Polished Gilded Blackstone (Nether Block)

Polished Gilded Blackstone is just regular gilded Blackstone but with all of the gold on the sides of the block. I would imagine that you can only get this fancy looking block by placing Gilded Blackstone in a 4 by 4 space in a crafting table then you would get the beautiful looking block. Here is what the block might look like.
