Ebony (most likely Gaboon or African Ebony)
Diospyros crassiflora • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly interlocked with a very fine, uniform texture. Pores are small and usually filled with dark mineral deposits, making them nearly invisible to the naked eye.
Color Description
Jet black to dark brown heartwood, occasionally with grey or dark brown streaks. The sapwood is typically a pale yellow but is not present on this fingerboard. It has a high natural luster and develops a deep, silky patina with use.
Hardness Rating
3,220 lbf (Extremely Hard)
Durability Rating
Very Durable. Highly resistant to rot, insects, and moisture; specifically chosen for fingerboards due to its resistance to wear from metal strings and perspiration.
Common Uses
Musical instrument fingerboards, piano keys, pool cues, high-end knife handles, turned objects, and inlay work.
Geographic Origin
Western Africa (primarily Cameroon, Gabon, and Congo).
Market Value & Sustainability
Estimated Market Value
$100.00 - $150.00 per board foot (depending on the degree of jet-black color and absence of streaks).
Wood Age Estimate
The instrument appears modern and well-maintained. The wood itself is likely from a mature tree (200+ years) but was processed and installed within the last 5-15 years based on the string condition and finish luster.
Sustainability Status
IUCN Red List: Endangered. Not currently CITES listed, but strictly regulated due to over-exploitation. FSC-certified ebony is rare but available through specific sustainable management programs.
Workability
Difficult. Its extreme density and high oil content cause rapid dulling of tool edges. It is prone to checking and splitting during drying, but it sands well and takes a high-natural polish without the need for extensive finish.
Notable Features
Extremely heavy (it sinks in water). Known for its high compressive strength and clear acoustic resonance. Some users report skin irritation or respiratory sensitivity to the fine dust.
Finish Recommendations
Often left natural or finished with light applications of mineral oil or lemon oil to prevent cracking. Does not require lacquer or polyurethane due to its high density.
Identification Confidence
High. The jet-black color, lack of visible grain/pores, and use as a fingerboard on a violin-family instrument are diagnostic for African Ebony.
