When trying to put Gilded Blackstone into a floor or ceiling made of raw Blackstone, it doesn't really fit in, because it has the same texture on all six sides. It'd be cool to have a top and bottom texture for it, even if the gold is in the same places as the side texture. It's nothing huge, it'd just be kind of cool to see
