Grain Pattern

Logs show bark rather than enough exposed face grain to assess figure; cut ends appear pale, coarse, and irregularly cracked.

Color & Appearance

Freshly exposed wood is pale tan to yellow-brown, with darker bark. Black locust heartwood typically darkens from yellow-green to golden or brown with age.

Hardness (Janka)

1,700 lbf; Hard (near the Very Hard threshold).

Durability & Decay Resistance

Very Durable; black locust heartwood resists decay and insects, especially outdoors.

Value & Age

Estimated Market ValueNot an official valuation

Roughly $5–12 per board foot for usable black locust lumber; log value varies greatly by size and local market.

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 estimate the tree’s age from this image; logs appear freshly cut, with no clear weathering or patina.

Common Uses

Fence posts, decking, outdoor furniture, flooring, turning, and durable construction.

Geographic Origin

Black locust is native to the eastern United States and widely planted elsewhere in North America and Europe.

Workability

Hard and potentially abrasive to tools; predrilling is useful, and interlocked grain can cause tearout. It glues and finishes well when surfaces are prepared.

Finish Recommendations

For outdoor use, apply a penetrating exterior oil or suitable exterior coating; indoors, oil, varnish, or polyurethane work well.

Notable Features

Black locust is dense, strong, and exceptionally decay-resistant; the pictured bark is deeply furrowed.
