Great specimen and great photo. What are the crystals covering the matrix?

| I believe that the matrix is covered with albite along with some quartz crystals.

I am afraid that there is no way this amethyst is from Grandfather Mountain, N.Carolina. There are no known amethyst localities on the mountain or, for that matter, anywhere even close to the mountain. In the museum at the nature center on the mountain there is a group of quartz crystals undoubtedly from Arkansas that is labelled as being from Grandfather Mountain. In my opinion, and I know the area very well, this is not possible. In fact, I am very certain that this specimen is not even from N. Carolina, it does not resemble other amethysts from the state.
I would further like to see the description of this piece changed from "quartz and amethyst." Amethyst is quartz, as we all know.
