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 image cannot establish chronological age; the surface appears commercially finished or lightly weathered, with no reliable antique patina indicators.
Common Uses
High-end furniture, cabinetry, veneer, guitars and ukuleles, decorative boxes, turning, and specialty interior trim.
Geographic Origin
Native primarily to Hawaii, especially the major mountainous islands.
Workability
Generally machines and sands well, though curly grain can tear out during planing; use sharp cutters, light passes, and a high cutting angle. Gluing and finishing are usually straightforward.
Finish Recommendations
Apply a clear lacquer, shellac, or wiping varnish to emphasize chatoyance; sanding sealer and careful surface preparation help prevent uneven absorption.
Notable Features
Exceptional three-dimensional flame/chatoyance, decorative color variation, and strong instrument-making appeal; figure can vary substantially within one board.
