Fine jewelry posts have long been made within a consistent gauge range, which is why clutch back replacement is rarely complicated. All you have to do is pick a metal color and if you want the standard or comfort fit.
Built For Ease
The post's diameter follows an industry standard that ensures consistent fit across backs from different manufacturers. In practice, this means the spring wings or threaded bore of a replacement back will engage the post correctly without modification, regardless of whether the back came from the same maker as the earring.
Gifting
Jewelry occupies a specific category in gifting because of its permanence. It doesn't get consumed, outgrown, or replaced casually. Ross-Simons has spent over seventy years helping customers find just the right thing for every occasion and price point.
