Most likely black walnut; the pale, irregular outer band may be sapwood or a contrasting graft/wood inclusion. Similar-looking walnut species are possible.

Grain Pattern
End-grain view shows distinct growth rings and diffuse, irregular dark zones; face-grain figure cannot be reliably judged from this cut section.
Color & Appearance
Dark gray-brown heartwood contrasts sharply with pale cream sapwood. The exposed surface looks weathered or oxidized; walnut heartwood often lightens with prolonged light exposure.
Hardness (Janka)
1,010 lbf — Medium
Durability & Decay Resistance
Moderately durable; heartwood has some decay resistance, while sapwood is less resistant to insects and rot.
Value & Age
Roughly US$8–20 per board foot for common kiln-dried stock; figured or premium-grade lumber can cost more.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Cannot be estimated reliably from a photograph; growth-ring count would indicate tree age, not the age of this cut sample.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, and decorative work.
Geographic Origin
Eastern and central North America, especially the eastern United States.
Workability
Generally machines and finishes well, though irregular grain may tear out; predrill for fasteners and use sharp tools.
Finish Recommendations
Sand evenly and apply oil, shellac, lacquer, or clear polyurethane; a clear finish preserves the contrast, while stain may obscure it.
Notable Features
Strong heartwood–sapwood contrast and conspicuous dark streaking are visible. Walnut is valued for its color and often has a mild, distinctive scent when freshly worked.
