JGPT Jump Rings are organized as a defined size system, categorized by outer diameter (OD), with clearly specified wire thickness and inner diameters to support reliable and repeatable jewelry assembly.

This collection follows the JGPT Standard, ONESIKA’s consistency-focused gold plating system developed specifically for small structural components.

It emphasizes stable color, controlled gauge, and clean closures across production batches.

Together, these definitions ensure that each size functions predictably within modular jewelry systems, allowing designers to select components based on structure rather than trial and error.
