    Unknown rock.

    I got this thing thing in the bahamas. It was at this little shack close to the beach that was also selling shells. Was hoping some of you rockhounds would be able to help.

    looks like a bit of quartz and mica, with a crust of basalt or something. But I'm definitely not good at IDing rocks.

    I agree about the quartz & mica - it looks like some kind of granitic rock, with a bit of what it intruded into. But that makes no sense if it originated in the Bahamas, which is a carbonate platform. Can you show us some other angles, maybe with better light?

    That's hard to tell. Looks like quartz. I can't tell if its mica or just camera reflection off the rock. However mica is pretty easy to ID in person. And its a common associate with quartz. Is the color accurate? It looks very pink.

    Lick it. Maybe its salt.

    Sorry bout the one pic, ill try to get a couple more today. It looks like most of it is some kind of brownish quartz, the top is like a pinkish/skin colored that isnt quarts and the bottom looks like it milted to form like a dark root beer solid color.

    That's a great suggestion PAK. A salty evaporite is much more plausible than an igneous rock out there. Even though it doesn't look like that to me.
