Allende is one of the most famous of all witnessed falls and no collection is complete with an example of it. Until the fall of Allende, carbonaceous CV-type meteorites were extremely rare and were present only in large museums or the in the cabinets of wealthy collectors. But all of that changed on February 8, 1969 when a few thousand fragile black stones rained down on the Mexican countryside around Pueblito de Allende in Chihuahua province Mexico. During this single fall, more CV3 meteorites fell to Earth than all of the previous ones in history put together. Suddenly, this super rare carbonaceous type meteorite was available to average collectors. Allende is a Vigarano-type carbonaceous chondrite - it is also a witnessed fall and a hammer fall. This meteorite has a characteristic black matrix with light colored chondrules and white CAI's. (Calcium Aluminum Inclusions - the oldest matter in the solar system).
