There are some exotics out there that are gorgeous for sure. Snakewood is one, but it's hard to find big pieces.
I have a back and side set of "mysterywood" that looks kind of like lacewood. It came from South America and I can't figure out what species it is. I really need to take pics. Maybe someone here knows.
I had a lacewood ukulele from Kala Ukes that we gave away in a prize drawing for Ukulele Player Magazine. The lacewood was from the Far East. The uke had a solid spruce top, too. It made for a good acoustic combination. The lacewood, in this case, was a dappled grain. In a piece like that, it is hard to see the heartwood, there was so much dappling.
Here's a picture...
