FAQ
Will the gold color fade over time?
JGPT gold plating provides stable color consistency and surface quality.
Color longevity depends on wear frequency, friction, and environmental exposure.
Is the size measured by inner or outer diameter?
These jump rings are commonly referenced by outer diameter (OD), which aligns with traditional sizing practices.
Inner diameter (ID) is provided as a reference for compatibility when selecting chains or components.
Are these jump rings soldered?
No. These are open, unsoldered jump rings, designed for manual opening and closing during jewelry assembly.
Which size should I choose?
Selection depends on chain thickness, charm hole size, and required strength.
- Smaller sizes (e.g. 0.6 × 3 mm) are suitable for fine chains and subtle connections
- Medium sizes (e.g. 0.6 × 4 mm, 0.8 × 5 mm) offer a balance of appearance and strength
- Larger sizes (e.g. 1.0 × 6 mm) are recommended for heavier components and higher-load connections
Can these be used for bracelets?
Yes. All sizes are suitable for bracelets when selected according to chain weight and design load.
Larger wire thicknesses provide increased durability for frequently worn pieces.
What tools are recommended?
Two flat-nose or chain-nose pliers are recommended for clean opening and closing.
Avoid twisting the ring, as this may affect alignment.
Are these suitable for heavy or load-bearing designs?
Heavier designs require larger diameters and thicker wire.
For load-bearing or high-stress applications, selecting a thicker wire size is recommended.
