American Black Walnut (with heavy curly figure)
Juglans nigra • Hardwood
Grain Pattern
Heavy curly figure, often called fiddleback, with wavy and interlocked grain visible. The pattern shows consistent ripples perpendicular to the grain direction.
Color Description
Dark chocolate brown heartwood with golden-yellow undertones. It exhibits high chatoyance in the curly figure and generally lightens/goldens over time with UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable to very durable regarding decay resistance, though moderately susceptible to insect attack.
Common Uses
High-end furniture, musical instruments (especially guitar backs and sides), cabinetry, gunstocks, and premium veneers.
Geographic Origin
Eastern United States and Ontario, Canada.
Market Value & Sustainability
Estimated Market Value
$15.00 - $35.00 per board foot for high-figure selection; standard walnut is significantly lower ($8-$12).
Wood Age Estimate
Modern sample with a fresh film finish; visible oxidation suggests the wood itself may be 5-10 years post-harvest.
Sustainability Status
Not listed on CITES or IUCN Red List; widely available as FSC certified, though high-figure trees are becoming more scarce.
Workability
Generally easy to work with hand and machine tools, though figured areas are prone to grain tearout during planing. Glues and stains very well.
Notable Features
Distinctive faint, spicy scent when worked. Known for its excellent dimensional stability and shock resistance. Fine, uniform texture.
Finish Recommendations
Oil-based finishes (tung or linseed) or clear lacquers are best to enhance the depth of the curly figure and natural chatoyance.
Identification Confidence
Medium-High; the pore structure and deep brown-gold hue are classic for Juglans nigra, and the intense 'fiddleback' ripple is a prized mutation specific to fine hardwoods of this type.
