Grain Pattern
Flat-sawn cathedral pattern with straight to slightly irregular grain; features classic parabolic arches and occasional wavy figure typical of temperate hardwoods.
Color Description
Medium to dark brown heartwood with some lighter tan/honey streaks; sapwood is pale yellowish-white. It typically develops a rich patina and lightens slightly with age and UV exposure.
Hardness Rating
1,010 lbf (Medium Hardness)
Durability Rating
Durable and very resistant to decay; however, sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, veneer, gunstocks, interior trim, flooring, and specialized wooden objects like bowls or handles.
Geographic Origin
Eastern United States and parts of Southern Canada.
Market Value & Sustainability
Estimated Market Value
Approximately $12.00 to $18.00 per board foot depending on width, grade, and local availability.
Wood Age Estimate
Freshly milled or surfaced based on the lack of oxidation, clean edges, and bright color consistency; likely harvested within the last 1-3 years.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable in North America.
Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes well. Can occasionally exhibit tearout if the grain is irregular near knots.
Notable Features
Distinctive mild, spicy scent when worked; contains juglone which can be an allergen to some users; moderate natural luster.
Finish Recommendations
Responds exceptionally well to penetrating oils (like Tung or Linseed oil) which enhance the grain; polyurethane or lacquer provide excellent protection and depth.
Identification Confidence
High; the distinct cathedral grain pattern, chocolate-brown heartwood hues contrasted with white sapwood, and the porous texture are diagnostic characteristics of Juglans nigra.
