Only that stripy American black stuff.
I had a lovely deal last year. Bought a couple of thick boards of "American" walnut and paid accordingly. Except that it was actually _Armenian_, which runs to at least 5x the price.
English walnut is nice (most of my stock is locally felled), but it's still not a patch on the Caucasian stuff.
