Eastern North America
Market Value & Sustainability
Estimated Market Value
$10.00 - $18.00 per board foot depending on figure and width.
Wood Age Estimate
Modern carving; the patina and texture suggest the item was produced within the last 5-15 years based on the lack of deep oxidation or wear on the ridges.
Sustainability Status
Abundant; not CITES listed or on the IUCN Red List; widely available with FSC certification.
Workability
Excellent workability with both hand and machine tools. Planes and glues well; holds stains and finishes exceptionally well, though the dust can be an irritant.
Notable Features
Distinctive mild spicy scent when worked. Contains juglone, which can be an allergen for some. Known for its dimensional stability and shock resistance.
Finish Recommendations
Oil-based finishes (tung oil or linseed oil) or polyurethane to enhance the deep brown color. Wax is excellent for carved textures to provide a soft luster.
Identification Confidence
High; the characteristic chocolate-brown color, distinct pore structure visible in the carved grooves, and common use in North American woodcarving strongly indicate Black Walnut.
