AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Fresh cut (less than 1 year). The light color indicates minimal oxidation, and the blade marks are prominent and sharp.
Common Uses
Incense, essential oils, small turnings, tool handles, carvings, and high-wear applications like bearings or bushings.
Geographic Origin
Gran Chaco region of South America (Argentina, Bolivia, and Paraguay).
Workability
Difficult due to extreme density and high oil content. Dulls blades quickly. Resins can interfere with glues and fasteners. Polishes to a high natural luster without much finish.
Finish Recommendations
Best left unfinished or with a light wax to preserve the natural scent. Solvent-based sealers are required if finishing is necessary to prevent oil bleed-through.
Notable Features
Powerful, sweet, citrusy fragrance that persists for years. Very high resin and oil content (Guaiac oil). The wood is so dense it sinks in water.
