How To Tell If Its A Meteorite

[Nuggetmaster]

So this has been a yard orndimat  for many years and I'm sick of not really knowing what it is. How can one find out what something is and what's its value. Its none magnetic and very heavy for its size.

I'm a bit skeptical of it being a meteorite, but it is hard to tell from photos.  Iron meteorites have a rusty coating and of course respond to a magnet with a loud clank!  Stoney meteorites are usually coated with a black crust.  Inside they are often granular, a bit like granite, or composed of dark green olivine.  It's an odd shape for a meteorite lacking aerodynamic qualities.  Looks a bit like a petrified pregnant rock troll.  :  )
