Clasps such as spring rings and lobsters have a spring inside that will stick to a magnet. This spring is never precious metal. Precious metals are not "springy" enough to work inside clasps. The springs are spring steel. This is why spring rings can magnetically attract to the barrels of the converter. This does not affect the function of the converter.
