Jade is a popular jewelry item that many people wear, but how many can truly tell the difference between good and bad jade? Let’s explore this in the following article. First, Burmese jade, also known as jadeite, has been highly valued in China during the late Qing Dynasty and early Republic of China. For instance, during the Qing era, a jadeite tube owned by Rong Lu, a high-ranking official, was worth 13,000 gold pieces. In the 1930s, a jadeite bracelet once sold for 40,000 silver dollars in Shanghai. This type of jade is known for its high hardness, bright luster, and vibrant colors, which make it highly collectible. Due to its beauty and value, it's often called the "King of Jade." It is cherished by many jade lovers, and countries like Japan and New Zealand even consider it their national stone. Because Burmese jade is mined nearby and processed mainly in China, Westerners often refer to it as China's "national jade."  Second, the color of Burmese jade varies depending on the region. In Myanmar, jadeite is categorized into three main types and twelve levels, while the domestic industry further divides it into over thirty grades based on color. The general color categories include: 1. White – free from impurities. 2. Red – contains iron (Fe³⁺), commonly known as "Fei." 3. Green – contains chromium (Cr), known as "Cui." 4. Black – contains chromium and iron. 5. Yellow – contains tantalum. 6. Purple – contains chromium, iron, and cobalt. The green variety is especially popular because of its vibrant color, durability, and universal appeal. It aligns well with the Chinese values of peace and gentleness, making it highly sought after. As a result, the price of high-quality green jade has skyrocketed, with some bracelets selling for over ten million yuan. Even smaller pieces of genuine A-grade jade can be extremely valuable if they have good clarity, craftsmanship, and color harmony. Third, the market is flooded with fake Burmese jade products. Due to limited supply and high demand, many merchants engage in fraud, producing fake stones and ornaments. There are four main types of Burmese jade products in the market: - **Class A** – Natural and untreated. Key identification features include fine texture, soft color, visible patterns, crisp sound when tapped, and a heavy feel. - **Class B** – Treated with strong acid and filled with resin. Initially looks good, but loses luster over time, becomes brittle, and sounds dull. - **Class C** – Artificially colored. Colors appear unnatural, and under magnification, the color is found in cracks rather than within the crystal. - **Class D** – Not real jade. Includes other materials like Thai jade, glass, or plastic. These are lighter, less hard, and lack the cold feel of real jade. For accurate identification, advanced technology such as high-magnification observation, density measurement, thermal conductivity testing, and infrared spectroscopy are required. Understanding these differences helps buyers avoid scams and appreciate the true value of authentic jade.
