Value & Age

Estimated Market ValueNot an official valuation

Approximately $15–$35 per board foot for typical kiln-dried stock; premium old-growth or figured material may cost more.

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 this close-up; the surface appears relatively clean and recently finished, without definitive age indicators.

Common Uses

Outdoor and indoor furniture, decking, boat building, cabinetry, flooring, veneer, and turning.

Geographic Origin

Native to South and Southeast Asia; widely plantation-grown in Indonesia, Myanmar, India, Thailand, and Africa.

Workability

Machines and sands well, though silica and natural oils can dull blades and complicate gluing; pre-drilling is recommended.

Finish Recommendations

Clean and degrease before gluing or finishing. Use penetrating teak oil for a natural appearance, or compatible spar varnish/polyurethane for greater film protection.

Notable Features

Naturally oily, dimensionally stable, water-resistant, and often marked by dark mineral streaks; characteristic mild leathery scent when freshly cut.
