Grain Pattern

Typically straight to slightly interlocked with a very fine, even texture; high natural luster. Large growth rings are generally absent or indiscernible.

Color & Appearance

Heartwood is usually jet-black with little to no visible grain. Sapwood is pale yellowish-white, clearly demarcated from heartwood. It maintains its deep black color over time but can gray if exposed to heavy UV without protection.

Hardness (Janka)

3,220 lbf (Extremely Hard)

Durability & Decay Resistance

Very Durable. Excellent resistance to termites and rot, though its primary value leads it to be used indoors where durability is less of a concern than stability.

Value & Age

Estimated Market ValueNot an official valuation

$100.00 to $150.00 per board foot (extremely expensive, often sold by weight)

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Modern harvest likely; it shows a clean jet-black finish typical of kiln-dried or stabilized commercial stock without traditional patina or oxidation.

Common Uses

Piano keys, fingerboards for stringed instruments (violins, guitars), billiard cues, carvings, turned objects, and high-end cabinetry inlays.

Geographic Origin

West and Central Africa (primarily Cameroon, Gabon, and Equatorial Guinea)

Workability

Difficult to work due to extreme density and hardness. Has a high dulling effect on cutters. Hard to glue due to high natural oil content. Polishes to a very high natural luster.

Finish Recommendations

Usually left natural or finished with clear wax or oil to highlight the deep black color. Does not require heavy film finishes because it polishes so well on its own.

Notable Features

Extremely heavy (sinks in water); one of the most expensive woods in the world. Dust can be a potent skin and respiratory irritant for some users.
