How Do These Creepy Eyeball Rocks Form?

The video explores the intriguing world of eye agates, discussing their unique appearance and formation process. Eye agates are formed when silica-rich fluid crystallizes in rock gaps, often in volcanic environments. Their distinct bands and colors result from variations in temperature and composition during formation. These rocks are commercially marketed as 'Evil Eyes' or 'Third Eyes' and are often polished or dyed to enhance their appearance. Despite their natural beauty, many agates in shops have been altered to resemble human eyes more closely.
