Stonecut Gilded Blackstone

You should be able to put gilded Blackstone into different shapes like other kinds of stone. For example, you should be able to put it into slabs, stairs, polished version, etc. Also, you should be able to craft Glided Blackstone (I know that's already been said but I thought it worth repeating). You could craft it with Blackstone in the middle of the table with a gold nugget in each corner.
