Today Cory shared some of his agate's with us. He goes searching for them with his Grandad. Sometimes they are really hard to find. Basically they are a special kind of rock that has been formed from lava. His Grandad cuts the rocks and polishes them. On the inside they can be translucent/milky/colourful.
