While re-organizing and cleaning my art studio the other day, I came across a bag of agates that I assembled from sorting various rock collections that I have purchased the past few years. So for today's blog posting, I could not resist the urge to pull out my USB microscope camera to document some of the awesome detail. All of these agates are rough, non polished.
The first is a Lake Superior agate (three photos). Notice the reflective waxy luster, yellow limonite coating, some red color, and the botryoidal grape-agate formation.
Nice banding is exhibited in these Lake Superior agates....
The next photo shows intricate banding in a Botswana agate....
Another Lake Superior agate...
The next four photos, two each of two Lake Superior agates, show tube formations.

The last photo is a Brazilian agate.
