Escamillo, the jacaranda you speak of is called "Jacaranda de Brasil." It is Dahlbergia nigra, to be specific, and is usually called Brazilian rosewood here. It has been used in fine guitars for a long time. It is more expensive than Indian rosewood.
The information above from thread 15038, especially a posting by Bill D. which provides a click to the USDA information sheets on this wood. Click to the thread: guitar woods
