Black Walnut (Figured)
Juglans nigra • Hardwood
Grain Pattern
Highly figured, featuring strong curly or 'tiger' figure perpendicular to the grain; the base grain is generally straight to slightly irregular.
Color Description
Heartwood is typically medium to dark brown with some lighter streaks, though the curly figure creates a high degree of chatoyance (light-refracting depth). Sapwood is creamy white to pale yellow. It tends to lighten or turn more golden-brown with age and UV exposure.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Very Durable; highly resistant to heartwood decay, though sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, musical instruments (especially guitar backs and sides), knife handles, turning, and decorative veneers.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$15.00 - $35.00 per board foot (standard walnut is $8-12, but high-figure material carries a significant premium).
Wood Age Estimate
Modern stock; the lack of deep oxidation or gray patination suggests it was recently milled or surfaced within the last 1-2 years.
Sustainability Status
Generally sustainable and not listed in CITES or on the IUCN Red List of threatened species; FSC certified stock is widely available.
Workability
Excellent workability with hand and machine tools, though the curly figure may cause tearout during planing if blades are not extremely sharp or if the angle is not adjusted. Glues, stains, and finishes exceptionally well.
Notable Features
Distinctive mild, spicy scent when worked. Known for excellent dimensional stability and shock resistance. Considered a 'noble' wood of North America.
Finish Recommendations
Oil-based finishes (like Tung oil or Linseed oil) or shellac are recommended to 'pop' the figure and enhance depth. Polyurethane provides more protection but can sometimes look plastic-like on high-figure wood.
Identification Confidence
High; the combination of the dark brown coloration and the rhythmic, compressed curly figure is highly characteristic of premium Black Walnut stock found in a luthier or cabinet shop setting.
