Thanks once again for your feedback. I will do the "scratch test" when I get home from work and let you know what happens. The rock is really interesting--unlike any other I found at the site. If you get time I would like to see the illustrations on my photos.
(Later) Did the scratch test and found that the white part did not scratch.
