Hardness Rating
1010 lbf (Medium)
Durability Rating
Very Durable concerning decay resistance, though susceptible to insect attack. It is highly resistant to rot and weathering.
Common Uses
High-end furniture, cabinetry, gunstocks, interior paneling, veneer, flooring, and small wood objects/novelties.

Eastern United States and Eastern Canada
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot for Select/Better grade (unprocessed chunks vary).
Wood Age Estimate
Estimated 50-80 years. The deep oxidation and darkened appearance of the rough-cut face suggests this is heartwood from a mature tree, likely harvested several years ago.
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
Excellent to work with both hand and machine tools. It planes and glues well and holds a finish exceptionally. Can produce a faint, spicy scent when worked.
Notable Features
Features a distinctive mild scent when cut. Contains juglone, which can be an allergen for some horses if used as bedding, but generally safe for woodworkers. Highly sought after for its unique color and stability.
Finish Recommendations
Responds excellently to oils (tung or linseed), lacquer, and shellac. A clear finish is usually best to highlight the natural chocolate tones without staining.
Identification Confidence
High. The characteristic chocolate-brown color, coarse texture, and the way the fibers break along the growth rings are classic indicators of Juglans nigra heartwood.
