According to the query of 7788 Collection Network and Paiyu Network, Chinese horseshoe crab agate is a precious gem condensed from the blood of Chinese horseshoe crab, with deep red or purple color and high transparency. The value of Chinese horseshoe crab agate mainly depends on the following factors:

1. The output of Chinese horseshoe crab agate is very rare, because Chinese horseshoe crab is an endangered species, and its number has decreased by more than 90%. The blood of Chinese horseshoe crab is secreted only when it is stimulated or injured, and the amount collected each time is very small.

2. The quality of Chinese agate is also very important, mainly color, transparency, shape, size and weight. Generally speaking, the darker the color, the better the transparency, the more regular the shape, the larger the size and the heavier the weight.

3. The market demand of Chinese agate will also affect its value, because Chinese agate is not only a beautiful gem, but also has many medicinal values and cultural significance. The blood of Chinese horseshoe crab contains a substance called hemocyanin, which can be used to detect bacteria and toxins. Chinese horseshoe crab agate is also considered as an auspicious symbol, which can ward off evil spirits and enhance human qi and blood.

To sum up, Chinese horseshoe crab agate is a very valuable gem, but the specific price depends on the market situation and individual differences. As far as I know, the price of one gram of Chinese horseshoe crab agate on the market is about 5000 yuan to 10000 yuan.
