Yellow rosewood, also known as fragrant rosewood or Hainan huanghuali, is a rare and highly valued hardwood. Native to the lowland plains and hilly regions of Hainan Island in China—particularly around Jianfengling and Hanglu Mountain—it has been prized for centuries. During the Ming and Qing dynasties, it was the preferred material for high-quality hardwood furniture, especially among scholars and officials who appreciated its refined aesthetics and natural beauty. The wood is renowned for its stability, resisting warping, cracking, and bending. It is flexible enough to be shaped into intricate designs, such as curved legs or complex carvings. The heartwood ranges from yellow-brown to dark reddish or dark brown, with a rich, warm tone. Its grain patterns are distinct, often resembling flowing water, fox heads, or even "ghost faces," which add to its artistic appeal. This unique texture makes huanghuali furniture not only functional but also a masterpiece of craftsmanship. Huanghuali was widely used in the Ming Dynasty and early Qing Dynasty, with historical records like the Tang dynasty's *Herbal Supplement* describing its use in beds and other furnishings. However, overharvesting led to a severe decline in supply, and by the mid-Qing period, it became scarce. It was gradually replaced by other woods like rosewood. Despite this, some large pieces still exist, including single-panel cases that can measure up to two meters in length and half a meter in width. One of the key advantages of huanghuali is its natural oil content, which gives it a smooth finish without the need for paint. Over time, it develops a beautiful patina, deepening in color and luster. It is also resistant to decay and insects, making it extremely durable. These qualities have made it highly sought after by collectors and experts alike. Today, Hainan huanghuali is considered one of the most valuable woods in the world. Prices have skyrocketed, reaching up to 9,000 yuan per kilogram. In Beijing, some redwood enterprises offer gold bars in exchange for old huanghuali pieces, with 1 kg of wood being worth about 40 grams of gold. Internationally, the value is even higher—some antique huanghuali chairs in the U.S. are valued at millions of dollars. At a 2007 luxury exhibition in Wenzhou, a set of huanghuali furniture sold for 68 million yuan in a single day. While Hainan remains the primary source, Vietnamese huanghuali is also found, though it is less dense and more affordable. Recently, forestry authorities confirmed that both types are essentially the same species, just grown in different regions. However, due to limited supply and high demand, Vietnamese huanghuali is also becoming increasingly expensive. With export restrictions in place, the gap between the two is expected to narrow in the future. In summary, huanghuali is more than just a type of wood—it’s a symbol of Chinese craftsmanship, history, and cultural heritage. Its beauty, durability, and rarity continue to make it a treasure sought after by collectors and connoisseurs worldwide.
