At the heart of this ingenious system is a toughened grey gold blade, meticulously engineered to allow a rigid bangle to securely snap into a fully open position and stay open, or simply snap back into a closed position. This innovative spring hinge system not only offers practicality but also elevates the design of rigid bangles, enabling them to feature an open space between the ends. This creates a more airy, elevated look while adding an element of mystery to the piece—how does it stay in place? The secret lies in the precision-crafted spring hinge, which ensures a secure closure while maintaining a seamless aesthetic, making this design both functional and striking.
