So, I always had the notion that real, expensive Diamond earrings automatically came with screw backs. Especially from places like Blue Nile, James Allen, etc. I was sorely disappointed to find out that no, they do not. James Allen charges $125 just to change your posts from pushbacks to screw backs. I did a little Googling to find these, and they are a great alternative to spending $125 just to get what, in my opinion, should be included when buying earrings for the prices they charge. I definitely recommend these to anyone in conversation about earrings.

These earing backs do as they state. They lock onto the post where you place them and they won't move till you unlock to remove them. I bought my wife a very expensive set of earrings and she didn't want to wear them until they were protected from loss so we looked at all our options. We came across these and decided to try them out. I'm glad we did.

These catches are a work of art. I love the fact that they have a serial number associated with them. They clip on easily; you can hear going over the threads on the back of the earring. They are crafted in Japan. They do not bother the back of my ears; I never remove the earrings unless absolutely necessary. Thank you for a great product. Worth every penny!!!!!!!

I have had these earring backs for a couple of years, and love them. As someone who has lost innumerable earrings, these are life changing. Bought a pair for my daughter.

I've had "locking" earring backs before that didn't perform, but these are the real deal. Super impressed!
