, a witnessed fall over Costa Rica on April 23, 2019. Fragments of this meteorite crashed into a doghouse! It shattered into hundreds of smaller fusion-crusted stones upon entry, mostly into angular pieces, though some oriented pieces have also been found. Six days after it fell, the area got rain: because so much was collected before and after the rain, scientists now have clear examples of what rain can do to fusion crusts on fresh meteorites. About 27 kilograms in total have been recovered.
Aguas Zarcas is classified as a CM chondrite, a rare kind of chondrite with fine-grained chondrules and matrices, as well as abundant hydrated minerals. It is highly brecciated, indicating a highly impacted parent body shaped by constant pummeling and accretion of asteroidal material. Its composition is similar to the famous Murchison meteorite from Australia. Aguas Zarcas even contains organic compounds, including sugar alcohols, caarboxylic acids, and other hydrocarbons!
This meteorite is highly prized for both its rarity and scientific value: take home this astronomical find today!

About CM2 Carbonaceous Chondrites
Carbonaceous chondrites are a rare and scientifically significant type of stony meteorite, representing only about 4% of all meteorites found on Earth. These meteorites are considered to be some of the oldest materials in the solar system, dating back over 4.5 billion years. They are composed primarily of silicate minerals but are unique for their high levels of carbon, organic compounds, and water-bearing minerals, offering a glimpse into the conditions of the early solar system.
Theys are divided into several groups, including CI, CM, CR, CO, CV, and CK, each representing different compositions and histories. CI and CM chondrites are the most primitive and are often rich in organic compounds. CI chondrites, like the Orgueil meteorite, are extremely rare and contain the highest known concentrations of organic materials among meteorites.
A CM2 chondrite is a type of carbonaceous chondrite meteorite with a high abundance of carbon and water-bearing minerals. The “CM” classification stands for the "Mighei-type," named after a meteorite that fell in Mighei, Ukraine. The "2" in CM2 indicates a specific petrologic (textural) type, meaning it has experienced low levels of alteration from water or heat compared to other chondrites, preserving more primitive materials.
