Found in a walking trail in the mountains of montana. Only rock that looked like it. Picked it up dropped it to break and this was in the middle. And has greyish blu crystals that readily fall out. Any help identifying would be appreciated. Thanks a ton.
It is pegmatite, what we call around here "graphic granite". That is a heavy indicator that there are quartz crystals, probably smokey quartz and possibly even amethyst in the area you found that! The pinkish crystal form in the middle of the bottom pic is a poorly formed feldspar crystal. The bluish gray rock will be either quartz (probably smokey) or it could be moonstone, also a feldspar.
