AllendeCV3 Carbonaceous Chondrite. It fell at 1:05 AM on February 8, 1969 over the town of Allende, Mexico. The meteorite exploded in the air in a brilliant fireball and scattered thousands of pieces over an area 30 miles long. The total known weight is over two tons. Allende is the largest stone fall for total weight known! When the main mass exploded, the individual fragments continued to burn and thus they exhibit a nice primary and secondary fusion crust. Most Allende stones have areas of missing fusion crust probably due to spalation. This is caused by the stones hitting each other while still falling. You can clearly see this in the photos below. The slices exhibit incredible chondrules some of which show the pyrite-like crystals under a good scope! This meteorite is absolutely crucial for any meteorite collection. It is the most studied meteorite in history. Allende is starting to get hard to get. Prices are rising on this meteorite.
