Market Value & Sustainability
Estimated Market Value
$12.00 to $20.00 per board foot depending on width, length, and figure.
Wood Age Estimate
Modern/Contemporary. The surface finish and lack of deep oxidation or historic tool marks suggest the wood was processed within the last 5-15 years.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable with FSC certification often available.
Workability
Generally easy to work with both hand and machine tools. It planes smoothly, glues well, and takes finishes extremely well, though it can occasionally have irregular grain that causes tearout.
Notable Features
Features a distinct, mild, spicy scent when being worked. Known for its excellent dimensional stability and shock resistance.
Finish Recommendations
Oil-based finishes (tung oil or linseed oil) or clear polyurethane are highly recommended to enhance the deep brown tones and natural luster.
Identification Confidence
High. The characteristic chocolate-brown color, pore structure, and grain movement are consistent with North American Black Walnut.
