Likely black walnut; the pronounced swirling may reflect a knotty or figured slab. Claro walnut is a possible alternative.

Grain Pattern
Strongly figured, wavy and irregular grain flowing around knots; likely live-edge slab, with no clear evidence of quarter-sawing.
Color & Appearance
Warm medium-to-dark brown heartwood with lighter golden-brown streaks; walnut can darken and become more uniform with age and light exposure. Surface appears freshly finished, limiting color assessment.
Hardness (Janka)
1,010 lbf — Medium
Durability & Decay Resistance
Moderately durable; heartwood has some decay resistance, while sapwood is more susceptible to insects and rot; not especially weather-resistant.
Value & Age
Roughly US$15–40 per board foot for quality walnut; figured, wide slabs can cost substantially more, depending on region and drying.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Not reliably estimable from the photograph; the finished surface shows no clear patina or wear that dates the slab.
Common Uses
Furniture, tabletops, cabinetry, flooring, veneer, gunstocks, turning, and decorative slabs.
Geographic Origin
Black walnut is native to eastern and central North America and is widely grown in the eastern United States.
Workability
Generally machines and finishes well; figured grain can tear out during planing. Pre-drill near edges and use sharp cutters for clean results.
Finish Recommendations
Apply a clear oil, shellac, lacquer, or polyurethane; test first, as finish deepens the brown and emphasizes figure. Seal end grain to reduce uneven absorption.
Notable Features
Attractive swirling figure around knots; walnut typically has a mild, earthy scent and good stability when properly dried.
