Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Highly figured cathedral grain with wavy and burl-like variations; book-matched veneer application creates a symmetrical 'butterfly' pattern across the center seam.
Color Description
Rich dark chocolate brown heartwood with warm undertones; moderate luster and subtle chatoyance in the figured areas; tends to lighten slightly over time with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable; very resistant to heartwood decay, though susceptible to insect attack (sapwood areas).
Common Uses
High-end furniture, cabinetry, boat interiors, decorative veneers, musical instruments, and small specialty wood items.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot for high-figure stock; veneer value varies by grade.
Wood Age Estimate
The furniture style and hardware suggest a piece from the mid-20th century (20-50 years old), with well-developed patina and characteristic oxidation.
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 exceptionally well, though figured grain requires sharp tools to prevent tearout.
Notable Features
Distinctive faint, spicy scent when worked; contains juglone which can be an allergen; prized for its strength-to-weight ratio and dimensional stability.
Finish Recommendations
A penetrating oil or satin lacquer is recommended to enhance the depth of the figure without looking plastic; shellac or polyurethane also work well.
Identification Confidence
High; the characteristic chocolate color, pore structure visible in the veneer, and the specific 'cathedral' figure are diagnostic of Juglans nigra.
