Agate is a naturally formed rock, most associated with ancient volcanic lava flows. The vivid color and distinct layers are apparent, especially viewed in front of a light source. This collection is made from pieces of genuine agate which are ground and polished inside a tumbler. The final stones are smooth, yet with slight variations from each other, giving the complete fixture its naturally textured appearance. Choose from various applications with multiple stone color and finish combinations.
