Doug, let me give you some advice, take the photos in
dylight, the light you are using is horrible! Natural
sunlight takes true photos. That would be a start. I
think what you have could be an old mill ball. They
are common things to find here in the southwest. If it
is a meteorite, the fastest way is to cut and etch. It
would not damage the piece.
Otherwise, we will yap all year long and be no closer
to the truth.
