The charm size itself has not changed; however, from December 2026, new Resonate charms will feature an updated charm opening as part of an ongoing production update. The updated opening has been designed to remain compatible with all solid gold chain.
If you are adding new charms to an existing Resonate collection, they will continue to fit your existing chain; however, the bail size will differ from your existing charms slightly. If you have any questions, our friendly team is always happy to help.
