Measure the widest part of the threaded portion of the earring post. Use a digital gauge/caliper to obtain accurate results. Our best trick to get them on or off is to simply hold the earring back firmly in one hand and turn your earring from the front into the earring back. This avoids hair from becoming twisted into the earring back. ​💎HIGH-QUALITY - Adora Fine Jewelry earring backs are quality die struck, which produces a much better quality earring back than die-cast. Die striking is a process of jewelry manufacturing that uses an immense amount of pressure and more gold to form a product of superior strength, shine, and durability. ​💎100% SATISFACTION GUARANTEE – We understand that there are several earring manufacturers and it is not possible to match ALL diameters and threading patterns.
