Value & Sustainability

Estimated Market Value
$100.00 - $150.00 per board foot (usually sold by weight due to density).
Wood Age Estimate
Modern sample likely processed within the last 5-10 years; shows minimal oxidation or centuries-old patina.
Sustainability Status
CITES Appendix II listed; IUCN Red List status: Endangered. Trade is strictly regulated.

Common Uses

Tool handles, bearings, bushings, pulley wheels, mallet heads, and heavy-duty marine applications (ship propeller shaft bearings).

Geographic Origin

Central America and Northern South America (Caribbean islands specifically).

Workability

Extremely difficult to work; high density and natural oils dull cutters quickly and make gluing difficult. Turning and polishing are the preferred methods.

Finish Recommendations

Usually left unfinished or simply buffed/waxed; natural oils can cause lacquer or polyurethane to peel.

Notable Features

Produces a mild, perfume-like scent; high natural oil content makes it self-lubricating; it is dense enough to sink in water.
