Do I need a metal lath for something so small?

I'm building a fire pit. I had some extra border stones and started building the core out of them. I plan to clad the exterior, top, and interior in stones.

I'll be using a refractory mortar for the interior details, and type s for the exterior.

(I've conducted refractory tests on a representative sample of the stones. This was done in environmental conditions that far exceed any natural conditions from wood fires/nature. These stones will not explode and will not spall.)
