Lignum Vitae
Guaiacum officinale • Exotic/Tropical
Grain Pattern
Interlocked, very fine and tight; typically features a slight wavy pattern as shown in the grain shifts of the sample.
Color Description
Olive-green to dark brownish-black heartwood; sapwood is pale yellow. Notable for its waxy luster and significant color deepening upon exposure to light and UV.
Hardness Rating
4,500 lbf (Extremely Hard)
Durability Rating
Very Durable; extremely resistant to decay and insect attack due to high natural oil content.
Common Uses
Bearings, bushings, pulley sheaves, marine applications, tool handles, and turnery.
Geographic Origin
Central America and the Caribbean
Market Value & Sustainability
Estimated Market Value
$50.00 to $100.00 per board foot (often sold by the pound due to density).
Wood Age Estimate
5-10 years since milling; shows slight oxidation but lacks heavy aged patina or historical wear.
Sustainability Status
CITES Appendix II listed; IUCN status: Endangered. Trade is strictly regulated.
Workability
Difficult due to extreme density and interlocked grain; dulls cutters quickly. High natural oil content makes gluing problematic.
Notable Features
Oily/waxy feel; faint, perfume-like scent; sinks in water due to extreme density; naturally self-lubricating.
Finish Recommendations
Best left unfinished or used with thin solvent-based finishes like lacquer or shellac. Oil-based finishes may not dry properly due to natural oils.
Identification Confidence
Medium-High; identified by the characteristic olive-green hue, waxy luster, and tight interlocked grain patterns typical of Guaiacum species.
