I have been around the universe of starbound for awhile now. I pretty much know and have seen some beautiful variations of cobblestone that I personally would have wanted to use. but unfortunately when I harvest a cobblestone, I get cobblestone A and cobblestone A only, and boy is cobblestone A ugly. use it for roofing material and you will see the difference between other blocks. the artist has worked very hard on the look and the feel of the game, please make the other cobblestone harvest-able. It wont hurt, and it will give me more to build.
