This terra agate gemstone necklace with soft aqua blue stones is simply lovely! The polished round 8mm stones have brown and tan veins or markings--each gemstone is uniquely colored. This gemstone necklace has gold-plated brass star beads between each of the stones to separate them a bit so you can see the color variations. Because of the dark brown markings on many of the semi-precious stones, 2-4mm cultured flat freshwater pearls in a rich bronze color are spaced out between sections of the stones and gold beads. The necklace's length can be customized between 16 and 20 inches plus up to an additional 1-1/2 inches can be added with the gold-linked extension chain by placing the gold swivel lobster claw clasp in one of the links of the extension chain. As a finishing touch, dangling off the end of the extension chain is a skinny, elongated gold bead. You'll love this extension chain that gives you the ability to adjust the length just enough to work "just right" with your outfit's neckline.
