Market Value & Sustainability
Estimated Market Value
$10.00 - $18.00 per board foot depending on figure and width.
Wood Age Estimate
Freshly cut to moderate age (undetermined years); shows oxidation and rough-cut surface typical of raw lumber stock in a workshop environment.
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. Planes and glues well. Can occasionally have surfacing tearout if grain is irregular.
Notable Features
Distinctive mild, sweet, and nutty scent when worked. Contains juglone, which can be an irritant to some users and is toxic to some plants.
Finish Recommendations
Best with penetrating oils, shellac, or clear lacquer to enhance the natural dark tones. Heavy stains are rarely used as the natural color is highly prized.
Identification Confidence
High; the characteristic chocolate-brown color, ring-porous structure visible on the end grain, and coarse texture are classic indicators of Juglans nigra.
