Diamond Stud Earring Styles
Classic solitaire studs are the most iconic diamond earring—one diamond per ear in a simple setting. They're the earrings every jewelry collection starts with because they go with everything and never look dated. We sell more diamond studs than any other earring style, and customers wear them daily for years without ever taking them off. Halo studs surround a center diamond with a ring of smaller stones, which makes the earrings look significantly larger and adds extra sparkle. A 0.50-carat total weight halo stud can look like a full carat from conversation distance.
Three-prong martini studs use a tapered, cone-shaped setting that sits close to the earlobe and holds the diamond with just three prongs—minimal metal, maximum sparkle, and a clean profile from every angle. Bezel studs wrap each diamond in a smooth metal rim for a sleek, modern look that's completely snag-free. Cluster studs group several smaller diamonds into a single earring, creating the visual impact of a larger stone at a lower price point. And illusion-set studs use a polished metal plate behind the diamond to make it appear larger—it's an old jeweler's trick that still works beautifully.

How to Choose Diamond Stud Earrings
Total carat weight vs. each is the first thing to understand. When a pair of studs is listed as "1 carat," that's the combined weight of both diamonds—each stone is 0.50 carats. This catches a lot of first-time buyers off guard. We always clarify this because it matters: a pair listed as 1 carat total weight will look different from a pair with 1 carat each. Know what you're buying before you compare prices.
Cut quality is the most important factor in how your studs sparkle. Diamond studs sit right next to your face, catching light every time you turn your head, so a well-cut stone makes a noticeable difference. We recommend prioritizing cut over color and clarity for studs. Color in the G–H range looks white and bright without the premium of D–F grades. Clarity at SI1–SI2 is perfectly eye-clean in earring sizes—no one is examining your earlobes with a loupe. Matching matters too: both diamonds should be as close as possible in color, clarity, and size so the pair looks balanced on your ears.
Diamond Stud Earrings by Metal and Backing
White gold is our most popular metal for diamond studs because the neutral color disappears against the diamond and lets the stone do all the work. Yellow gold creates a warmer, more traditional frame that pairs naturally with warmer-toned diamonds. Rose gold adds a contemporary, feminine touch. Platinum is the premium choice—hypoallergenic, naturally white, and more durable for the post and setting. Pair your studs with a matching diamond pendant for a classic, everyday diamond set.
The backing type is more important than most people realize. Push-back (butterfly) backings are the most common—simple to use and secure for everyday wear. Screw-back earrings thread onto the post for the most secure hold; they're our top recommendation for expensive studs or active lifestyles because they won't accidentally slide off. La Pousette (guardian) backings use a spring mechanism that locks in place and sits flush against the earlobe, keeping the earring centered and secure. For diamond studs you plan to wear daily, investing in screw-backs or La Pousette backings is worth every penny.
Frequently Asked Questions
What is a good carat size for diamond stud earrings?
It depends on your style and budget, but the most popular range we sell is 0.50 to 1.00 carat total weight (0.25 to 0.50 per ear). That range gives you visible, everyday sparkle without being over the top. Quarter-carat total weight studs are delicate and understated—perfect for a first pair or for wearing alongside other earrings. One carat total weight starts making a real statement, and two carats total is a showstopper. We always recommend seeing a few sizes in person because studs look different on the ear than they do in a photo. Earlobe size and face shape both affect how big a diamond appears.
What does "total carat weight" mean for stud earrings?
Total carat weight (TCW or CTW) is the combined weight of both diamonds in the pair. So a "1 carat" pair of studs has two 0.50-carat stones, not two 1-carat stones. This is industry-standard labeling, but it trips up a lot of buyers who expect each stone to be the listed weight. Always check whether the listing says "total weight" or "each." If a listing just says "1 ct diamond studs" without specifying, it's almost certainly total weight. We always make this clear on our listings because it's one of the most common points of confusion in diamond jewelry.
Are screw-back or push-back earrings better for diamond studs?
For diamond studs specifically, we recommend screw-backs. They're the most secure option—the diamond literally threads onto the post, so it can't fall off accidentally. We've had customers lose push-back studs at the gym, in bed, or just during a busy day when the backing loosened without them noticing. With screw-backs, that doesn't happen. The trade-off is they take a few extra seconds to put on and remove. La Pousette backings are a good middle ground—they lock in place with a spring mechanism and are faster to use than screw-backs while still being much more secure than push-backs.
Can I wear diamond stud earrings every day?
Diamond studs are one of the few pieces of jewelry designed to be worn every day, all day. The diamonds themselves are the hardest natural material on earth, so they're not going to scratch or damage. The setting and post are small and sit close to the ear, so there's nothing to catch or snag. Most of our customers put their studs in and don't take them out for weeks or months at a time. The only maintenance is occasional cleaning—oils and lotion build up behind the stone over time and dull the sparkle. A quick soak and brush every couple of weeks keeps them looking brand new.
How do I clean diamond stud earrings?
Remove the backings and soak both earrings in warm water with a drop of mild dish soap for 10 to 15 minutes. Then use a soft toothbrush to gently scrub around and behind each diamond—the back of the setting is where oils, lotion, and dead skin cells collect the most, and that buildup is why studs lose their sparkle over time. Rinse under running water (plug the drain first or do it over a bowl) and pat dry. Do this every couple of weeks if you wear them daily. The difference between clean studs and dirty ones is dramatic. Also clean the posts and backings while you're at it—buildup on the posts can irritate sensitive ears.
