Description
Made with certified recycled precious metal. Our silver, gold and platinum is refined from certified recycled content rather than newly mined ore, through refiners audited by outside parties.
How we source our metal
These sterling silver 9.0mm spring ring clasps feature an open top jump ring — meaning the top jump ring is not soldered closed — making them significantly easier to attach to chains without additional prep work. This open-top design is the most popular configuration among professional jewelers for its convenience and versatility.
If a fully closed top is required for a finished piece, the jump ring can be closed using a laser welder or spot welder. Important: never use a torch to solder the top ring closed. The heat generated by torch soldering will destroy the tension of the internal spring mechanism, rendering the clasp non-functional.
Features
- Open top jump ring for easy chain attachment
- Most popular spring ring style among professional jewelers
- Internal spring mechanism provides secure clasp action
- Open top can be closed with a laser welder or spot welder if needed
- Do not use torch soldering — heat will damage the internal spring tension
