Power | Authority | Sovereignty The Conch Shell has served as the original trumpet since the beginning of time. Indian lore tells us that heroes of mythical warfare carried a mighty, white conch shell. Its blast is believed to banish negative energy, avert natural disasters and protect us from harm. Wear this charm for protection. Each charm hangs from Alex and Ani's Expandable Wire Bangle in a Rafaelian Gold Finish. Designed to wear alone, or to layer for a customized look, Alex and Ani’s patented Expandable Wire Bangle allows the wearer to adjust the bangle for a perfect fit. Each bangle is adjustable down to two inches in diameter and expand to about three and a half inches in diameter. The average circumference (when they are delivered) is about seven and a half inches.
