These new chung dzi are quite beautiful. They are unetched, natural agate, with various patterns. We have a good supply of them, and will pick the most beautiful available for each order. It is widely believed in the Tibetan world that such beads protect against strokes. Whether or not that is the case, they are nice to wear, inexpensive, and make great gifts. We offered a few of them to Khampa friends during a recent visit to Tibet, and they received a very warm welcome. If you prefer a specific color of bead, please mention that in your order and we will pick the best one available for you.
