Purpleheart, commonly known as peltogyne, amendoim, violet wood, amaranth and other local names (often referencing the colour of the wood) is a genus of 23 species of flowering plants in the family Fabaceae; native to tropical rainforests of Central and South America; from Guerrero, Mexico, through Central America, and as far as south-eastern Brazil.
The trees are prized for their beautiful heartwood which, when cut, quickly turns from a light brown to a rich purple color. Exposure to ultraviolet (UV) light darkens the wood to a brown color with a slight hue of the original purple. This effect can be minimized with a finish containing a UV inhibitor. The dry timber is very hard, stiff, and dense with a specific gravity of 0.86 (860 kg/m3 or 54 lb/cu ft). Purpleheart is correspondingly difficult to work with. It is very durable and water-resistant.
Purpleheart is prized for use in fine inlay work especially on musical instruments, guitar fret boards (Although rarely), woodturning, cabinetry, flooring, and furniture. The timber is also valuable in applications that require toughness, such as truck decking.
Exposure to the dust, generated by cutting and sanding purpleheart, can cause irritation and nausea, possibly due to the presence of dalbergione (neoflavonoid) compounds in the wood. This also makes purpleheart wood unsuitable to most people for use in jewelry. Purpleheart is also a fairly expensive wood, which is why it is usually used in smaller-scale projects.
