This statement necklace includes three types of hand-knotted pearls, all natural color, plus a centerpiece of prong-set agate druzy. Druzy refers to gemstone covered with small crystals. When the crystals line a small opening in the rock, as here, that opening is called a "druzy vug". Not a lovely name, but a lovely effect! Adjusts from 18 1/2" to 21"
