Lignum Vitae
Scientific name: Guaiacum officinale
Overview
Lignum Vitae is one of the densest and hardest commercial woods in the world. Native to the Caribbean, it has been historically valued for marine applications, bearing surfaces, and heavy-duty mechanical uses due to its exceptional strength, natural oils, and self-lubricating properties.
The name “Lignum Vitae” translates to “Wood of Life,” reflecting both its medicinal history and extraordinary durability.
Quick Facts
- Common Name: Lignum Vitae, Guayacan
- Scientific Name: Guaiacum officinale
- Region: Caribbean & West Indies Hardwoods (Caribbean and northern South America)
- Tree Size: 30–50 ft tall, 1–2 ft trunk diameter
- Average Dried Weight: 78 lbs/ft³ (1,250 kg/m³)
- Janka Hardness: 4,500 lbf
- Color: Olive green to dark greenish brown, often darkening with age
- Grain: Interlocked
- Texture: Very fine
Identification Characteristics
Lignum Vitae is easily identified by its extremely high density and distinctive color shift. Freshly cut heartwood appears olive green to dark greenish-brown, gradually aging to deep brown with subtle green undertones. The grain is typically interlocked, and the texture is very fine and smooth.
It feels unusually heavy for its size and often sinks in water due to its density.
Key identification traits include:
- Olive-green to dark brown heartwood
- Extremely high weight
- Very fine, smooth texture
- Natural waxy or oily feel
- Often sinks in water
Working Properties
Lignum Vitae is challenging to machine due to its density and interlocked grain.
- Requires sharp carbide tooling
- Can burn during cutting if tools are dull
- Difficult to glue due to natural oils
- Polishes to a very smooth finish
- Exceptional wear resistance
It has historically been used for ship propeller shaft bearings because of its self-lubricating properties.
Safety Note
Dust may cause irritation. The wood’s natural oils can interfere with glue adhesion, so proper surface preparation is required.
Common Uses
Lignum Vitae common uses including:
- Marine bearings
- Mallet heads
- Tool handles
- Turned objects
- Carvings
- Specialty mechanical parts
Historically used in naval shipbuilding and heavy industrial applications.
Sustainability & Notes
Guaiacum officinale is listed under international trade regulations due to historical overharvesting. Modern availability is limited, and sourcing should comply with CITES guidelines.
Collectors often encounter small turning blanks rather than large boards.
Comparative Notes & Related Species
Roughbark Lignum Vitae – Very similar in density and structure but often slightly lighter in tone and highly restricted in trade.
Ipe – Also dense and durable but lacks the natural oil content and green coloration.
Osage Orange – Dense and durable but noticeably lighter and more yellow-orange in appearance.

Collector Notes
True Lignum Vitae is rarely encountered in large dimensional lumber due to conservation restrictions. Most collector pieces are small turning blanks or reclaimed industrial components. Its exceptional weight and distinctive green-to-brown aging pattern make it immediately recognizable. Proper documentation of origin is important due to trade regulations, and older salvaged pieces often carry significant collector interest.
