A semiprecious type of chalcedony, agate is a microcrystalline variety of quartz. It is made by a series of processes that happen in cavities within solidified lava. Most agate you'll see is banded & can be any color in the spectrum. 
 
This piece is simply amazing... It is a self standing piece & almost looks like it was glued together! When you turn it, you can see areas where the piece is translucent. It is a very cool piece!
 
Brecciated Agate is believed to have metaphysical properties to help one feel more secure. It also is known to make a person feel more calm when they are around it. I believe that this would be an amazing stone for a student it assists with concentration as well.
