A silver ball stud is the earring you stop noticing. It goes in on Monday and is still there on Friday, through showers, work, the gym and a weekend wedding. That is exactly why the small details matter so much: the size of the ball, the length of the post and whether the metal is what the listing says. EVERU's version is a plain round ball on a post with a butterfly back, sold in 925 sterling silver in eight sizes from 3mm to 10mm. It sells at $13.99 for a pair, carries 4.5 stars from 1,471 Amazon ratings, and the listing says 100+ bought it in the past month.
Who buys a pair like this? The buyer excerpts tell you. People with a fresh first piercing, people with a second or third hole in the lobe, people whose job allows only a small stud, and people who simply want one earring they never have to think about. One buyer says these are "the only kind I can wear in uniform". Another bought them for a first-time piercing and came back for a second pair.
The one thing that decides this purchase is the number in millimeters. Size is the topic buyers argue about most: 80 mentions, of which 36 are negative. Some buyers say the ball was smaller than they hoped, one calls it tiny "like for an infant", and another says she ordered two sizes up and will now get it right. You can avoid most of that by translating the millimeter figure into something you can see before you order, which is what most of this review does.
A plain ball, a long post and a butterfly back
There is very little design to discuss here, and that is the point. The earring is a polished sphere on a straight post. The back is a butterfly clutch, which the brand story calls "Upgraded butterfly ear plugs" and says are "Securely worn and less likely to fall off". There is no stone, no texture, no hinge and no screw back. What you are paying for is the metal, the finish and the choice of size.
The brand states the metal plainly. The material bullet says the earrings are "made of high quality 925 sterling silver", and the product details in the brand story add "Hypoallergenic Non-tarnish, nickel free, lead free". The number 925 is the standard stamp for sterling silver, the solid silver alloy used for most silver jewelry. That matters because the cheapest silver-looking studs on Amazon are often plated base metal, where the silver color is a thin skin over something else. Sterling is silver all the way through, so there is no plating layer to wear off at the edge of the ball or along the post.

The listing's word "Non-tarnish" deserves a little skepticism. Sterling silver is an alloy, and silver alloys darken with air, skin and time. EVERU seems to know this, because the pack includes a polishing cloth. In practice, a polished ball that you wear every day tends to stay bright where it rubs against your skin and hair, and any dulling shows first on a pair left sitting in a drawer. Buyers who report on this so far are positive. One writes "Bright and no tarnishing so far", and another, who bought for a first piercing, says "no tarnishing or discoloration on the earrings".
What comes in the box
The packaging bullet lists the contents: two sterling silver stud earrings, one gift box and one polishing cloth. The package dimensions are 1.97 by 1.57 by 1.38 inches and 2.12 ounces, which is the weight of the boxed pair, not of the earrings themselves. The listing does not state the weight of a single ball in any size. If you are buying the 10mm as a gift, the box is small enough to fit in a card envelope or a stocking.
The post
Every size comes on the same post. The size bullet says "post length :10mm". Ten millimeters is a little under four tenths of an inch. That is a generous post for a stud, and it is the reason this earring causes more friction in buyer reviews than its simple shape suggests. A long post holds firmly in thicker lobes and leaves room for the butterfly back to sit without pinching. In a thin lobe, the extra length sticks out behind the ear, and that is where the complaints come from. We come back to this under comfort, because it is the most practical problem with the product.
