Pernambuco wood is a dense and durable hardwood sourced from the Caesalpinia echinata tree, native to the coastal regions of Brazil. Known for its rich reddish-brown color and fine grain, it is highly valued for its use in crafting high-quality musical instruments, particularly violins and bows. This wood is also prized for its ability to produce a vibrant sound, making it a favorite among professional musicians. However, due to overharvesting and habitat loss, Pernambuco wood is now considered endangered, leading to strict regulations on its trade and use to ensure its conservation.
