Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Highly figured crotch and book-matched grain with cathedral patterns, swirls, and significant chatoyance. The image shows a classic 'V' shaped crotch figure common where limbs meet the trunk.
Color Description
Rich dark chocolate brown heartwood with some lighter tan streaks. It typically lightens over time with UV exposure, moving toward a golden honey-brown. Low to medium natural luster.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable to Very Durable regarding decay resistance; susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, veneer, gunstocks, interior paneling, and musical instruments.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
Approximately $12.00 to $25.00 per board foot for high-figure selection.
Wood Age Estimate
Modern or mid-century (likely 20-50 years based on the oxidation state and finish wear), though the grain pattern is from an old-growth or mature tree.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List of Threatened Species; widely available with FSC certification.
Workability
Generally easy to work with hand and machine tools. It planes and glues well, though figured areas like the crotch seen here can experience grain tearout if not worked with sharp tools at a low angle.
Notable Features
Distinctive mild spicy scent when worked. Known for its exceptional dimensional stability and unique dark pigment that is prized globally.
Finish Recommendations
Oil-based finishes (tung oil or linseed oil) or polyurethane to enhance depth and figure. A grain filler can be used for a glass-smooth surface.
Identification Confidence
High; the combination of dark heartwood color, semi-ring-porous texture, and the specific 'feather' figure of the crotch grain is highly characteristic of North American Black Walnut.
