Sold exclusively as a pair (set of 2). Replacement and upgrade earring stud backings, crafted in solid 14K gold, 18K gold, and platinum. Screwback: The most secure closure available. A threaded post pairs with a screw-on backing for travel, daily wear, and high-value studs where security is non-negotiable. Push Back: The classic friction-fit closure. Easy on, easy off, and a refined low profile against the lobe — ideal for everyday studs and gifting. All backings are produced to RockHer specification in solid precious metal — never plated, never filled. Compatible with most standard earring posts; for screwbacks, posts must be threaded. Each order includes one pair (2 backings). Quantity 1 = 1 pair.
