Rosewood is generally more expensive than purple檀木. This is due to several factors, including the rarity of rosewood, its unique properties, and the demand for it in various industries.

Rosewood is a highly sought-after wood due to its rich color, fine grain, and durability. It is used in high-end furniture, musical instruments, and decorative items. The scarcity of rosewood species, which are protected under international agreements like the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), contributes to its high price. The demand for rosewood has been increasing, especially in Asia, where it is used in traditional crafts and furniture making.

Purple檀木, also known as sandalwood, is another valuable wood species. It is prized for its aromatic scent and is used in incense, perfumes, and traditional medicine. While purple檀木 is also rare and protected, it is not as highly valued as rosewood. The demand for purple檀木 is primarily driven by its use in religious and cultural practices, rather than its aesthetic or functional properties.

According to a report by the Forest Trends organization, the average price of rosewood logs in 2019 was around $2,000 to $3,000 per cubic meter, while the price of purple檀木 logs was approximately $500 to $1,000 per cubic meter. This significant price difference highlights the higher value placed on rosewood.

The rarity and demand for rosewood, combined with its unique characteristics, make it more expensive than purple檀木. Additionally, the legal restrictions on rosewood trade further contribute to its high price. While both woods are valuable, rosewood's status as a luxury material with limited availability ensures its higher cost in the market.
