Mahogany is generally more expensive than sandalwood. This is due to several factors, including the rarity and demand for mahogany, as well as its versatility and aesthetic appeal.

Mahogany is a highly sought-after wood due to its rich, reddish-brown color and durability. It is widely used in furniture making, boat construction, and musical instruments. The demand for mahogany has been on the rise, especially in the furniture industry, which has driven up its price. Additionally, mahogany is listed on the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) Appendix II, which regulates its international trade to prevent overexploitation. This regulation has further increased the cost of mahogany, as it requires certification for legal trade.

Sandalwood, on the other hand, is valued for its aromatic scent and is used in perfumery, incense, and traditional medicine. It is also highly prized in certain cultures for its spiritual significance. However, sandalwood has faced significant overharvesting, leading to its listing on the CITES Appendix I, which bans international trade. The scarcity of sandalwood has driven up its price, but it is still generally less expensive than mahogany.

According to the World Wildlife Fund (WWF), the price of sandalwood can range from $1,000 to $2,000 per kilogram, depending on the quality and source. In contrast, the price of mahogany can vary widely but typically ranges from $2,000 to $4,000 per cubic meter. This price difference is due to the higher demand and rarity of mahogany compared to sandalwood.

In conclusion, mahogany is generally more expensive than sandalwood due to its higher demand, versatility, and the regulatory measures in place to protect it. While both woods are valuable and have unique properties, mahogany's status as a premium wood material makes it the more expensive option.
