Moyu is a precious stone, and there are many cases of mixing real and false in the market. Identifying the authenticity of black jade requires a certain amount of professional knowledge and experience. Here are some common ways to identify black jade to help you identify the authenticity of black jade.
1.Appearance observation: First, observe the appearance characteristics of the black jade. Genuine black jade usually has a delicate texture, a smooth surface, and a warm feel. Fake black jade may have irregularities such as uneven color, rough surface, or obvious line marks.
2.Light transmission: Illuminate the black jade with a flashlight or strong light to observe its light transmission. Genuine black jade usually has a warm light transmission and is able to see some subtle textures and internal details, while fake black jade may appear dull or can see even patches of color through the light.
3.Density test: Real black jade is usually heavier and has a higher density. You can try to put the black jade into the water, the real black jade will sink to the bottom of the water, and the fake black jade may float on the surface of the water or sink uncertainly.
4.Temperature test: Touching the surface of the black jade with a thermometer, the real black jade will transfer heat more slowly and feel cooler to the touch. Fake black jade may transfer heat more quickly, and can feel noticeable heat after contact with the thermometer.
5.Sound test: Tap the ink jade with a fingernail or hard object, the real ink jade will produce a crisp and pleasant sound, similar to agate. Fake black jade, on the other hand, may make a dull or hollow sound.
6.Tactile test: touch the ink jade with your fingers, the real ink jade has a warm feel and a more delicate touch. Fake ink jade, on the other hand, may feel rough to the touch or be excessively smooth.
It should be noted that these methods are not completely accurate, and the identification of the authenticity of ink jade requires comprehensive consideration of multiple factors and judgment through various identification methods. If you plan to buy the best value of ink jade, it is recommended to consult a professional appraisal agency or personnel to get a more authoritative and accurate opinion.
