Jewelry Care
Proper jewelry care ensures your pieces stay beautiful for years. Clean your jewelry regularly using a soft cloth and mild soap solution. Avoid exposure to harsh chemicals, perfumes, or lotions. Store your items in a dry, cool place, preferably in a fabric-lined box or pouch to prevent scratching. Regular maintenance preserves their shine and longevity.

I bought for some really pretty diamondaire studs I purchased...way too small. Only good for very small studs. They were very pretty.

This fit my Diamond studs like a charm and give them that extra bling. My diamonds are not screw back so the post fit through the small jacket hole flawlessly. Stones any larger than 1/4 carat probably will not fit these though

If you're looking for sparkly earring jackets to enhance the look of simple studs, these are fantastic. Well crafted, nice heft, prong-set CZs are beautiful on the ear. They work great with my .41 each basket-set diamonds. Things to know: if you're putting a threaded post through them, you have to screw it on, just like the earring back. The jacket will accommodate no more than a half-carat stone (5.1 mm) if you want it to sit down inside. The basket of these jackets is cup like, better suited to a martini setting, but flat-bottomed mountings work fine, as well. For the price, WOW. They rival my real diamond jackets in beauty. I'm so glad I bought them, and would buy them again for gifting.

These look really nice and very real. I purchased them to wear with my 1/2 stud real diamond earrings and they would have looked great if they fit. The center hole - where the post goes through - is too small for my earrings post that have a screw on back. I tried other studs I have and I believe these would fit a normal post, just not the kind with screw on backs. For that reason I returned them.

These look really nice. My studs are handmade platinum in a martini setting, and they're thicker than standard studs. When I got these this wkend, I tried on one of my studs and everything was perfect. I loved them. I threw away all the packaging and put it in my jewelry box to be ready to wear. When I went to put them on this morning, only one stud fit. The other opening is too small. I tried switching out the earrings in case the difference was with my studs, but neither one fit in the one jacket. I will attach a photo for the one jacket that fit my studs. I really wish they both fit, and now I can't return because I threw away all the packaging
