Andesite, Diorite, and Granite Bricks are uncraftable, and all the pillars are uncraftable, paved gabbro bricks are uncraftable, mossy and overgrown gabbro bricks are uncraftable, and gabbro tiles are uncraftable.

I think it's ok to keep it to the stone cutter - I actually really like this block. But JEI support for it is something which should be added to JEI itself.

All craftable in the Stonecutter iirc. I wish there was a Stonecutter JEI plugin. That said it'd be nice to have them craftable in the crafting table like vanilla
