Value & Sustainability
- Estimated Market Value
- $18.00 to $28.00 per board foot for lumber; higher for premium veneer sheets.
- Wood Age Estimate
- Modern sample (under 20 years old) in good, processed condition used as marquetry or veneer.
- Sustainability Status
- Listed as Endangered on the IUCN Red List due to habitat loss and overexploitation. Subject to strictly regulated international trade.
Common Uses
High-end furniture, architectural millwork, fine flooring, musical instruments (especially guitar fingerboards), decorative veneer, inlay work, and turning.
Geographic Origin
Central Africa (Democratic Republic of the Congo, Republic of the Congo, Cameroon, Gabon, Equatorial Guinea)
Workability
Challenging due to high density, splintering tendencies, and dulling effect on cutting tools. Splinters can cause localized infection. Glues reasonably well; finishes well after grain filling.
Finish Recommendations
Pore filler is recommended if a smooth sheen is desired. Responds exceptionally well to penetrating oil finishes (danish oil, tung oil) or polyurethane and clear lacquer.
Notable Features
Extremely distinct dark-and-light banding pattern (parenchyma bands), natural oils, high resistance to abrasion, sand dust can cause severe allergic reactions (respiratory/skin irritation).
