Rosewood refers to any of a number of richly hued timbers, often brownish with darker veining but found in many different hues. The timber trade will sell many timbers under the name rosewood (usually with an adjective) due to some (outward) similarities.All rosewoods are strong and heavy, taking an excellent polish, being suitable for guitars (specifically, the fret boards on electric and acoustic guitars are often made from rosewood), marimbas, recorders, turnery (billiard cues, fountain pens, black pieces in chess sets, etc.), handles, furniture, luxury flooring, etc. Rosewood oil, used in perfume, is extracted from the wood of Aniba rosaeodora, which is not related to the rosewoods used for lumber.In general, world stocks are poor through overexploitation. Some species become canopy trees (up to 30 m high), and large pieces can occasionally be found in the trade.The dust created from sanding rosewood is considered a sensitizing irritant and can trigger asthma and other respiratory ailments. Often, the more a person is exposed to rosewood dust, the more sensitive they can become to exposure.
