Agate is a common stone primarily made up of Chalcedony and Quartz in a wide variety of colors. Often formed in volcanic rock, Agates have been used in jewelry for thousands of years. These 6mm beads are polished, faceted and dyed green.
Semi-precious stone beads are mined all over the world and then are usually cut in China. They will often be dyed or color-treated to enhance their appearance. We select the best quality semi-precious that is available, and try to avoid finishes that are not durable. It is best to assume that some semi-precious beads will fade over time.
