Tungsten Brick

The sparkle carries over from the ore, so a placed wall of this catches the light in a way plain stone brick never does. That effect is the only reason to pick it. Early on your Tungsten Bars belong in a pickaxe and a set of armor, so most builders come back to this material later, once the ore has stopped deciding anything.

Up close the pattern is Mythril Brick with every small brick cut in half. From a few tiles away the two read as the same material, so you can mix them in a large build and stretch whichever one you happen to have more of.
