welcome to the site ,your rock looks like quartz to me .

I’ll second that. I bet that would look great cut flat and polished.

Yes it is quartz, the yellowing is due to iron impurities (or stains) in its composition.

Yes, it is quartz... but more specifically, it is a Metamorphic version of quartz called Quartzite. A major ID-clue for Quartzite is the "flakiness" visible on a broken Quartzite surface -- which we see especially in your 3rd and 6th photos. Compare them with the photos of Quartzite specimens here:
Quartzite: Metamorphic Rock - Pictures, Definition & More (geology.com)

Quartzite was originally a Sedimentary rock called sandstone, which in the millions of years after it was originally formed became so extremely deeply buried in the earth that the great pressure and heat at that depth caused the quartz sand-grains to recrystallize in a different form, i.e., Metamorphosis.
