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

Geographic Origin

Eastern United States and parts of Southern Canada.

Market Value & Sustainability

Estimated Market Value

$10.00 - $15.00 per board foot depending on figure and width.

Wood Age Estimate

Freshly cut or recently milled lumber; shows minimal oxidation and sharp, machine-cut edges characteristic of contemporary stock.

Sustainability Status

Not listed in CITES Appendices or on the IUCN Red List; widely available and generally managed sustainably.

Workability

Generally easy to work with both hand and machine tools; glues, stains, and finishes very well, though some grain tearout can occur during planing.

Notable Features

Features a distinct, mild spicy scent when being worked; contains juglone which can be a mild irritant to some. High shock resistance.

Finish Recommendations

Responds excellently to oil-based finishes (tung or linseed) which deepen the color, or clear polyurethane for durability. Wax provides a beautiful satin luster.

Identification Confidence

High; the sharp contrast between heartwood and sapwood combined with the specific pore structure and chocolate-brown hue is diagnostic for Juglans nigra.
