Juglans nigraHardwood

Black Walnut

Grain Pattern

Straight grain with a medium texture; displays a slight cathedral pattern typical of flat-sawn lumber

Color Description

Heartwood ranges from a deep chocolate brown to a lighter pale brown; sapwood is pale yellow-gray to nearly white. Typically darkens with age and develops a rich patina

Hardness Rating

1,010 lbf (Medium)

Durability Rating

Very Durable; highly resistant to heartwood decay, though susceptible to insect attack

Common Uses

High-end furniture, cabinetry, veneer, gunstocks, interior paneling, and wood turning

Geographic Origin

Eastern North America (United States and Canada)

Market Value & Sustainability

Estimated Market Value

$12.00 - $20.00 per board foot depending on grade and width

Wood Age Estimate

The visible patina and oxidation suggest the sample is likely 10-25 years old if finished

Sustainability Status

Not listed in CITES Appendices or on the IUCN Red List; widely available and generally managed sustainably

Workability

Excellent workability with both hand and machine tools; glues, stains, and finishes very well, though it can occasionally have irregular grain that causes tearout

Notable Features

Distinctive mild odor when being worked; known for its high shock resistance and dimensional stability

Finish Recommendations

Penetrating oils or wiping varnishes are recommended to highlight the natural grain and chatoyance; polyurethane for higher durability

Identification Confidence

Medium; the color profile and grain structure are highly characteristic of Juglans nigra, though low image resolution makes definitive pore analysis difficult
