Approximately 1,010 lbf Janka—Medium hardness.

Durability & Decay Resistance

Moderately durable; heartwood has reasonable decay resistance, while untreated sapwood is more vulnerable to insects and rot.

Value & Age

Estimated Market ValueNot an official valuation

About $8–$18 per board foot for ordinary surfaced black walnut; premium figure or wide boards can cost substantially 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 reliably dated from this image; the smooth, uniform finish suggests a manufactured or refinished surface rather than demonstrable age.

Common Uses

Furniture, cabinetry, flooring, paneling, gunstocks, turned work, veneer, and decorative millwork.

Geographic Origin

Eastern and central North America, especially the United States and southern Canada.

Workability

Generally machines, sands, glues, and finishes well; sharp tooling is recommended, and tear-out may occur with figured grain.

Finish Recommendations

Strip or lightly abrade to assess the wood; use a washcoat or conditioner for even staining, then apply wiping varnish, lacquer, shellac, or polyurethane.

Notable Features

Usually warm chocolate-brown, moderately heavy, stable, and capable of attractive chatoyance; the visible surface may be heavily stained.