Sizing: what 3 to 10 millimeters looks like
The brand story says EVERU offers "8 different sizes: 3mm -10mm" and adds a note: "our size is the international standard size, there is no bias large or small situation." In other words, the brand says a 6mm ball really is 6mm. The buyer complaints are not that the sizes are wrong. They are that people misjudged what a given number would look like on an ear. Millimeters are hard to picture, so here is the range converted to inches, next to what the listing and buyers say about specific sizes.
| Ball size | About, in inches | What the listing or buyers say |
|---|---|---|
| 3mm | 0.12 (about 1/8) | The listing calls it "even more compact and petite" and suggests it for keeping a piercing open overnight |
| 4mm | 0.16 | One buyer with thick lobes found the posts on the 3 to 4mm sizes too short |
| 5mm | 0.20 | No buyer comment in our data |
| 6mm | 0.24 (about 1/4) | No buyer comment in our data |
| 7mm | 0.28 | "Perfect size stud for me", with "a nice weight" and "terrific shine" |
| 8mm | 0.31 | No buyer comment in our data |
| 9mm | 0.35 | No buyer comment in our data |
| 10mm | 0.39 (about 3/8) | "Big enough to show up on an adult without being heavy" |
How do you choose? Start with where the earring goes. A second or third hole higher on the lobe usually wants the smaller end, 3 to 5mm, so the stud reads as a dot next to the main earring rather than competing with it. A single stud in a first hole has more room. Around 6 to 7mm, a ball starts to read as an earring from across a room rather than a glint. At 10mm, you are wearing a visible silver bead, roughly the width of a small pea. The buyer who chose 10mm says it shows up "on an adult without being heavy", which is a useful data point, since weight is the usual worry with large silver balls.

The chart above is the single most useful thing on the listing. It shows the sizes side by side on ears. Look at it with a ruler in your other hand, and you will make a better decision than most of the buyers who returned a pair.
The sizing complaints, read closely
Almost every negative size comment points the same way: too small. "Very small and cheaply made," says one. "They're fine just super tiny. Like for an infant, tiny," says another. A third, who kept hers as a backup, writes "Ordered 2 sizes up and will be perfect." A buyer who uses them every day still adds, "I think I did order the wrong size though, wanted smaller." So the mistakes run both ways, but more often toward a ball that looked bigger on the screen than it is in the hand.
The reason is probably the photography. Product photos of a single ball on white fill the frame, and a 3mm sphere photographed that way looks the same as a 10mm one. If you are unsure, our advice is to go one size larger than your first instinct for a main piercing and to stick with your instinct for a second hole. That is not a rule from EVERU. It is just what the pattern of complaints suggests.
Comfort, the post and sleeping in them
Comfort is a smaller topic than size, with 19 mentions, 14 positive and 5 negative. The positive side is what you would hope for from a smooth silver ball: "Nice and strong and don't hurt the ears," writes one buyer, and another says they are "not heavy in your ears."
The negative side is mostly about the post. Amazon groups ten mentions under "post length", and seven of them are negative. That is the worst ratio of any topic on this listing. Here is the problem in buyers' own words: "The stem is way too long, it pokes me and hurts if I try to lay down." Another is blunter: "Sleeping with them on is impossible. The posts are so long that they poke behind my ears and it's very painful."
This sits awkwardly next to the listing. The size bullet suggests the 3mm ball is small enough that "you can sleep without removing it" and recommends it for maintaining a piercing. The ball may be small, but the post on every size is the same 10mm. If you sleep on your side, the length behind the ear is what you will feel, not the size of the ball in front. One buyer with sensitive ears, who has worn hers continuously for a couple of weeks, sums up the middle ground well: "Occasionally, I've felt the length of the post when lying down."
There is a second, opposite comment. A buyer with what she calls "fat" earlobes found the posts on the 3 to 4mm sizes too short. That is hard to square with a single stated post length of 10mm across all sizes, and the listing does not explain it. It may be that the butterfly back sits differently on the smallest balls, or that her pair differed. Either way, it is worth knowing that the post question cuts both ways depending on your lobe.
