Plain-Language Guide

Macassar Ebony is the striped ebony — completely distinct from solid-black Gaboon Ebony. The alternating black and golden-brown heartwood stripes are bold and unmistakable. Extremely dense and heavy (sinks in water), very hard on tools, and commands premium prices. Supply is genuinely limited due to restricted range and slow growth. The dust is a serious sensitizer. For small decorative objects, knife handles, and inlay work, there's nothing quite like it visually.

Common Mistakes
  • Confusing it with Gaboon Ebony — Macassar has bold striped figure; Gaboon is solid black
  • Trying to glue it without surface prep — the natural oils prevent good adhesion
  • Expecting quick work — at this density and hardness, go slow and use sharp carbide
Color & Appearance

Sapwood

Bold alternating black and rich golden-brown to reddish-brown stripes throughout the heartwood. The striped pattern is consistent and dramatic. Sapwood is yellowish-white and sharply distinct.

One of the most challenging woods to work. Extremely dense and heavy. Sharp carbide tools essential — dull quickly. Very fine texture takes an exceptional high-gloss polish when finished carefully. Gluing requires thorough surface prep.

Sustainability: Not currently CITES listed, but endemic to Sulawesi with limited range. Under commercial pressure. Buy from reputable suppliers who can trace origin. Population trends are concerning.
