Great ifea


A tad spend your but my wife uses these with her expensive earrings. Very secure !


Never lose your precious earrings again!


I’ve lost 3 keepsake diamond earrings because the backs came off. I even lost an earring that had a screw back. I received my 4th pair for my 50th wedding anniversary but only wore the earrings for special occasions. I was so afraid I was going to lose this treasured gift from my husband. But, thanks to Chrysmela I’m now wearing my earrings everyday and I am confident these backs are amazingly secure and my earrings will remain on my ears. Unless I decide to take my earrings off. Thank you, best $50 ever spent!More > < Less


Time will tell


These seem great. Very secure. But only time will tell!


Innovative design make these earring backs a must!


I purchased 2 sets of Chrysmela's lock and secure earring backs, one pair in platinum ond one in yellow gold. I had lost a diamond earring from a screw- on post several years ago and was devastated. I finally purchased a new pair of diamond earrings. These earring backs are comfortable to wear and they are certainly not coming off by themselves! I am delighted with this product!More > < Less


Excellent earring clasps


My earrings have never felt so secure as they do with these clasps. Easy to put on and easy to take off, except not easy to accidentally fall off.More > < Less

About Chrysmela

Locked In Place

Chrysmela earring backs lock investment piece earrings and sentimental favorites in place so you don’t have to worry about losing them. They are made with gold- and platinum-coated surgical stainless steel to be long-lasting and to blend seamlessly with the look of high-end earrings.

Eri Kikunaga came up with the idea to make earrings more secure after a fight (and break-up) with a boyfriend over—you guessed it—a lost earring. The key to Eri’s fortified earring back design is nine precision-machined parts including three micro ball bearings that lock an earring in place. The back auto-adjusts to the post and will hang onto the notch in the post as an extra security measure.

The earring backs are made in Japan at a high-tech factories that also make smartphone cameras and watch mechanisms because Eri wanted her backs to be made to precision. That attention to detail results in an earring back that won’t budge—and that can provide lift for heavier earrings, too. With a pair of these backing up your earrings, you can wear favorite pairs with confidence that they’ll stay put no matter what you’re doing.
