Makassar Ebony

Say "ebony" and people think black. And ebony is black, but Makassar is something more. Diospyros celebica, native to the island of Sulawesi in Indonesia, is the only ebony that carries a pattern with it: golden-brown and cream streaks against an almost-black background, alternating with a graphic precision no human hand could replicate. Where African ebony is uniform, austere, absolute in its blackness, Makassar is theatrical, every piece has its own combination of streaks, every cut reveals something different. The name comes from Makassar, the main port of Sulawesi from which this wood was shipped to Europe for centuries.
It's a wood that doesn't go easy on you. With a Janka rating of 3,220 lbf it's among the hardest woods used in craftsmanship altogether, dense enough to sink in water, capable of dulling tools in just a few passes, demanding and unforgiving toward anyone who doesn't respect it. But in skilled hands it yields surfaces that polish to a mirror shine with no extra finish needed, perfect edges, details that stay crisp for decades. In instrument making it's used for fretboards, bridges, and binding on top-tier acoustic guitars and basses, where its extreme hardness guarantees a wear resistance no other wood can match, and the streaks make every instrument visually one of a kind. It's classified as a vulnerable species by the IUCN due to excessive logging.
For laser engraving, the dark color is the main limitation: against such a deep background, engravings read poorly, and fine lines all but disappear. But this is a wood that doesn't need engraving to speak for itself, its beauty is already all in the material.
