Rosewood is significantly more expensive than ash wood. The price difference is primarily due to the rarity, endangered status, and the demand for rosewood in various industries, particularly in musical instruments and furniture making. According to the International Trade Centre, the price of rosewood can range from $10,000 to $20,000 per cubic meter, whereas ash wood typically costs between $200 to $500 per cubic meter. This discrepancy is further compounded by the fact that rosewood is listed on the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which restricts its trade and increases its value on the black market. Ash wood, on the other hand, is a more abundant and sustainable species, making it less valuable in comparison.
