AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Relatively fresh cut or recently surfaced; the lack of deep oxidation and the crispness of the grain suggests it is not an antique reclaimed piece.
Common Uses
High-end furniture, musical instruments (especially ukuleles and guitars), boat building, cabinetry, turned objects, and decorative veneers.
Geographic Origin
Endemic to the Hawaiian Islands, USA.
Workability
Generally easy to work, thoughfigured boards frequently cause significant tearout during planing and jointing due to interlocked grain; glues and finishes well.
Finish Recommendations
High-gloss finishes such as lacquer or polyurethane best highlight the figure; Danish oil or shellac are excellent for a more natural feel that pops the grain.
Notable Features
Famous for its "3D" chatoyancy (shimmering effect); lacks a distinctive scent but is prized for its resonance in acoustic instruments.
