Agate is a part of the large chalcedony family of minerals made of a microcrystalline variety of quartz (or silica). A single strand of agate beads may display everything from creamy white to a rich rusty red in striations or spots. We carry agate beads in a range of round sizes, faceted shapes, donuts and chips. All of FusionBeads.com's gemstone beads are graded AB. Learn all about gemstones in our Gemstone Q and A.
