Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Highly irregular and figured, containing burl, crotch figure, and wavy grain patterns. It features a natural face-like abstract figure caused by branch inclusions and tension wood.
Color Description
Sharp contrast between cream-colored or yellowish-white sapwood and dark, chocolate-brown to purplish heartwood. It features medium luster and may lighten slightly over time with heavy UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable heartwood, resistant to decay and rot; sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, gunstocks, interior paneling, veneer, turning, and artistic woodworking projects such as live-edge slabs.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$10.00 - $25.00 per board foot for high-figure or burl slabs; standard lumber is usually $6.00-$10.00.
Wood Age Estimate
Recently harvested/processed (under 2 years) based on the fresh appearance of the bark and lack of significant oxidation on the sapwood surfaces.
Sustainability Status
Generally sustainable and widely available in North America; not listed in CITES Appendices or on the IUCN Red List.
Workability
Generally easy to work with hand and machine tools, though figured areas (like the burl shown) are prone to tearout and requires sharp blades and light passes.
Notable Features
Distinctive mild, spicy scent when worked. Contains juglone, which can be an allergen for some woodworkers. Known for excellent dimensional stability.
Finish Recommendations
Penetrating oils or wiping varnishes are highly recommended to enhance the figure and chatoyancy. Clear polyurethane or lacquer can be used for more durable protection.
Identification Confidence
High; the distinct stark white sapwood bordering a deep brown heartwood, coupled with the bark texture and characteristic Walnut figure, is diagnostic for Juglans nigra.
