Tambo Quemado was discovered in 1949 in a remote part of the Andes. Brought to Lima in 1950, it was recovered by indigenous natives who traded the unique metallic stone for cement to build a school. Like Cape York (see lot 26), Tambo Quemado was classified as a IIIAB iron meteorite. Tambo’s unique crystalline structure, however, was determined to be the result of terrestrial reheating — most likely an attempt by natives to melt the meteorite for its iron. A meteorite’s etch can become less robust when terrestrially reheated, but not in this instance; this superlative partial slice features a dramatic etch on both sides. Prominently visible is an armored troilite inclusion as well as a small circular concavity featuring the meteorite’s external surface — clearly the bottom of a socket-like hollow in the mass. This is a choice partial slice of a meteorite with a matchless etch pattern. Modern cutting.
