Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain with a medium-coarse texture; the sample shows a flat-sawn cathedral-like pattern with some slight irregular figure and visible open pores characteristic of Juglans species.
Color Description
Heartwood is a rich, medium to dark chocolate brown. Sapwood (visible at the edge) is typically creamy white. This sample displays characteristic dark streaks and a matte luster that will develop a lustrous patina and lighten slightly to a golden brown over time with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Very Durable; highly resistant to heartwood decay, though sapwood is susceptible to insect attack. Excellent dimensional stability.
Common Uses
High-end furniture, cabinetry, gunstocks, interior paneling, veneer, turned objects, and musical instruments.
Geographic Origin
Eastern North America (United States and Canada)
Market Value & Sustainability
Estimated Market Value
$10.00 - $18.00 per board foot depending on grade and width.
Wood Age Estimate
The sample appears to be modern rough-sawn lumber, likely aged 1-5 years post-harvest based on the crispness of the rough-cut marks and the lack of deep oxidation or graying.
Sustainability Status
Commonly available and stable; not listed on CITES Appendices or the IUCN Red List of Threatened Species. Widely available with FSC certification.
Workability
Generally easy to work with both hand and machine tools. It planes well, glues, and finishes effectively. Occasionally sensitive to tear-out on pieces with irregular grain patterns.
Notable Features
Distinctive mild, spicy scent when worked. Known for its excellent strength-to-weight ratio and ability to hold fine detail in carving and turning.
Finish Recommendations
Best finished with oils (linseed or tung) to enhance the natural depth of color, or clear lacquer/polyurethane for protection. Does not require staining as its natural color is highly prized.
Identification Confidence
High; the combination of chocolate-brown coloration, pore structure visible on the rough surface, and the distinct contrast with the dark edge staining are classic indicators of North American Black Walnut.
