I think there is some opal in these: There is a bunch that is more brown-ish like this, but some is more blue and colorful. I just test-slabbed this little bit so far.

Hi, Quite sure it has some agate in it, given the fact that it's from the same area as the Turretella. I tried polishing some slabs of the same stromatolite as you have with mixed results (some areas polished well and others didn't). If you work them, keep us up to date on how things work out. Thanks, jeff
