Possessing an unusual green color and a dispersion greater than that of diamond, demantoid (which means "diamond like") garnets quickly became a treasured and expensive gemstone after their fairly recent discovery (late 1800's). They are the most valuable type of garnet and at their best have an emerald green color. This necklace contains demantoid rough garnet nuggets wire wrapped together with gold fill wire. Is your birthstone garnet, but you like green? Well this is your necklace! The nuggets are 5 to 6mm and the necklace is 16 inches long.
