Gonçalo alves

Gonçalo alves is the name given to several species of Astronium, a tropical hardwood. It is sometimes referred to as tigerwood—a name that underscores the wood's often dramatic, contrasting color scheme, that some compare to rosewood.

Appearance

While the sapwood is very light in color, the heartwood is a sombre brown, with dark streaks that give it a unique look. The wood's color deepens with exposure and age and even the plainer-looking wood has a natural luster.

Species

Two species are usually listed as sources for gonçalo alves: Astronium fraxinifolium^[1] and Astronium graveolens, although other species in the genus, including Astronium lecointei, may yield similar wood; the amount of striping that is present may vary. All trees grow in neotropical forests; Brazil is a major exporter of these woods, and is the origin of its Portuguese (language) name.
