The Herkimer Quartz “diamonds” on this cuff are rare, double-terminated quartz crystals. They are known as “diamonds” due to both their clarity and natural faceting. This cuff is extra special because it features some of the largest Herkimer specimens we’ve ever found. Wear this bracelet tight on wrist, or loose stacked with other bangles. Adjusts to fit most sizes.
