DISCLAIMER: Do not have a proper kit to test moh's hardness so my comments on hardness should be taken with a grain of salt So The purple/yellow/red rock was found just outside of Yellowstone national park on the Yellowstone river flowing out of the park. It was one piece and was later cut into 8 different pieces. It has a hardness comparable to quarts. The green and brown gem was found about 15 miles outside of Billings, Montana while searching for agates. It was over 30 miles away from the Yellowstone river so it wasn't brought from anywhere far away most likely. It has a moh's hardness of at least 6. I have absolutely no information about the origin of the last sedimentary rock. I assume it was found in Montana or the neighboring states. It has a mohs hardness of at least 5 but has many fractures making it prone to breaking if hit or dropped too hard. village.photos/members/meatrocks/first-set-of-gems

The first brown "banded" one is opalized wood.
