Macadamia spp. of the family Proteaceae. A couple of the species produce the familiar (and delicious) macadamia nuts and others produce a similar but poisonous nut (bummer!). I am not familiar with this wood so cannot vouch for any of these colors. I note that it appears to be strikingly similar to lacewood in grain and color and somewhat to American sycamore in grain (but not color).

planks listed as Hawaiian macadamia
planks listed as macadamia nut, so presumably these are from the non-poisonous nut variety

pen blanks listed as macadamia / Macadamia integrifolia

turning block dry, moistened, waxed
end grain dry and moistened
This set of pics of a turning block in various states was provided by cane maker Meilie Moy-Hodnett, whom I thank for this and other contributions to the site. As Meilie pointed out to me, this is a wood where moistening makes a significant difference in the appearance of the wood, and very much for the better.
