ok, this might sound a little strange and silly, but i was just wondering if anyone could tell what minerals does this rock contain? It is quite complex and of different "hardness" (if that's the word) on every side. Thanks.
The translucent stuff looks like quartz; try scratching it with a steel knife or nail - it should be pretty tough to scratch. The silvery stuff is mica (probably a biotite mica), which should peel off in very thin layers. The pinky mineral is orthoclase feldspar. Looks like a lump of granite to me

Hey! Unfortunately, all the links you provided give 404 errors. Try again?

by saying pinky, you mean orange? and there are like two more minerals in there. On the second picture - one very white and another one not so much.

Looks pink on my monitor, but I think we're talking about the same one

I think the white one is plagioclase feldspar (sorry, I missed that one). The not-so-white one will be quartz.
