- Hardwood; possibly a live-edge or reclaimed offcut.
- Origin
- Eastern and central North America, especially the United States and southern Canada.

Grain Pattern
Predominantly straight to irregular grain, with severe localized distortion from knots, bark inclusion, and probable fungal spalting; cut orientation is unclear.
Color & Appearance
Dark chocolate-brown heartwood with pale gray-brown sapwood and irregular black-brown zones. Walnut generally lightens or mellows toward warm brown with age; the pictured surface is weathered and unfinished.
Hardness (Janka)
About 1,010 lbf Janka — Medium.
Durability & Decay Resistance
Moderately durable; heartwood has useful decay resistance, while sapwood is more vulnerable to insects and rot.
Value & Age
Roughly $8–25 per board foot for ordinary walnut; highly figured, sound slabs may cost substantially more. This damaged piece has low commercial value.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- The wood’s biological age cannot be determined from the image; surface weathering suggests months to years of exposure, not necessarily old timber.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, carving, and decorative live-edge work.
Geographic Origin
Eastern and central North America, especially the United States and southern Canada.
Workability
Normally machines and sands well, but knots, bark, checks, and spalting may cause tear-out and loosened material; sharp tools and careful clamping are needed.
Finish Recommendations
Stabilize loose areas with suitable clear resin, then sand carefully and seal with lacquer, shellac, or polyurethane; wipe-on oil can deepen contrast but may highlight uneven absorption.
Notable Features
Strong color contrast, attractive irregular figure, visible bark pockets, and possible spalting; defects significantly reduce structural usefulness.
