Grain Pattern

Usually straight or slightly interlocked grain with a very fine, even texture and high natural luster.

Color & Appearance

Heartwood is usually jet-black, with little to no discernible grain. Occasionally features dark brown or gray streaks. Sapwood is pale yellow and clearly demarcated.

Hardness (Janka)

3,080 lbf (Extremely Hard)

Durability & Decay Resistance

Very Durable; heartwood is highly resistant to termite attack and rot, though sapwood is susceptible to powder-post beetles.

Value & Sustainability

Estimated Market Value
$75.00 - $120.00 per board foot; often sold by weight or small turning blanks due to high cost.
Wood Age Estimate
Sample appears to be a modern offcut, likely harvested within the last 5-10 years based on clean mechanical cuts and lack of oxidation on the sapwood.
Sustainability Status
Listed on CITES Appendix II and classified as Endangered on the IUCN Red List due to over-exploitation.

Common Uses

Piano keys, musical instrument parts (fingerboards, pegs), pool cues, carvings, knife handles, and fine inlay.

Geographic Origin

Equatorial West Africa (Cameroon, Gabon, Equatorial Guinea, Congo, Nigeria).

Workability

Difficult to work due to extreme density; has a significant dulling effect on cutters. Hard to glue due to high natural oils. Takes a very high polish.

Finish Recommendations

Best finished with wax or light oils. Does not require heavy film finishes because it polishes to a naturally high gloss.

Notable Features

Extremely heavy (sinks in water), metallic clink when struck, faint medicinal odor when worked, and high oil content.
