One of the wood choices for pipes is Arbutus which is also commonly referred to as Strawberry Wood for its color. Not as popular of a pipe making material as Briar, it can offer some very interesting grain patterns which can be brought out through sandblasting. Arbutus is also less dense than briar, so it is lighter which is a big advantage in a big pipe.
This pipe from Morgan Pipes is from the Bones series which are pipes that come "unfinished" and will color naturally with smoking. This one in particular is a favorite of mine, as I really love the swirls which sort of remind me of "starry night" by VanGogh.
