1. Observation color: Jade and turquoise are mostly dark green or light green, but there may be other colors, such as white, purple and yellow. Authentic jade turquoise is full and uniform in color, with no obvious color difference.
2. Observe the texture: The texture of jadeite turquoise usually presents a fine spider web texture, which is called "Songhua". The finer and more uniform the texture, the more valuable the stone is.
3. Observe the transparency: Jade turquoise usually has high transparency and can transmit certain light. The higher the transparency, the more valuable the stone is.
4. Check the hardness: the hardness of jadeite turquoise is relatively high, generally between 6.5 and 7. Hardness testing tools (such as mineral hardness pens) can be used for testing.
5. Observe the luster: The luster of jadeite turquoise usually presents an oily texture, and the reflected light will have a certain luster. However, it should be noted that some processed stones may be polished and oiled to make their surfaces look more shiny.
6. Ask a professional to identify: If you are not sure about the identification of the original jade pine flower stone, it is best to consult a professional gemstone appraiser or jade expert, who has rich experience and professional knowledge and can accurately judge the authenticity and value of the stone.
It should be noted that the above methods are only preliminary identification methods, and the real professional identification needs more detailed observation and analysis.
