Jade is a type of jewelry that many people wear, but not everyone can tell the difference between good and bad jade. Let’s explore this topic further. First, Burmese jade, also known as jadeite, has been highly valued in China since the late Qing Dynasty and early Republic of China periods. For example, during the Qing Dynasty, a jadeite tube belonging to Rong Lu, a high-ranking official, was worth 13,000 gold pieces. In the 1930s, a jadeite bracelet owned by Tie Yuting, known as the "Jade King" in Beijing, was sold for 40,000 silver dollars in Shanghai. This type of jade is known for its hardness, clarity, and vibrant colors, which give it a calm and elegant appearance. Due to its high preservation value and aesthetic appeal, it's often referred to as the "King of Jade." It is cherished by jade lovers worldwide, and both Japan and New Zealand have even named it their national stone. Because Burmese jade is mined nearby and processed mainly in China, many Westerners believe it represents China's "national gem."  Second, the color variations of Burmese jadeite are diverse, influenced by different regions and mineral compositions. In Myanmar, jadeite is categorized into three main types and 12 levels, while the Chinese jewelry industry has further divided it into over 30 grades based on color. The general color tones include: 1. White: Pure white with no impurities. 2. Red: Contains iron (Fe³⁺), commonly called "Fei." 3. Green: Rich in chromium (Cr), known as "Cui." 4. Black: Contains chromium and iron (Fe²⁺). 5. Yellow: Contains tantalum (Ta). 6. Purple: Contains chromium, iron, and cobalt (Co). Among these, green jadeite is especially popular due to its vibrant color, durability, and universal appeal across different ages, genders, and social statuses. It aligns well with the Chinese cultural values of peace, gentleness, and harmony. As a result, the demand for green jadeite has surged, with prices rising dramatically—some bracelets now selling for over 10 million yuan. Even non-green jadeite jewelry, if genuine and of high quality, can be extremely valuable. Third, the market is flooded with fake and low-quality Burmese jade products. Due to limited natural resources and high demand, many unscrupulous merchants take advantage by producing counterfeit items. Fakes are common, even in Myanmar. To help identify real jade, there are four main categories: - **Class A** jade is natural and untreated. Key indicators include fine texture, soft color, clear patterns, and a heavy feel when held. These are rare and highly valuable. - **Class B** jade has been chemically treated to remove impurities and enhance transparency. However, it loses luster over time, becomes brittle, and may show cracks. - **Class C** jade is artificially colored. Under magnification, the color appears unnatural and fills cracks rather than being part of the crystal structure. - **Class D** includes imitations such as Thai jade, Australian green jade, or even glass and plastic. These materials are lighter, softer, and lack the cold, smooth feel of real jade. For accurate identification, advanced technology like high-magnification observation, density testing, thermal conductivity analysis, and infrared spectroscopy are necessary. While some basic methods can help, professional tools are often required to distinguish real from fake. Whether you're a collector or just curious, understanding these differences can help you make informed decisions when purchasing jade.
