I've looked online for info to identify them but can't seem to find anything, so your help is greatly appreciated.
The first rock is generally smooth, multicolored (creamy orange-brown, brown, & white) with a slight (very slight) sheen. The 2nd one is flat yet layered and has a mirrored effect to it. It's blackish/grayish, very shiny/mirrored. The 3rd one is black/greyish and rough in texture. It is shiny in some spots and has a slightly mirrored effect. Here's a link to a ms paint illustration I attempted to do of them. Any help would be greatly appreciated. Thanks!
