Market Value & Sustainability
Estimated Market Value
$10.00 - $18.00 per board foot depending on figure and width.
Wood Age Estimate

Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally sustainable.
Workability
Excellent workability with both hand and machine tools. Glues, stains, and finishes very well. Can occasionally have surfacing tearout if grain is irregular.
Notable Features
Distinctive mild, spicy odor when being worked. Known for its shock resistance and dimensional stability once seasoned.
Finish Recommendations
Oil-based finishes (tung oil, Danish oil) or polyurethane to enhance depth of grain and provide protection for handles.
Identification Confidence
High; the deep chocolate brown color, distinct growth ring patterns, and semi-porous texture are classic indicators of Juglans nigra.
