Meteorites are classified into various categories.
Stony meteorites that are basically rocks are comprised of silicate minerals, iron meteorites have large amounts of iron and nickel, and stony-iron meteorites contain both metallic and rocky material. Many treasure hunters have made money by finding rare types of meteorites and selling them to museums or private collectors.
When a meteor falls to the ground, it leaves behind a hypervelocity impact crater, sometimes resulting in massive destruction.

This historic IID octahedrite iron piece was preserved in a castle in Bohemia, Czechoslovakia and dates back to ~1400 AD. During its fabled history, attempts were made to melt the mass in a primitive blast furnace. It also survived a 34-year stint at the bottom of a well between 1742 and 1776. Interestingly, the first use of the term Widmanstatten figure in a scientific publication was by Schreiber that published a print of the Elbogen iron made by Alois Beck von Widmanstatten himself. This specimen weighs 8.9 grams and was expertly prepared by R. Kempton of the NEMS.
