Need help with these two rocks please!

A few days we had a load of gravel brought in for our driveway. The rock is from Davis,Ok. Any time we get rock from there we find lots of crystals.
My ShihTzu and I were walking down our drive way and the rock on the right side of the pic grabbed my attention! The sun was making it shine the most radiant colors, like but better than any glitter. I picked it up and noticed it was more than a shiny rock! The next morning we walked and looked for more, I found the smaller piece on the right in the pics.
The larger rock is about 2"×4" and the smaller is beside a quarter 😁
