This is just like an ordinary stone it's same size of soccer ball but this is so heavy it's like about 20kls. I've never encountered this type of stone in my life it is because it so heavy not like the normal stone. Anyone know what inside of this stone. Some foreigners said that it is diamond I don't know the exact name of the diamond it pronouns "Saysa". The owner don't want to open it, it is because every piece of this stone is worth money he said. I hope some knows here what kind of stone we have here. Thanks!
