Identity HelpNeed help with two I.D.'s (one pink and the other bright red)

Need help with two I.D's

The first one is small pink crystals in a green schist-like matrix.

I thought it was Calcite, because I thought the cleavage looked like that, but the hardness is much higher. A steel knife does not scratch them at all.

It is much more pink-colored than the photos show.

(material found in Guatemala)

The second piece has bright red. There is a large section of it, as well as smaller veins and sections in other pieces. The other side has a thin coating of a creamy white-pink mineral. The white-pink mineral I'm not sure, but it scratches easily. The red one I had thought Hematite, but I've never seen it this bright before. Thoughts?

The red thing might be garnet and the pink iron stained quartz. The pink may also be feldspar. If feldspar you should be able to scratch it with a steel file , if quartz no. The last photo looks like a calcite crust, test it with acid.

Robert, I think Reiner has nailed it.
