Agate is formed by the deposition of silica-rich fluids in cavities within volcanic or metamorphic rocks. These cavities can be formed by gas bubbles, vesicles, or the dissolution of other minerals. As the silica-rich fluids fill the cavities, they slowly precipitate, forming concentric bands of chalcedony. The different colors of agate are caused by impurities in the silica-rich fluids.

Agate is creatively striped by nature during its formation over approximately 75 million years. It is made up of chalcedony quartz that forms in concentric layers in a wide variety of colors and textures. These colors have been enhanced to reveal their hidden beauty.
