AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Cannot be reliably estimated from a photograph; the dark streaks appear natural figure or mineral staining rather than proof of age.
Common Uses
High-end furniture, cabinetry, decorative slabs, veneers, boxes, turning, guitars, ukuleles, and other instruments.
Geographic Origin
Hawaiian Islands, especially the larger islands and upland forests.
Workability
Works reasonably well, though curl can cause tear-out; use sharp cutters, light passes, and backers. Sands and finishes well; predrilling is advisable.
Finish Recommendations
Seal with dewaxed shellac if needed, then apply oil, lacquer, or wiping/polyurethane finish; use a clear finish to preserve figure and color.
Notable Features
Distinctive three-dimensional curl, warm golden color, and strong chatoyance; prized for visual and acoustic qualities.
