Jade, commonly referred to as jade jade or Burmese jade, is a type of gemstone known for its vibrant green (called "Cui") or red (called "Fei") color. While most ordinary jade holds limited investment value, high-quality jade can significantly appreciate in worth. However, only a tiny fraction—less than one ten-thousandth—of all jadeite is considered high-end collectible. Navigating the vast and colorful jade market requires knowledge, experience, and sharp insight. Here are some key tips for identifying real jade.
First, understanding "Cui nature." Some experts believe that natural jade differs from other types, including treated jade B goods. A notable feature of natural jade is the "green flash" or "fly wings," which refers to the sparkling effect caused by mineral crystals. However, not all natural jade exhibits this, and microcrystalline jade may lack it entirely. Therefore, the presence of "Cui" isn't a definitive sign of authenticity. High-end jade is rarer and more likely to be imitated, so caution is essential.
Second, the sound test. Although some sellers use the "ding" sound made by striking two bracelets to claim their jade is natural, this method isn't reliable. Certain natural stones like amphibole or "water foam" jade can also produce similar sounds. Moreover, some B-grade jade can mimic this sound, making it an unreliable indicator on its own.
Third, examining the texture. Acid-treated jade often shows visible pores and a rough surface. Natural jade can also develop similar textures through weathering, making it difficult to distinguish. Filling materials such as zeolites or clay may appear in natural jade, but these are not considered B goods and are easier to identify.
Fourth, grading jadeite. When confirming that a piece is natural, the 5C2T standard is used: Color, Clarity, Cut, Carat, Transparency, and Structure (Grain). High-end jade frequently commands extraordinary prices at auctions, leading to an increase in fake B and C grade products. This has created challenges for both buyers and professionals.
Fifth, jade identification certificates. Authentic natural jade (A-grade) will typically be labeled as "Jade," "Natural Jade," "Jade (A Grade)," or "Jade (Natural)." B and C grades are usually marked as "Jade (Processed)" or "Jade (Optimized)." While official certificates are generally trustworthy, there are counterfeit ones issued by unscrupulous organizations. Some may even issue identical certificates for different items or provide false certifications for profit. Always verify the certificate and the item carefully, and educate yourself to avoid being deceived. Knowledge is your best defense.
