Cocobolo
Dalbergia retusa • Exotic/Tropical Hardwood
Grain Pattern
Straight to interlocked with a fine, medium texture; displays a rich, varied figure with dark streaks and occasional wavy patterns typical of Dalbergia species when turned.
Color Description
Heartwood ranges from orange to deep reddish-brown with darker streaks; sapwood is pale yellow. It features high natural luster and significant chatoyance; colors darken and mellow with light exposure over time.
Hardness Rating
2,960 lbf (Extremely Hard)
Durability Rating
Very Durable; highly resistant to rot, insect attack, and moisture due to extremely high natural oil content.
Common Uses
Fine furniture, musical instruments (especially woodwinds and guitar backs), turned objects (pens, bowls), knife handles, and decorative inlay.
Geographic Origin
Central America (extending from Mexico to Panama).
Market Value & Sustainability
Estimated Market Value
$50.00 to $90.00 per board foot (one of the world's most expensive and prized timbers).
Wood Age Estimate
Modern (likely 1-5 years post-manufacturing); the finish appears fresh with no significant signs of oxidation or wear common in vintage items.
Sustainability Status
CITES Appendix II listed; IUCN Red List status: Vulnerable. Subject to strict trade regulations and limited availability.
Workability
Difficult to glue due to high natural oil content; requires solvent (acetone) wiping before bonding. High density can dull blades quickly, but it turns and sands to a naturally high gloss.
Notable Features
Features a distinct, spicy floral scent when worked; oils can be a potent sensitizer/allergen for some people; naturally oily enough to require no finish.
Finish Recommendations
Carnauba wax, CA (cyanoacrylate) glue finish for pens, or simply polished raw. Avoid thick film-forming finishes like polyurethane which may peel due to oils.
Identification Confidence
High. The distinct reddish-orange hue, black linear streaks, fine grain, and oily luster are quintessential characteristics of Cocobolo used in high-end pen turning.
