Nephrite Donut bracelet

 Nephrite donut bracelets feature a central nephrite jade charm or bead carved into a donut or "Pi" disc shape, often strung on an adjustable cord or incorporated into a link bracelet. This design is rich in cultural symbolism and is valued for the gemstone's durability and perceived metaphysical properties. Bracelets often use high-quality nylon or cotton cords, which are usually adjustable to fit different wrist sizes. It is widely believed to attract good luck, friendship, and abundance while warding off evil spirits and negative influences.
