Tree Agate is a variety of Dendritic Agate. The dendrite inclusions are usually green on a lighter or white base color. The dendrites form branch like patterns similar to the foliage in a tree. Our Cabochons are flat back, smooth domed stones. Each stone is a hand worked lapidary item, so natural variation in materials, cut and sizing may occur. No two are exactly the same, but that is also the charm of these stones.