| What the listing says | What buyers report |
|---|---|
| Post length 10mm on every size | Seven of ten post-length mentions are negative, most about posts poking behind the ear |
| The 3mm size is small enough to sleep in | Two buyers say sleeping in them is painful because of the post |
| Hypoallergenic, nickel free | One buyer with sensitive skin says "the silver is silver"; one says the studs started burning her ears |
| Non-tarnish | Buyers who mention it report no tarnish so far |
| Butterfly backs that are "less likely to fall off" | No buyer in our data reports losing an earring; one reports a ball separating from its post |
| Standard sizing, "no bias large or small" | Size complaints are mostly about choosing too small, not about wrong measurements |
Nickel and sensitive ears
If you have a nickel allergy, the advice is simple: look for jewelry with a stated nickel-free metal or a sterling silver or stainless steel base. This listing states both sterling silver and nickel free, which is as much as a product page can promise. Buyers with sensitive ears are mostly positive. One writes that they are "real, sterling silver as I'm sensitive to fake metals", and another says her ears "have not had a flare up" after two weeks of wear.
One buyer had the opposite experience and says the studs "started burning my ears". A single report like that cannot tell you whether the cause was the metal, the post, the piercing or something else, and we can't either. It is in the record, and it is one of a handful of negative comfort mentions out of nineteen.
Care and how they hold up
The listing gives no care instructions beyond the polishing cloth in the box. The cloth is the hint. Wipe the balls with it when they look dull, and keep the pair in its box rather than loose in a drawer, where other pieces can scratch a polished sphere. Since the listing describes solid sterling rather than a plated finish, there is no thin color layer to rub through, and polishing works on the metal itself.
Durability gets 22 mentions, 15 positive and 7 negative. The positive mentions are about a solid feel: "very nice and solid for daily wear," says the 10mm buyer. The most serious negative is a construction failure: "The ball on one of the earrings already fell off. I haven't even had these for two months." A ball stud is a sphere attached to a post, and that join is the only real weak point. One report among 1,471 ratings is not a pattern, but it is the kind of fault you should check for when the pair arrives. Hold the ball and give the post a gentle twist. It should not move.
Is it really sterling?
The material topic is where this listing takes its sharpest criticism. Of 22 mentions, 9 are negative. "These earrings are not sterling silver. This is fraud," writes one buyer. Another returned hers because "the finish on them looks like stainless steel and not pure 925 Sterling." On the other side, a buyer sensitive to metals is sure they are real silver and calls them "One of my top Amazon purchases ever."
We can't settle this from a listing, and we did not test the metal. What we can say is that a highly polished sterling ball and a polished steel ball look very similar in a photo and fairly similar in the hand. The finish comment does not prove the metal is fake. If authenticity matters to you, check the post or the back for a 925 stamp when your pair arrives (the listing doesn't say whether the earrings are stamped), and return them inside the window if you are not convinced.
What 1,471 buyers say
The star distribution is 78% five stars, 8% four, 6% three, 3% two and 5% one. That puts 8% of ratings at one or two stars, which is lower than many cheap jewelry listings and well under the level where a pattern of defects usually shows. Most buyers get a pair that looks right and wears well.

Topic counts as Amazon groups them on the product page, read November 14, 2026.
Read the topic counts in order of how lopsided they are. Appearance is overwhelmingly positive, 121 mentions to 11. Value for money is close behind at 38 to 4, and daily wear is 10 to 1. People like how these look and what they cost, and they wear them every day. The trouble is concentrated in three places: size (44 positive, 36 negative), material (13 to 9) and post length (3 to 7). Two of those three are about choosing well and knowing what you are getting, not about the earring breaking.
The stem is way too long, it pokes me and hurts if I try to lay down. Otherwise the quality is good.Amazon buyer
That second quote captures the typical complaint well. The buyer likes the earring and dislikes one specific feature. If you never sleep in your studs, the most common practical complaint on this listing may not affect you at all.
How it compares
Prices, ratings and monthly purchase counts as shown on Amazon search results on November 14, 2026. Highlighted rows are the products reviewed here.
These competitor rows come from an Amazon search for sterling silver ball stud earrings, and they include sets and single pairs, so the prices aren't strictly like for like. The obvious rival on volume is Obertis, at 4.4 stars from 9,179 ratings with 1K+ bought last month. It has six times EVERU's rating count at a slightly lower average. JEWELRIESHOP is the cheapest row on the table and has 6,030 ratings, but its 4.0 is the weakest average shown. KEZEF sits at 4.2 from 2,265 ratings, and Savlano at 4.4 from 745.
