Revealing the yellow wax stone fraud

Yellow wax stone has long been a prized item in Kistler's collection. The earliest excavated and most prestigious variety was Chaozhou Yellow Wax Stone. Later, Taishan Yellow Wax Stone gained fame, and this year Yunnan Yellow Wax Stone also rose to prominence. The latter two are considered "latecomers," with Taishan Yellow Wax Stone even being rebranded as "Taishan Jade," while Yunnan Yellow Wax Stone acquired the title of "Yellow Dragon Jade." Collectors can choose between natural ornamental stones or carved pieces. According to collectors, it is possible to distinguish real from fake yellow wax stone by observing its weight and color. Mr. Cao, a collector, explained that authentic yellow wax stone exhibits natural color transitions, which are hard to replicate in fakes. Additionally, resin-based imitations are much lighter. "This kind of fraud is actually easy to detect," one collector noted. The quickest and simplest method, according to some, is using fire. New forms of deception continue to emerge. For instance, some merchants alter the shape of uncarved natural ornamental stones to enhance their appearance. Mr. Cao, a collector from Chaozhou, mentioned that "hands-on" techniques often involve using a jade polishing machine to modify the surface. **Be Wary: Soaking in Oxalic Acid for Brighter Color** Whether it's a natural ornamental stone or a carved piece, one of the most common methods of falsification is soaking the stone in oxalic acid to make the color more vibrant. There are also coloring techniques similar to those used in emerald treatments. However, experts warn that this process is extremely damaging. "The stone may look beautiful at first, but over time, the surface layer gets destroyed, causing the texture to become loose and the surface to feel dry," an expert said. "A stone with a tight structure can maintain its oiliness for about a year, but one treated with oxalic acid needs constant oiling to preserve its appearance." **Mislabeling Heyuan Stone as Chaozhou Stone** Another common form of fraud involves hiding cracks in the stone. "For example, a high-quality yellow wax stone might be worth 10,000 yuan, but a cracked one could be valued at only 5,000. However, the crack may not be visible on the surface, leading buyers to pay 12,000 yuan and suffer a big loss," said a collector who had previously fallen victim to this trick. To avoid such losses, he recommends checking the stone with a flashlight to see through it. Additionally, some merchants glue broken pieces of yellow wax stone together, making it difficult to spot the damage. Another deceptive technique requires experience to detect. Many beginners have lost money due to this. Mr. Cao pointed out that different regions produce yellow wax stone with varying values. Some merchants take advantage by selling cheaper stones at higher prices. For example, Chaozhou Yellow Wax Stone with a large fist-like shape typically costs at least 10,000 yuan. Recently, Heyuan, a nearby area, also discovered yellow wax stone with a similar texture, but its market price for the same size is only 2,000–3,000 yuan. Some merchants then misrepresent Heyuan stone as Chaozhou stone. Mr. Cao advises newcomers to consult experienced collectors or "old hands" to avoid being deceived.
