Cocobolo is a tropical hardwood of Central American trees belonging to the genus Dalbergia. Only the heartwood of cocobolo is used; it is usually orange or reddish-brown, often with darker irregular traces weaving through the wood.
The heartwood changes color after being cut, and can be polished to a lustrous, glassy finish; being quite dense, sometimes having a specific gravity of over 1.0, it will sink in water. The sapwood (not often used) is a creamy yellow, with a sharp boundary between it and the heartwood.
Cocobolo is yielded by two to four closely related species of the genus Dalbergia, of which the best known is Dalbergia retusa, a fair-sized tree, reported to reach 75–80 ft (23–24 m) in height and 3 ft (0.9 m) in diameter; it probably is the species contributing most of the wood in the trade.(citation needed) Because of the high value of the timber, the trees yielding it have been heavily exploited, so they have become rare outside of national parks, reserves, and plantations. Only relatively small amounts of this prized wood reach the world market, and it is expensive.
