Color Description
Heartwood varies from light grayish brown to dark chocolate brown. Sapwood is yellowish-gray to nearly white. The sample shows typical oxidation darkening to a deep brown over time.
Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable and very resistant to heartwood decay, though sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, gunstocks, interior trim, veneer, and small specialty wood objects.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot depending on figure and grade.
Wood Age Estimate
Modern cut (less than 10 years old) based on clean edges and moderate oxidation.
Sustainability Status
Not listed on CITES Appendices or the IUCN Red List; widely available and sustainable in its native range.
Workability
Generally easy to work with both hand and machine tools. It glues, stains, and finishes very well, though it has a medium blunting effect on cutters.
Notable Features
Distinctive mild, spicy odor when being worked. Known for its excellent dimensional stability and shock resistance.
Finish Recommendations
Penetrating oils or wiping varnishes effectively highlight the grain. Polyurethane is recommended for high-wear surfaces.
Identification Confidence
High; the color palette, grain sprawl, and specific dark streaking are classic indicators of Juglans nigra in a small turning blank format.
