Color can be highly variable, but tends to be medium golden or reddish brown, similar to Mahogany. There are usually contrasting bands of color in the growth rings, and it is not uncommon to see boards with ribbon-like streaks of color. Boards figured with wavy and/or curly grain are also not uncommon. With the tree endemic to Hawaii only, and with supplies dwindling, Koa is likely to be rather expensive. Also, boards of highly figured and/or curly Koa can command fantastic prices.
