Value & Age

Estimated Market ValueNot an official valuation

$15.00 - $30.00 per board foot, often sold by weight due to high density and CITES restrictions.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Based on the oxidation of the orange-toned areas and the depth of the checks/cracks, this sample is likely 5-10 years post-harvest.

Common Uses

Essential oil production (incense), turning, small specialty wood items, tool handles, boat bearings, and high-end carvings.

Geographic Origin

The Gran Chaco region of South America (mainly Argentina, Paraguay, and Bolivia).

Workability

Difficult to work due to extreme hardness and high oil content which can clog sandpaper and interfere with glue. Tends to dull cutting tools quickly but turns and polishes exceptionally well.

Finish Recommendations

Best left unfinished or with a light wax to preserve the natural fragrance. The high oil content makes film-finishes like polyurethane or lacquer prone to peeling or failure.

Notable Features

Highly fragrant with a sweet, citrusy scent when cut or burned. Known for its 'holy wood' ceremonial uses and high density (it sinks in water). Highly allergenic dust.
