Market Value & Sustainability
Estimated Market Value
$10.00 - $18.00 per board foot for kiln-dried FAS grade lumber.
Wood Age Estimate
Approximately 20-40 years for the finished piece/sample, showing a developed amber patina on the finish and typical surface oxidation of the wood fibers.
Sustainability Status
Least Concern (IUCN); widespread in its native range, not CITES listed, and broadly available with FSC certification.
Workability
Excellent; works very well with both hand and machine tools. Planes and sands to a smooth finish, holds screws and nails well, and glues reliably.
Notable Features
Features a distinct, pleasant, spicy scent when being worked; known for its stability once dried and its high resistance to shock.
Finish Recommendations
Responds exceptionally well to oil-based finishes (tung or linseed), wiping varnishes, and shellac which enhance its natural depth and color.
Identification Confidence
High. The distinct chocolate-brown coloration combined with the specific grain structure, pore distribution, and chatoyance is characteristic of Juglans nigra.
