Color Description
Heartwood ranges from light to dark chocolate brown. Sapwood is typically pale yellow-gray to nearly white. This sample shows a rich, warm brown typical of heartwood that has likely been steamed or aged, showing a moderate natural luster. It will develop a lighter, more golden-brown patina over time with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating

Common Uses
High-end furniture, cabinetry, gunstocks, interior paneling, veneer, turned objects, and musical instruments.
Geographic Origin
Eastern United States and parts of Eastern Canada.
Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot depending on grade and width.
Wood Age Estimate
Modern sample; likely cut and milled within the last 10-20 years based on the crisp edges and moderate oxidation levels.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable in its native range.
Workability
Excellent workability with both hand and machine tools. It planes smoothly, glues well, and takes finishes exceptionally. It has a mild, pleasant odor when being worked. Large pores may require filling for a glass-smooth finish.
Notable Features
Distinctive chocolate scent when cut; contains juglone which can be a mild allergen for some. Known for its exceptional dimensional stability after seasoning and high shock resistance.
Finish Recommendations
Responds best to clear oils (Linseed or Tung) or polyurethane to enhance the natural dark tones. Shellac or lacquer are also common for a traditional look. Avoid heavy stains as they mask the natural beauty.
Identification Confidence
High. The chocolate brown color combined with the specific pore structure, medium texture, and the way the light hits the grain is highly characteristic of North American Black Walnut.
