I Almost Threw This Rock Away. Then I Cut It Open

I almost left these in the creek bed. They looked like nothing — just gray, lumpy limestone, but... No sparkle. No crystal pocket winking back at me. Just ordinary rocks. Then I cut one open on a $60 Harbor Freight tile saw.What came out of this anciant marine deposit changed how I look at "ordinary" rocks forever. These nodules formed 300 million years ago on an ancient seafloor — and what they trapped inside is interesting and cool! 🪚 Harbor Freight 7" wet tile saw — budget lapidary setup 📍 North Texas creek — Cretaceous Washita Group 🔬 Calcareous nodules — marine concretions This is the Low Budget Lab in its purest form. No $3,000 slab saw. Just curiosity, a cheap tile saw, and rocks that most people would walk right past. What’s the best thing you've ever found inside an ordinary-looking rock?
