Market Value & Sustainability
Estimated Market Value
$10.00 to $18.00 per board foot depending on width, grade, and local availability.
Wood Age Estimate
Modern sample (5-15 years); showing contemporary finish and typical kiln-dried coloration without deep atmospheric patina.
Sustainability Status
Common and widely available; not CITES listed or on the IUCN Red List of threatened species. FSC-certified options are common.
Workability
Excellent workability with both hand and machine tools. It planes, turns, and sands well, though some tearout can occur on figured areas. Glues and finishes exceptionally well.
Notable Features
Distinctive mild, sweet scent when being worked. Known for its dark color and excellent dimensional stability once seasoned. Dark spots (pith flecks or bird pecks) are common identifying features.
Finish Recommendations
Oil-based finishes (Danish oil, Tung oil) enhance the depth and richness of color. Polyurethane or lacquer are recommended for high-wear surfaces. Shellac is an excellent sealer.
Identification Confidence
High; the specific chocolate brown color, pore structure, and characteristic "pitting" marks are diagnostic indicators of Juglans nigra.
