I am new to this. Looks like a quartz cluster? Possibly hematite creating the color?

Yes, this is quartz. And the color is due to iron oxides, possibly hematite but could be an ambiguous mixture of iron oxide minerals. If you look carefully, I think you can see that the color zone is somewhat inside the current crystal surfaces - it formed on an earlier crystal surface and then was enclosed by further crystal growth.

If you're new to this, you have a good eye, and/or you bring some other prior experience to your identification. Well done!
