In the debate of rosewood versus ebony wood, ebony tends to be considered superior for several reasons. Rosewood, while prized for its rich color and grain, is subject to strict regulations due to its endangered status. Ebony, on the other hand, is not as heavily regulated and offers a more consistent quality and durability. According to the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora), rosewood species are listed as endangered, which restricts their trade and use in many countries. This not only affects the availability of rosewood but also raises ethical concerns regarding deforestation and habitat destruction. Ebony, while also a valuable wood, is not classified as an endangered species, making it a more sustainable choice. Additionally, ebony is known for its exceptional hardness and density, which contribute to its longevity and resistance to wear, making it ideal for high-quality musical instruments and furniture. Data from the Forest Products Laboratory at the United States Department of Agriculture (USDA) indicates that ebony has a Janka hardness rating of 2,320 lbf (pounds-force), significantly higher than rosewood's rating of 1,820 lbf. This hardness makes ebony more suitable for applications where durability is paramount.
