Grain Pattern
Straight to irregular grain with a flat-sawn cathedral pattern visible in the center; medium texture and natural luster with occasional wavy figure near junctions.

Heartwood is a rich, dark chocolate brown (unsteamed appearance); sapwood is a distinct creamy white to pale tan visible on the right edge. It tends to lighten to a golden-brown over time with exposure to UV light.
Hardness Rating
1,010 lbf (Medium)

High-end furniture, cabinetry, veneer, gunstocks, interior trim, flooring, and small wood objects.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$10.00 to $18.00 per board foot depending on width, grade, and local availability.
Wood Age Estimate
Modern lumber, likely kiln-dried and recently surfaced. No significant oxidation or historical patina present.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable with FSC certification often available.
Workability
Excellent workability with both hand and machine tools. Glues, stains, and finishes well, though it can occasionally exhibit tearout when planing pieces with irregular grain.
Notable Features
Distinctive mild, spicy scent when being worked; contains juglone which can cause sensitized reactions in some woodworkers; highly prized for its unique cool-toned brown color.
Finish Recommendations
Tung oil or Linseed oil to enhance natural color; clear polyurethane or lacquer for protection. Does not require staining as its natural color is its primary appeal.
Identification Confidence
High; the combination of chocolate-colored heartwood, creamy sapwood line, semi-porous grain structure, and cathedral figure is diagnostic of Juglans nigra.
