Cocobolo (also called Cocobola, Caviuna, Funeram, Granadillo, Jacarandáholz, Nicaraguan Rosewood, Palo Negro, Pau Preto) is a tropical hardwood from the Central American Dalbergia retusa tree. Only the heartwood is used for woodworking purposes. It is reddish-brown and often features dramatic irregular figuring. The heartwood is so dense that some cocobolo will sink in water.
