Gem? Need help with ID

[Darrow]

This stone was caked in dirt...not sure of it's origin. I bought a bag full of goodies and this was in it. I thought at first it might be ruby, but after washing it - it's purple like amethyst. It's heavy for it's size. Looks like a purple colored micah schist - hard, not flakey. Crystals have formed around it and then on it's surface - both sides. I see a couple of small reddish gemmy looking smoother crystals in one area. Do you see the triangle shape on the host? I am a novice and appreciate you taking time to help.

Amethyst quartz with mica or pyrite(I think)...

Sapphire? It does have an odd look, but the surface marks tell me its possible.

It looks like a corundum crystal. I would bet my whole rock collection on it.....(JK!) I can see the triangular striation on the top of it, and it looks like it also has the hexigonal shape over all, altho slightly rounded. I'll try and dig up a pic of one I have with the same triangular striation....

I think it is corundum. Thanks y'all!

Agree with Darrow. Corundum.
