Product Description
This open jump ring is a standard jewelry assembly component designed for precise and reliable connections in fine jewelry construction.
With a 0.6 mm wire thickness and a 4 mm reference size, it is suitable for lightweight bracelets, fine chains, and small charms where a clean, minimal connection is required without adding unnecessary visual weight.
Finished with JGPT gold plating, this component provides consistent color tone and surface quality for everyday jewelry making.
The open-ring structure allows for flexible manual assembly while maintaining compatibility within modular jewelry systems.
This size is commonly used in designs that require subtle yet dependable connectors, offering slightly increased clearance compared to smaller jump rings while remaining visually discreet.

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.
