Market Value & Sustainability
Estimated Market Value
$10.00 - $18.00 per board foot depending on region and FAS grade.
Wood Age Estimate
Relatively recent/kiln-dried stock; minimal oxidation or patina suggesting wood was surfaced within the last 1-3 years.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally managed sustainably.
Workability
Excellent. Easy to work with both hand and machine tools. Glues, stains, and finishes very well, though can produce fuzzy surfaces if tools are not sharp.
Notable Features
Distinctive mild, sweet walnut scent when worked. Fine texture and relatively lightweight for its strength.
Finish Recommendations
Drying oils (tung or linseed) or polyurethane to enhance the deep brown tones. Shellac is also an excellent sealer.
Identification Confidence
High. The coffee-brown color, distinct cathedral grain pattern, and visible pore structure are characteristic of Juglans nigra.
