Chrysmela - Most Secure Earring Back with Support Disc, Yellow Gold, Hypoallergenic Earring Lifter for Diamond Studs and Pearls. Automatic Fit Lock and Lift

It works as described. There seems to be a locking mechanism built into this small earring back which could be unlocked by pulling a movable part at the end of it. It is not cheap, but seems to worth its price when the earrings are very expensive.

I must admit, I wanted to desperately protect my beautiful 16ct. blue topaz earrings. They were a gift. When I searched, these had thr best reviews. Although, I must admit I never thought I would pay $50 for earrings backs 😳. But i did, and thus far they are living up to the company's claim.I justified spending $50 for earrings backs, as an insurance policy. Losing my earrings, would be a greater financial and emotional lost, more than $50 dollars. But I have slept in them, several times, without issue. And they stand beautifully on the ear. Very secure. No movement or drooping.Yes, I would highly recommend.Spend the $50 to protect what you love.

These are the nest best earring backs I have ever used. Very secure with their locking ability. Also help studs to enhance the ear. These are the only backs I use. This includes the high end backs from investment type earrings and precious earrings passed down that are not replaceable due to their sentimental value. I highly recommend them.

I love the Chrysmela earring backs. My second pair arrived yesterday. Since I was so impressed with the Chrysmela catch high tech earring lock backs in platinum I purchased last year in February, I returned to purchase the "Lift and Lock replacement backs". They work great with my diamond earrings. They are well worth the price. The Chrysmela backs offer security and peace of mind with no fear of losing an earring, I considered them to be far easier to use than the screw on backs on many diamond earrings. As a result, I will have jeweler my jeweler remove the screw-on posts and replace them with regular posts that will work with the Chrysmela backs.

I have several of these for my better earrings. I don't worry about loosing earrings any more. They are easy to work (as long as you have some fingernails). Great product.

These worked extremely well for two years. Then a few days ago, I tried putting them on and one of the plastic disks broke in half. I tried to use it without the disk and the locking part didn't work at all. The other one, even though the plastic diskwas still intact, the lock didn't work on it, either. I don't know how they both stopped working at the same time, but that's what happened.I gave it four stars because they were perfect for two years, so figure that in if you decide to buy. They will cost you about $25 a year. If I only needed them for two years, I would have given them five stars.

I lost the back of my Cartier Love Stud earring. I tried other backs with no luck. Plus I did not want to pay $200 for a single earring back. These backs lock on and stay locked. Love them! They are perfect for expensive earrings

This product is not what is being claimed about it. I purchased it on Amazon had 3 wearings and one of the backs came completely apart. Bad choice for the money spent.
