Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain with medium-to-coarse texture; some swirling figure visible near the contoured edge where the grain transitions to end-grain.
Color Description
Heartwood is a rich, medium chocolate brown with darker streaks; sapwood (not prominently visible here) is typically pale yellowish-white. It develops a lustrous patina and lightens slightly to a warmer honey-brown over years of UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable and very resistant to heartwood decay; moderate resistance to insect attack, though sapwood is susceptible.
Common Uses
High-end furniture, cabinetry, gunstocks, interior paneling, veneer, turned items, and small luxury wooden crafts.
Geographic Origin
Eastern North America (United States and Canada)
Market Value & Sustainability
Estimated Market Value
$10.00 - $18.00 per board foot depending on width and figure quality.
Wood Age Estimate
The sample appears modern (1-5 years) but shows signs of recent hand-finishing or sanding, with a fresh matte-to-satin sheen.
Sustainability Status
Not listed in CITES Appendices or the IUCN Red List; widely available and generally considered sustainable with FSC certification common.
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes well, though it can occasionally produce tearout if grain is irregular.
Notable Features
Distinctive mild, spicy scent when worked; contains juglone which can be a mild irritant; known for its exceptional dimensional stability.
Finish Recommendations
Oil-based finishes (tung oil or linseed oil) enhance the deep color and grain; clear polyurethane or lacquer provide excellent protection while maintaining the natural chocolate hue.
Identification Confidence
High; the deep chocolate coloring, specific pore structure visible in the side grain, and the way the wood responds to the rounded profile are classic indicators of Juglans nigra.
