In diamond cut finishing, the facets are the metal. As long as the metal receives basic jewelry care, that's the whole maintenance story.
Built For Ease
Clutch backs come in sizes calibrated to post gauge and earring weight. Fine jewelry posts run standard gauge so you're usually working with a standard back. Heavier styles, however, have larger comfort-back options that actually hold the weight.
Made With Purpose
A friction back, also known as a butterfly or push back, is the most widely used post earring back. It has two spring-tension wings that grip the post when the back is pressed on, holding the earring in place without any locking mechanism. It's the default construction for most commercially produced post earrings.
