Would someone please help me identify this rock that I've been polishing for over a year

Dunno but it's very pretty! Good job on that polish

My thought is a verity of Gneiss. It has a lovely look to it and makes me think of Van Gogh's Sarry Night.

Looks sort of like porphyry but I see layers so it’s probably a metamorphic rock of some sort.
