The Double-Sided Spring Clasp turns a small functional connector into part of the styling itself. Its elongated double-ended silhouette is designed to sit between a chain and the charms you want to wear, creating a clean focal point in either gold or silver.

Paired with an everyday chain, it gives you more freedom to change the look without changing the whole necklace. Add a favorite charm, mix different symbols, or build a combination that feels more distinctive and personal.

Wear it with a single charm for a cleaner look, or use it as the starting point for a more expressive layered combination.

To help maintain the finish of your jewelry, keep it away from prolonged moisture, perfume, lotions and household chemicals. Gently wipe with a soft, dry cloth after wear and store separately in a cool, dry place. For unplated sterling silver options, a silver polishing cloth may be used occasionally to refresh the shine. For gold-plated options, a silver polishing cloth is not recommended, as it may gradually wear the plated finish.

    This is smaller than it looks in the close-up photos, but the 20.7 mm length is enough to make it visible between the chain and charm. It feels more like a design detail than just hardware.

    I bought the silver version to switch charms between two chains. The double-ended mechanism makes the process much easier than opening tiny jump rings.

    At around 2g it has enough weight to feel solid without pulling the necklace down. I was worried the connector would feel bulky, but it does not.

    The gold version matches my plated chain pretty well. The tone is slightly softer than some of my older gold jewelry, so it may not be a perfect match with every piece.

    I like that I can change the charm without changing the whole necklace. It has made me wear a few pendants that were sitting in my jewelry box.
