Caviar stone, also known as bamboo leaf stone, is mainly produced in Yeyuan, Shijiahe, Mi Shan and other places in Shandong Province, and it is named because it has red, green and ochre colors similar to fish eggs or bamboo leaves.

There are few natural strange stones in fishseed stone. After processing and polishing, the background color of the stone is in sharp contrast with the color of the seeds on the stone, and the flower spots are rotten. The fishseed stone is calm in color and delicate in stone, which has high ornamental value.
