AI-generated identification · may be incorrect- Type
- Hardwood; exotic/tropical
- Origin
- Native primarily to the Hawaiian Islands, especially on upland volcanic slopes.
- Hardness
- Janka approximately 1,170 lbf — Medium (near the hard threshold).
- Durability
- Moderately durable; heartwood has useful resistance to decay, while sapwood is less resistant. Outdoor weathering is not its strongest application.

Grain Pattern
Predominantly straight grain with pronounced tight curl/flame figure and mild irregularity; likely flat- or quarter-sawn veneer/board.

Hardness (Janka)
Janka approximately 1,170 lbf — Medium (near the hard threshold).
Durability & Decay Resistance
Moderately durable; heartwood has useful resistance to decay, while sapwood is less resistant. Outdoor weathering is not its strongest application.

Approximately $40–$120+ per board foot for attractive figured koa; exceptional highly figured stock can exceed this range.
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 polished photograph; the surface appears relatively modern, with no clear antique patina or wear.
Common Uses
Fine furniture, cabinetry, musical instruments, luxury veneer, small boxes, turning, and decorative panels.
Geographic Origin
Native primarily to the Hawaiian Islands, especially on upland volcanic slopes.
Workability
Generally machines and sands well, though curly grain can tear out; use sharp cutters, light passes, and a high-angle or scraping finish. Gluing and finishing are usually straightforward.
Finish Recommendations
Apply a wash coat or thin shellac if needed, then use clear lacquer, wiping varnish, or oil to maximize figure; avoid overly amber finishes that obscure contrast.
Notable Features
Exceptional three-dimensional chatoyance, warm color, and acoustic resonance; dark inclusions may represent small knots or mineral/stress marks.
