High-end furniture, cabinetry, gunstocks, interior paneling, veneer, turned objects, and musical instruments.

Geographic Origin

Eastern United States and Southern Ontario, Canada.

Market Value & Sustainability

Estimated Market Value

$10.00 to $20.00 per board foot depending on figure and width.

Wood Age Estimate

Freshly cut to moderately seasoned; the presence of visible saw marks and rough texture suggests primary processing stage.

Sustainability Status

Not listed in CITES Appendices or on the IUCN Red List; widely available and generally sustainable in North America.

Workability

Excellent workability with hand and machine tools. Responds well to steaming for bending. Can suffer from tearout if grain is highly figured.

Notable Features

Distinctive, mild nutty odor when being worked. Known for its excellent dimensional stability and shock resistance. Fine, uniform texture.

Finish Recommendations

Responds exceptionally well to clear oils (Linseed, Tung) and polyurethane to enhance the deep color. Takes stains and waxes beautifully.

Identification Confidence

High. The characteristic chocolate-brown color, diffuse-porous structure, and prominent figure under rough-sawn conditions are diagnostic for Juglans nigra.
