Choose from a variety of earring backs for use with posts and ear wires, including best sellers and superior quality styles! Hypoallergenic options include sterling silver, karat gold fill, rubber, and nylon. You'll also find base metal earring backs including stainless steel, brass, bronze, and aluminum. Types of earring backings include butterfly nuts, earring stoppers, rubber-grip nuts (aka clutches), and mechanical-grip clutches. Wholesale prices are available when you buy in bulk. Choose your backs separately from your posts and hooks to get the exact match that works for you.
Having a tough time choosing?
If you need nuts for small sterling earrings, definitely get the sterling nuts; and for small 14kt or Gold-Fill earrings, then get the 14kt Gold-Fill nuts. After that, it gets a little trickier.
Stainless steel is strong, nicely priced, and keeps its color. But stainless steel nearly always contains nickel for strength, the springiness to grip your earring posts, and resistance to rust/corrosion. So if you are in the EU or are concerned about nickel allergies, move onto one of the non-steel options, such as aluminum. (more info about jewelry alloys and elements)
With or without flange? The flange (or disk) behind the ear helps keep large / heavy earrings upright and flat against the ear, instead of tilting forward with an awkward sag. Some people also say the flange makes it easier for them to put on and take off their earrings.
Rubber or mechanical grip?
The rubber grip is less expensive, and may be easier to fit onto a wider variety of post sizes. But eventually (in a few years or maybe a decade, depending on what it is exposed to) it breaks down and doesn't grip as well. For trendy fashions or delicate materials that won't be worn in 10 years, no problem!
The mechanical grip is a bit more expensive, but it fits all the posts we sell, has a nice springy grip that's easy to put on and take off, but holds well -- and it lasts pretty much forever. We have been selling these since the 1980's (do you remember the crazy big earrings we wore in the 80's?) and the old earrings in my jewelry box are still holding strong!
If you have it narrowed down to 2 different aluminum earring nuts with mechanical grip and flange, and they seem almost the same ... well, they used to be a bit more different from each other. With slight manufacturing changes over the years, to remove nickel (without adding other allergens, and still keep their durability, and be a good color match for common jewelry finishes), now they're almost the same. You will probably be happy with either option -- They're both good quality! However, the more-expensive one really is our customers' favorite for high-end earring earrings.
