Rosewood is generally more expensive than ebony. This is due to several factors, including rarity, demand, and legal restrictions. Rosewood is a highly sought-after wood due to its rich color, durability, and aesthetic appeal. It is commonly used in high-end furniture, musical instruments, and decorative items. The International Union for Conservation of Nature (IUCN) lists many species of rosewood as endangered, which has led to strict regulations on its trade. These regulations, along with the wood's popularity, drive up its price.

On the other hand, ebony is also a valuable wood, known for its dense, hard, and durable nature. It is often used in the making of high-quality musical instruments, such as pianos and guitars. However, ebony is more abundant than rosewood, and its trade is not as heavily regulated. This makes ebony more accessible and, consequently, less expensive.

According to a report by the Forest Products Journal, the average price per cubic meter of rosewood can range from $1,000 to $5,000, depending on the species and quality. In contrast, ebony prices typically range from $500 to $1,500 per cubic meter. These figures highlight the significant price difference between the two woods.

The rarity and legal restrictions surrounding rosewood contribute to its higher cost. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) regulates the trade of rosewood, and illegal logging and trafficking have further depleted its supply. This scarcity, combined with the wood's high demand, pushes prices up.

In summary, rosewood is more expensive than ebony due to its rarity, demand, and legal restrictions. While both woods are valuable, the unique characteristics and scarcity of rosewood make it the pricier option in the market.
