Grain Pattern

Straight to slightly interlocked with a very fine, uniform texture. Pores are small and usually filled with dark mineral deposits, making them nearly invisible to the naked eye.

Color & Appearance

Jet black to dark brown heartwood, occasionally with grey or dark brown streaks. The sapwood is typically a pale yellow but is not present on this fingerboard. It has a high natural luster and develops a deep, silky patina with use.

Hardness (Janka)

3,220 lbf (Extremely Hard)

Durability & Decay Resistance

Very Durable. Highly resistant to rot, insects, and moisture; specifically chosen for fingerboards due to its resistance to wear from metal strings and perspiration.

Value & Age

Estimated Market ValueNot an official valuation

$100.00 - $150.00 per board foot (depending on the degree of jet-black color and absence of streaks).

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

Wood Age Estimate
The instrument appears modern and well-maintained. The wood itself is likely from a mature tree (200+ years) but was processed and installed within the last 5-15 years based on the string condition and finish luster.

Common Uses

Musical instrument fingerboards, piano keys, pool cues, high-end knife handles, turned objects, and inlay work.

Geographic Origin

Western Africa (primarily Cameroon, Gabon, and Congo).

Workability

Difficult. Its extreme density and high oil content cause rapid dulling of tool edges. It is prone to checking and splitting during drying, but it sands well and takes a high-natural polish without the need for extensive finish.

Finish Recommendations

Often left natural or finished with light applications of mineral oil or lemon oil to prevent cracking. Does not require lacquer or polyurethane due to its high density.

Notable Features

Extremely heavy (it sinks in water). Known for its high compressive strength and clear acoustic resonance. Some users report skin irritation or respiratory sensitivity to the fine dust.
