Quality problem, origin problem, market demand problem. 1, quality problems: there are defects, cracks and other quality problems in dangerous jadeite, so it is difficult to cut and polish it into high-quality jadeite jewelry in the process of finished product processing. The finished product is hard to process, and it is easy to crack due to internal defects, so it cannot be used. Compared with high-quality jadeite, the market value of dangerous jadeite is lower.

2. Origin: The price of jadeite in different places of origin is also different. If the jadeite mine is dirty, seriously polluted by industrial activities such as quarrying, or it is difficult to mine because of problems in the supply chain, the price will be lower, while the dangerous jadeite is generally the stone left after the mining of high-quality jadeite, and the price will naturally be lower.

3. Market demand: Market demand is also a factor that affects the value of dangerous jadeite. Compared with high-quality jadeite, the demand for dangerous jadeite in the market is not high, so it is naturally difficult to form high value.
