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 slab’s age cannot be determined visually; its surface appears relatively fresh, with no reliable patina or wear evidence.
Common Uses
High-end furniture, live-edge slabs, cabinetry, veneer, turning, gunstocks, and decorative panels.
Geographic Origin
Claro walnut is native to California and Oregon; related walnut species grow across western and eastern North America.
Workability
Generally machines and sands well, though irregular grain can tear out and spalting may create brittle areas. Pre-drilling is advisable; standard glues and finishes perform well.
Finish Recommendations
Use sanding sealer followed by wiping oil, shellac, lacquer, or clear polyurethane; a clear finish best emphasizes the figure. Fill or stabilize open checks before coating.
Notable Features
Exceptional figure and chatoyance, contrasting dark streaks, and possible spalting; visible checks may require stabilization or resin filling.
