Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain with a medium texture and moderate natural luster. The visible surface shows a flat-sawn cathedral pattern consistent with commercial furniture grade lumber.
Color Description
Heartwood is a rich, dark chocolate brown with a deep reddish-purple undertone. The finish highlights a medium luster. Over time, walnut naturally lightens and develops a warmer golden-brown patina.
Hardness Rating
1,010 lbf (Medium Hardness)
Durability Rating
Very Durable; highly resistant to decay and rot, though less resistant to insect attack than some other hardwoods.
Common Uses
High-end furniture, cabinetry, veneer, interior trim, flooring, and gunstocks.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$12.00 to $18.00 per board foot for Select/Better grade.
Wood Age Estimate
The piece appears to be a modern piece of furniture, likely 10-20 years old, based on the wear patterns in the finish and the consistent oxidation of the wood beneath the topcoat.
Sustainability Status
Not CITES listed and classified as 'Least Concern' by the IUCN. Readily available as FSC certified.
Workability
Excellent workability with both machine and hand tools. It glues, stains, and finishes extremely well, though it can occasionally exhibit tearout during planing if the grain is irregular.
Notable Features
Distinctive mild, spicy scent when worked. High tannin content can cause dark staining when in contact with iron and moisture.
Finish Recommendations
Oil-based polyurethane or lacquer is recommended to enhance the depth of the grain. A clear topcoat is best as stains can muddy the natural beauty of the wood.
Identification Confidence
Medium-High; the grain structure, pore distribution, and the specific reddish-chocolate hue under the finish are hallmarks of American Black Walnut used in furniture construction.
