The main component of jadeite is sodium aluminosilicate, and the main component of nephrite is calcium magnesium silicate. The color and texture of jade vary depending on the mineral, and the common colors are white, green, yellow, purple, etc.
Second, the type of jade
There are many types of jade, and the common ones are jadeite, Hetian jade, Xiuyu, Dushan jade, etc. Jadeite is one of the most popular varieties of jade, mainly found in Myanmar.

3. Identification methods of jade
The identification of jade is a complex science, which requires comprehensive consideration of multiple factors such as color, texture, transparency, hardness, and specific gravity. Here are a few commonly used methods for identifying jade:
1. Observe the color: The color of jade is one of the important factors in determining its quality. High-quality jade has a bright and uniform color, delicate texture and high transparency. However, jade with dull color, rough texture, and low transparency is of poor quality.
2. Test hardness: The hardness of jade is one of the important factors in determining its quality. A common test method is to scratch the glass with jade, if there are scratches on the glass, it means that the hardness of the jade is higher.
3. Measure the specific gravity: The specific gravity of jade is one of the important factors in determining its quality. A common test method is to measure the weight of the jade with a balance, then place the jade in the water, measure its displacement, and calculate the specific gravity based on the displacement.
4. Check for imperfections: Defects in jade are one of the important factors in determining its quality. A common inspection method is to use a magnifying glass to observe whether the surface of the jade has cracks, blemishes and other defects.
Fourth, the maintenance method of jade
Jade is a precious gemstone that needs proper care to maintain its beauty and value. Here are a few commonly used jade maintenance methods:
1. Avoid collisions: Jade is a harder gemstone, but it is prone to cracks and blemishes when impacted. Therefore, when wearing and using jade, it is necessary to avoid colliding with items with high hardness.
2. Regular cleaning: The surface of jade is easy to absorb dust and grease, affecting its beauty and luster. Therefore, it is necessary to wash the surface of the jade regularly with warm water and a mild detergent, and then dry it with a soft cloth.
