Purple sandalwood is generally more expensive than black sandalwood. This is due to several factors, including rarity, quality, and cultural significance. According to a report by the American Sandalwood Association, purple sandalwood is considered a premium material in the United States, commanding higher prices due to its limited availability and superior scent. Purple sandalwood trees are rare and often found in protected areas, which contributes to their higher cost. Additionally, purple sandalwood is highly valued in traditional Chinese medicine and for its aromatic properties, further driving up demand and prices. In contrast, black sandalwood is more commonly available and thus tends to be less expensive.
