They are also separated by the groups the minerals are in, such as sulfides, etc.
Some of the pictures are right on to what the minerals that I see in the labs look like, but then some don't even look close to what my hand samples look like.

Only advice would be not to do as the kit advises by just taking a hammer to the rock. What I did to achieve clean breaks on about 19 of my geodes: examine the rock for where it might be likely to break open or where you would like it to break if you want to take a risk haha, it can pay off.

Forestry Suppliers. Thoreau in his boat at the foot of the path. After briefly describing my book project, I inquired whether they had rights to the drawing, which I had mistakenly identified as the work of Louisa May Alcott, rather than of her sister Abigail May Alcott. Mike agreed to have one of their interns look into it.
When I phoned back the following week, he said they no record of the photo, and suggested I try the Concord Free Public Library instead. Just before hanging up—and perhaps to mitigate my disappointment—he mentioned that somewhere in storage on the property was a rock and mineral collection by Henry Thoreau. He then described how it had been on exhibit for decades in the original farmhouse museum before being moved into long-term storage a few years back. I could barely contain my excitement.
