Rosewoo refers to a number of richly hued timbers, often brownish with darker veining but found in many different colors. All rosewoods are strong and heavy, taking an excellent polish, being suitable for flooring, furniture, turnery, musical instruments, billiard cues, and chess sets (the black pieces). In general, supplies are poor through overexploitation. Some species become canopy trees (to 30 m high), and big pieces can occasionally be found in the trade.
