Market Value & Sustainability
Estimated Market Value
Approximately $12.00 to $18.00 per board foot depending on thickness and width grade.
Wood Age Estimate
Relatively fresh cut (1-5 years) based on the crispness of the light sapwood and lack of deep oxidation or ambering.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally sustainable in its native range.
Workability
Excellent workability with both hand and machine tools. Planes and sands easily, takes glue and nails well, and finishes to a high luster.
Notable Features
Features a distinct, pleasant, mild spicy odor when being worked. Known for its exceptional dimensional stability after seasoning.
Finish Recommendations
Best suited for penetrating oils (tung or linseed) or clear polyurethane to enhance the natural dark tones. Avoid heavy staining.
Identification Confidence
High. The coffee-brown color palette, specific pore distribution, and the clear distinction between the creamy sapwood and dark heartwood are definitive for Juglans nigra.