Two multi-pair sets are worth a look if you want several sizes at once. A three-pair set of sterling ball studs shows 4.5 from 106 ratings, and a three-pair set that mixes a 3mm ball with CZ and pearl studs shows 4.5 from 562. Buying several sizes in one order is a reasonable way around the sizing problem described above. ToHeart has 4.4 from 129, and Liya Gems has the top average on the table, 4.8, but from only 24 ratings, which is too few to read much into.
Where does EVERU sit? It shares the best average among the rows with a meaningful number of ratings, at 4.5, and it offers more single sizes than most listings in the search. It does not have the largest crowd. If you want the most-reviewed option, Obertis is the row to compare carefully. If you want to choose an exact millimeter size in sterling, EVERU's eight options are its real advantage. We can say nothing about competitors' metal or post length beyond their titles and numbers.
EVERU sells other pieces in the same sterling line, including druzy studs, gold-filled huggie hoops and drop earrings, which we cover in our EVERU earrings and necklace review. If you want ball studs for multiple piercings without a butterfly back, the Yoosteel jewelry review includes a six-pair set of flat back ball studs. The rest of our coverage is in jewelry. EVERU also lists this stud on its own site, on the EVERU ball stud earrings page.
Who should buy them, and who should skip them
Buy them if you want a single, plain silver earring you can leave in for weeks. They suit a second or third hole in the lobe, a uniform or workplace that allows only a small stud, and anyone who wants a gift that is hard to get wrong as long as the size is right. They also suit buyers who care about the metal, since the listing states 925 sterling silver and nickel free, and the polishing cloth means you can keep them bright yourself.
Choose the size with the chart open and a ruler nearby. For a main piercing on an adult, the buyer comments point toward 7mm and up if you want the ball to be seen. For a discreet stud or a higher hole, 3 to 5mm. If you are buying for someone else and don't know their taste, the middle of the range is the safe bet.
Skip them if you sleep on your side and hate feeling a post behind your ear. A 10mm post on every size is long, and the post-length topic is the one area where complaints clearly outnumber praise. Skip them as well if you need certainty about the metal before you buy rather than after, since a handful of buyers question whether the studs are sterling, and the listing doesn't say if they carry a 925 stamp.
Verdict
We recommend the EVERU sterling silver ball studs for anyone who wants a plain, everyday silver ball in a specific size. The case for them is simple: 925 sterling silver, stated nickel free, eight sizes from 3 to 10mm, a polishing cloth in the box and 78% five-star ratings from nearly 1,500 buyers at $13.99. We don't recommend them if you sleep in your earrings and have thin lobes, because the long post is the most consistent practical complaint. And whatever you do, don't pick the size from the product photo alone. Use the chart.
A good everyday silver ball, if you pick the size on purpose
The EVERU ball stud is plain sterling silver at a low price, and most of its 1,471 buyers are happy with how it looks and wears. The weak points are sizing by guesswork and a 10mm post that some buyers find too long to sleep in.
- 925 sterling silver, stated nickel free, with a polishing cloth and gift box in the pack
- Eight sizes from 3mm to 10mm, so you can match a second or third hole
- Appearance is the most praised topic: 121 positive mentions against 11 negative
- Low price for solid silver studs
- Size is the most disputed topic: 36 of 80 mentions are negative
- A 10mm post that several buyers say pokes them when lying down
- A few buyers doubt the metal is sterling, and one reports a ball coming off
- The listing has no size photo on a real ear beyond one chart
Best for: Anyone who wants a plain silver ball stud for daily wear, a second piercing or a uniform rule, and who will measure before choosing a size.
Skip it if: You sleep on your side in your earrings and dislike long posts, or you want a large statement ball and are unsure about sizing.
