Juglans nigra • Hardwood
Grain Pattern
Straight to semi-irregular with a moderate cathedral figure and fine, open pores; shows classic flat-sawn texture
Color Description
Medium chocolate brown heartwood with darker streaks; sapwood is typically creamy white (not visible in this cut). Over time, it tends to lighten towards a golden brown upon UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable; heartwood is highly resistant to decay but susceptible to insect attack (especially powder post beetles).
Common Uses
High-end furniture, cabinetry, veneer, interior paneling, gunstocks, turned objects, and novelty items.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
Approximately $12.00 - $18.00 per board foot depending on grade and width.
Wood Age Estimate
Relatively recent/modern milling based on the clean surface finish and lack of deep oxidation or heavy patina.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable.
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes very well, though can occasionally suffer from grain tearout during planing if grain is irregular.
Notable Features
Distinctive mild, spicy scent when worked; contains juglone, which can be an irritant; prized for its rich color and dimensional stability.
Finish Recommendations
Oil-based finishes (tung oil or linseed oil) enhance the deep color; clear polyurethane or lacquer provide excellent protection while maintaining appearance.
Identification Confidence
High; the characteristic chocolate-brown hue, open pore structure, and specific cathedral grain development are hallmark traits of Juglans nigra.
