Round cable chain and flat cable chain are the same construction, different surface. Flat links have more surface area, which means more light interaction and more visible shine.
Stone Story
Continuous nacre deposition over an irregular surface, without interruption, builds greater thickness than most round pearl cultivation achieves. The result is the deep, orient-rich luster that makes fine baroque pearls genuinely unique.
Industry Insight
Historical precedent for the toggle mechanism exists across functional closures, but its adoption as a design-forward fine jewelry clasp came when the visible, architectural form of the T-bar and ring was recognized as an asset. It is one of the few closure types whose mechanism contributes actively to a piece's design rather than simply securing it.
