I don't known what to call it beyond quarter sawed. I needed 6/4 for this top to match the rock but the best I had was this heavy cut 5/4. The wood wound up about 1/32 shy of the rock thickness but it will be ok.
I was concerned that this tree had ginormous growth rings which typically leads to homely wood. But in fact it turned out ok.
