Market Value & Sustainability
Estimated Market Value
$10.00 to $18.00 per board foot depending on width, grade, and local availability.
Wood Age Estimate
The sample appears modern with a contemporary satin finish, likely milled within the last 5 to 10 years.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List of Threatened Species; generally considered sustainable and widely available.
Workability
Commonly easy to work with both hand and machine tools. It planes smoothly, glues well, and takes stains and finishes excellently. Can occasionally experience tear-out in figured areas.
Notable Features
Features a distinct, mild, spicy scent when being worked; known for excellent dimensional stability and shock resistance.
Finish Recommendations
Oil-based finishes (tung or linseed) enhance the natural depth, while clear polyurethane or lacquer provide durability. Avoid heavy stains to preserve the natural chocolate tones.
Identification Confidence
High; the characteristic chocolate-brown color paired with the semi-ring porous pore structure and grain pattern is highly indicative of North American Black Walnut.
