Agate has a very long history. About 1 100 million years ago, due to crustal changes, underground magma erupted in large quantities. When lava cools, steam and other gases form bubbles. When the rock freezes, the bubbles are sealed and many holes are formed. After a long time, the pores were immersed in a solution containing silica and condensed into silica gel. Fusible components of iron-bearing rocks enter silica gel, and finally silica crystallizes into agate.
