Sonora Sunrise is the name of the striking green, black, and red natural long stone that is centered between the other beads. This unique necklace of natural stones and pearls incorporates matte black abacus onyx, freshwater pearls, and amazonite that are on each side of the Sonora Sunrise stone.  There is a sterling silver toggle clasp centered at the back, and the length is 21" plus the featured drop that measures 2".  What makes this particular Sonora Sunrise stone stand out is the definite color banding, and the colors are beautifully saturated that show the chrysocolla. (green), cuprite (red), and iron (black), considered copper minerals.
