Market Value & Sustainability
Estimated Market Value
$12.00 to $18.00 per board foot regularly, depending on thickness and width grade.
Wood Age Estimate
Relatively modern/recent based on the lack of deep oxidation and clean surfacing; likely less than 5 years old as a processed sample.
Sustainability Status
Not listed in the CITES Appendices or on the IUCN Red List; widely available and generally managed sustainably throughout its range.
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes very well. Minimal tearout occurs even with irregular grain.
Notable Features
Distinctive mild, sweet, and nutty scent when worked; contains juglone which can be a mild irritant; world-renowned for its dimensional stability and shock resistance.
Finish Recommendations
Penetrating oils or wiping varnishes (like Danish oil or Arm-R-Seal) are recommended to highlight the natural chatoyance; clear lacquer also works well for a modern look.
Identification Confidence
High; the characteristic cool-toned chocolate brown color and large open pores visible in the face grain are hallmark features of Juglans nigra.
