Koa & other Hawaiian Woods
Koa (in photo above) (Acacia koa)

Koa, the best known of Hawaiian woods, grows year round and can reach heights of 100 feet.  The specific gravity is around .55, making it similar to American Black walnut in density.  It has been used for centuries by Hawaiians to make wa'a (dugout canoes).   It is a great wood for many purposes including musical instruments, bowls and all kinds of projects where a medium weight wood can be used.   Our figured Koa has the beautiful chatoyance in the curl seen in the photo above, and the distance between curls vary (the one above has very tight, close curl).    All of our figured wood comes from the stumps of dead or dying trees, havested legally on private land.  As best we can tell, it is not classified as endangered.  The biggest threat to Koa in Hawaii appears to be overgrazing of cattle.   Click here  for a larger detail of the Koa photo.

Grading explanation for figured wood:
Gallery grade minus (gg-) is a nicely figured piece that has some figure scattered around, not tight or all over figure
Gallery grade (gg) is a highly figured piece of wood. It has very high and intense figure on at least two parallel sides, or very good figure on 3 or 4 sides.
Gallery grade PLUS (gg+) is a piece with rare intense figure that appears on all 4 surfaces of a square. Usually uncommon to rare.

New! Macadamia wood now added.  See on this page below the Koa.

Macadamia wood
(macadamia integrifolia)

Macadamia wood has an appearance much like lacewood/leopardwood, but has a pinkish cast and slightly different markings. The color can look like red stain with a finish.   Just like lacewood, the appearance of the markings changes based on the angle the wood has been cut.  The wood often develops multiple defects when drying, which makes it very important to buy truly dry wood.  These pieces have been kiln-dried completely.

The freshly cut wood looks like the lighter pieces.  If exposed to light without a finish, the
pieces gradually look like the darker ones above.  The darker color is only skin deep, and
as soon as the piece is sanded, the lighter color is apparent.  Sample photo of typical pieces.
