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 board appears freshly machined with crisp edges and little oxidation; age of the tree or lumber cannot be determined visually.

Common Uses

Furniture, cabinetry, architectural millwork, flooring, gunstocks, veneer, turning, and instrument components.

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachian regions.

Workability

Generally machines, sands, glues, and finishes well, though reversing grain can cause localized tear-out; predrilling is advisable.

Finish Recommendations

Apply a penetrating oil or dewaxed shellac washcoat, followed by lacquer or polyurethane; sanding to 180–220 grit helps reveal the figure.

Notable Features

Moderate natural luster, attractive color variation, and characteristic dark mineral streaking; no strong scent is evident from the image.
