1.5 x 1.5 x 6

Gaboon Ebony (Diospyros crassiflora) is one of the world's most prized exotic hardwoods, celebrated for its exceptionally dark heartwood, remarkable density, fine texture, and ability to achieve a beautiful, mirror-like polish. Often considered the classic black ebony, Gaboon Ebony is highly sought after by woodturners, pen makers, knife makers, musical instrument builders, and fine woodworkers.

Known for its deep black to dark chocolate-brown coloration, Gaboon Ebony offers a refined, luxurious appearance that few other hardwoods can match. Its dense structure, smooth texture, and outstanding polishing characteristics make it an excellent choice for custom pens, knife handles, bottle stoppers, decorative turnings, instrument components, and specialty woodworking projects.

Unlike striped ebony species such as Macassar Ebony, Gaboon Ebony is particularly valued for its dark, often nearly uniform black heartwood. Natural color variation, including dark brown and subtle streaking, may occur.

Every piece of Gaboon Ebony has its own unique character, making this exceptional African hardwood a premium choice for craftsmen seeking beauty, durability, and a distinctive finished appearance.

Botanical Information

Botanical Name: Diospyros crassiflora Hiern

Wood Type: Dense tropical hardwood

Primary Origin: West and Central Africa

Common & Trade Names

Gaboon Ebony, Gabon Ebony, African Ebony, African Black Ebony, Black Ebony, Genuine Ebony, Ebony Wood, Cameroon Ebony, Nigerian Ebony, and Diospyros crassiflora.

Origin & Distribution

Gaboon Ebony is native to tropical forests of West and Central Africa, including countries such as Cameroon, Gabon, Nigeria, Equatorial Guinea, and the Republic of the Congo.

The species grows in humid tropical forest environments and is known for producing extremely dense, dark heartwood.

Because Gaboon Ebony trees grow relatively slowly and the most desirable uniformly black heartwood is limited, high-quality material has long been considered a premium specialty hardwood.

Gaboon Ebony has historically been used for musical instruments, fine furniture accents, decorative inlays, carving, and other applications where a dense, dark hardwood is desirable.

Color & Appearance

Gaboon Ebony is renowned for its exceptionally dark heartwood.

Heartwood may display:

Jet black

Deep black

Dark chocolate brown

Blackish brown

Dark grayish brown

Occasional subtle brown streaks

The sapwood is generally pale cream, yellowish white, or light gray and contrasts sharply with the dark heartwood.

Some pieces may appear almost completely black, while others display subtle variations in color and grain.

The darkest, most uniform material is particularly desirable for premium woodworking and musical instrument applications.

Grain & Texture

Gaboon Ebony generally has a fine, even texture with grain ranging from straight to irregular or occasionally interlocked.

Common characteristics include:

Fine, uniform texture

Straight or irregular grain

Extremely dense structure

Small, inconspicuous pores

Smooth polished surfaces

Natural dark coloration

Its fine texture and high density allow Gaboon Ebony to achieve an exceptionally smooth finish, making it particularly desirable for small precision projects.

Wood Characteristics

Gaboon Ebony is an extremely dense and hard tropical hardwood with excellent wear resistance.

Representative characteristics for Diospyros crassiflora include:

Average Dried Weight: Approximately 60 lbs/ft³ (955 kg/m³)

Specific Gravity: Approximately 0.82 basic / 0.96 at 12% moisture content

Janka Hardness: Approximately 3,080 lbf (13,700 N)

Grain: Straight to irregular or interlocked

Texture: Fine and even

Natural Luster: Moderate

These values are representative of the species. Actual characteristics may vary depending on the individual tree, growing conditions, and moisture content.

Stability & Durability

Gaboon Ebony is valued for its exceptional hardness, density, and resistance to wear.

Its heartwood is generally considered durable, although its performance can vary depending on environmental conditions.

Like many extremely dense tropical hardwoods, Gaboon Ebony can be susceptible to checking and cracking during drying or when exposed to rapid changes in humidity.

Proper drying, storage, and acclimation are especially important for maintaining stability.

For small precision projects such as pens, knife handles, and musical instrument components, properly dried Gaboon Ebony can provide excellent long-term performance.

Workability & Woodturning

Gaboon Ebony is highly prized for premium woodturning and fine woodworking, but its exceptional density and hardness require careful machining techniques.

Sharp carbide or high-speed steel tools are recommended. Light cuts and controlled tool presentation can help minimize tear-out, chipping, and heat buildup.

Because of its density, Gaboon Ebony can dull cutting edges more quickly than softer hardwoods.

The wood is particularly well suited for:

Custom pens

Pen turning blanks

Knife handles

Knife scales

Bottle stoppers

Game calls

Duck calls

Decorative turning

Jewelry

Small boxes

Musical instrument components

Fine carving

Decorative inlays

Its fine texture and dense structure allow craftsmen to create crisp details and beautifully polished surfaces.

Finishing

Gaboon Ebony is known for its ability to achieve a beautiful, high-gloss finish.

Popular finishing options include:

Fine sanding and buffing

Hardwax oils

Shellac

Lacquer

Polyurethane

Cyanoacrylate (CA) finishes for pens

Wax finishes

Because Ebony can contain natural oils and extractives, some adhesives and finishes may require additional surface preparation.

A clear finish is generally preferred to preserve its natural black coloration and subtle grain characteristics.

Careful sanding through progressively finer grits followed by polishing can produce a smooth, luxurious appearance.

Ideal Uses

Gaboon Ebony wood blanks are excellent for:

Pen blanks and custom pens

Woodturning projects

Knife handles and knife scales

Bottle stoppers

Duck calls and game calls

Turkey call components

Decorative handles

Jewelry and accessories

Small boxes

Musical instrument components

Fingerboards and instrument accents

Decorative inlays

Fine carving

Specialty woodworking

Collectible and artistic projects

Health & Safety

Gaboon Ebony wood dust can cause irritation and allergic reactions in some individuals.

Ebony species have been associated with skin irritation, respiratory irritation, and sensitization.

Potential concerns include:

Skin Irritation: Wood dust may cause irritation or allergic contact dermatitis.

Respiratory Irritation: Inhalation may irritate the nose, throat, and respiratory system.

Eye Irritation: Fine airborne particles may cause redness and discomfort.

Sensitization: Repeated exposure may increase sensitivity in susceptible individuals.

When cutting, sanding, drilling, or turning Gaboon Ebony:

Use effective dust collection.

Wear properly fitted respiratory protection appropriate for fine wood dust.

Use safety glasses or a face shield as appropriate.

Avoid prolonged skin contact with accumulated dust.

Maintain adequate workshop ventilation.

Clean work areas using dust extraction rather than compressed air.

Because Gaboon Ebony is exceptionally dense, avoid excessive friction and heat buildup during machining.

CITES & Conservation

Gaboon Ebony (Diospyros crassiflora) is a conservation-sensitive hardwood due to its slow growth, limited availability of premium heartwood, and historical harvesting pressure.

The species has been assessed as Vulnerable on the IUCN Red List, making responsible sourcing particularly important.

Gaboon Ebony is not generally covered by the CITES listing for Madagascar Diospyros species, which applies to specific populations and species from Madagascar. However, international trade regulations, country-specific export restrictions, and applicable forestry laws should always be verified.

Buyers should confirm the botanical identity and legal sourcing of material when documentation is required.
