While hunting for invertebrates in the Peace River, you occasionally come across tan colored chert nodules that look sort of like molten wax or taffy. I ignored these for years until I decided to cut and polish one and was surprised with the colors inside. I've started tumbling the ones I've been getting lately and thought I'd show the transformation. Here are the nodules I picked up yesterday: This next batch was collected last week and are wet after a week tumbling with 80 grit. I think they look very cool and what an excellent additional incentive look for fossils. I'll rough tumble a few more batches and then run all of them together through to polish.

Hello, I have a rather large rock in my yard (middle Tennessee) which I have always thought was interesting. I’m hoping somebody will let me know which type(s) of rock it is? It has gray and white crystals(?) of some sort on top, along with white streaks running through it. It also has several knobby areas. Are these chert nodules? Any information is appreciated. Thanks!
