Help with verification

[rippinrock]

I need to find out how to get a professional verification of this shell.  There are a set of 9 photos.  The first 7 were taken by a friend who is able to get better close ups than our camera does.  However, with his flash the true color of the shell doesn't show.  We took the last 2 pictures with our camera and these 2 pictures have the actual color of the shell.  There are spots on the pictures taken by our friend that are from his lens.  These spots are not actually on the shell.  You can see the spots also in the rest of the background.  His camera also produced shiny flash spots on the shell from the flash.
