The emerald necklace is composed of a series of repeating pear-shaped links, arranged closely together to form a wide, decorative front section. The design is symmetrical and fluid, giving it a graceful, draping appearance around the neckline.
At the center of each teardrop link is an oval-cut emerald, Each emerald is surrounded by multiple rows of  diamonds (pavé setting).
