Hi! I have quite a few rocks that I’ve found. I believe are mostly quartz; what other minerals they contain is beyond my very low level of expertise! The smaller smoother round ones I chiseled out of a large slab of slate. The larger and much rougher ones I actually found under my deck. All of them were found in Chester County, Pennsylvania which is in the south eastern part of the state. Can you please help me identify them? Also, the third picture I provided is after I tumbled a few of them.
