Are eBay meteorites real?
It looks like an iron meteorite. Slice it or grind a part of it flat and etch the flat surface with strong acid, such as sulfuric or nitric acid. Widmanstätten patterns or Neumann lines may appear! Widmanstätten patterns are among my favorite of all phenomena. For what it’s worth, the surface looks characteristic of meteorites I’ve seen, with those shallow depressions. I am delighted to learn from popcassady’s link that these depressions are called ‘regmaglypts’.
