Likely black walnut (the dark strip); the broad pale center may be walnut sapwood. The sample also appears adjacent to a separate, darker finished floor surface, so identification is provisional.

Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, and musical instruments.
Geographic Origin
Eastern North America, especially the central and eastern United States.
Workability
Generally machines, sands, glues, and finishes well; figured areas can tear out during planing. Pre-drilling is useful near edges.
Finish Recommendations
Sand evenly and use oil, shellac, lacquer, or clear polyurethane; a clear finish preserves the color contrast.
Notable Features
Attractive heartwood–sapwood contrast; walnut is relatively stable and develops a rich brown tone. No scent or acoustic traits can be established from the image.
