How to repair the fishseed stone?

Fish seed stone, also known as bamboo leaf stone, is mainly produced in Yeyuan, Shijiahe, Mishan and other places in Shandong Province. It is named because its red, green and ochre are similar to fish eggs or bamboo leaves. There are few natural stones in roe stones. 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 spots are rotten. Fish pebbles are calm in color and delicate in stone, which has high ornamental value.
