Identifying a meteorite through a short description is very
difficult. There are so many different kinds of meteorites that it is
best to have it physically examined to determine its authenticity.
Having said that though, I would recommend getting doing some
research online and seeing what you can find or checking with any
college you may have nearby with a geology department.
Most people are familiar with the nickel-iron meteorites which are
naturally very heavy and usually covered in a layer of oxidation, but
there are other types such as stoney meteorites which are contain
very little metal (if any at all). Often, these will have a layer of
black crust on them called “fusion-crust” where the meteorite was
scorched entering our atmosphere. There are also more exotic
meteorites such as pallasites which contain crystals of olivine
(otherwise known as peridot) inside of a nickel-iron matrix. To see
an truly exceptional example, look up the Esquel meteorite. It is
very beautiful to see!
I realize this certainly doesn’t answer your question, but hopefully
it will give you a starting point. Also, I would highly recommend the
book, “Rocks from Space: Meteorites and Meteorite Hunters” by O.
