First, the most direct way is to ask the merchant for a natural jade identification certificate, but the identification certificate may be fake. In this case, you need to learn the following method. 1. Look at the color of jadeite: Jadeite has a variety of colors, and several colors can coexist in a piece of jade. Overall, the green is unevenly distributed. Green appears in the form of dots, veins, strips, and spots on the white, while nephrite, South Sea jade, and serpentine jade are all relatively uniform in color. Among green tones, jadeite has the greatest variation in green, ranging from light to deep, bright to dark; and only jadeite has a bright green color. Other jade-like minerals do not have a bright green color unless they are artificially dyed. Dyed jade is made from inferior jade through chemical dyeing. Due to the dense texture of jade, the color can only stay on the surface of jade, so there will be an obvious floating feeling, and there is no color root inside the dyed jade.

Listen to the sound of jade: To identify a jade bracelet, you can hang the bracelet in the air with a thin rope, gently tap the bracelet with a metal rod, and listen carefully to the sound of jade to determine whether the sound is crisp and pleasant. The sound made when knocking processed jade is relatively dull, and requires careful listening to identify it. 3. Weigh the jade: natural jade has high density and large total mass. Hold the jade in your hand and weigh it gently, you will find that the jade has a noticeable feeling of heaviness. The processed jadeite is destroyed in its internal structure due to acid washing, and its density is reduced, thus its quality is also reduced. Compare it with a jadeite of similar size and feel the difference in weight. 4. Look at the luster of jadeite: The transparency of natural jadeite ranges from opaque to transparent. The surface of highly transparent jadeite has a glassy luster, and the surface of slightly transparent jadeite is smooth and warm. After the processed jade is pickled and transparent resin is added, if the quality of the jade is poor, it will have a waxy luster and lack water. 5. Look at the surface of jadeite: Use a magnifying glass to examine the surface of jadeite. You will find many tiny bumps and depressions of different sizes and directions on natural jadeite, but the transition between the bumps and depressions is smooth. This is the orange peel effect of jadeite. The processed jadeite is corroded on the surface due to acid washing, forming large cracks in the style of acid etching patterns.
