Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot depending on figure and width
Wood Age Estimate
Freshly cut or recently milled (less than 1 year); shows minimal oxidation and clear, bright sapwood contrast.
Sustainability Status
Wide availability; not CITES listed or on the IUCN Red List of Threatened Species. FSC-certified options are common.
Workability
Excellent workability with both hand and machine tools. Planes and glues well. Can occasionally exhibit tearout in areas of irregular grain like those shown near knots.
Notable Features
Distinctive mild, spicy odor when worked. Contains juglone, which can be an allergen for some. Known for its exceptional dimensional stability.
Finish Recommendations
Penetrating oils or shellac to enhance the heartwood depth; clear polyurethane for durability. Darker stains are rarely used as the natural color is highly prized.
Identification Confidence
High; the distinct transition between the pale sapwood and coffee-colored heartwood, combined with the specific bark texture and knot structure, is characteristic of Juglans nigra.
