Diamond studs are the most classic earrings you can own, a single diamond in each ear that goes with everything and never looks dated. They are versatile enough for daily wear and dressy enough for a big occasion, which is why they are often a first diamond purchase and one of the most popular gifts. At MJ Diamonds, our diamond studs come in both men's and women's styles, in 10K and 14K white and yellow gold, set with real diamonds across a wide range of carat sizes.

Diamond Stud Earrings: Classic Studs for Men and Women
Choosing Your Carat Size
Stud carat weight is usually given as the total across both earrings, so a 1 carat pair holds about half a carat in each ear. Smaller sizes, around a quarter to a half carat total, are subtle and comfortable for everyday wear. A 1 carat pair is a popular sweet spot that balances sparkle and ease. Larger sizes, from 1.5 to 2 carats and up, make more of a statement for a special gift or occasion. Because studs are matched pairs, we hand-select the two diamonds to look balanced, and our team can show you sizes on the ear so you can see the real effect before choosing.


Settings: Prong, Martini, and Bezel
The setting shapes both the look and the security of a stud. A classic four-prong basket holds the diamond up and lets in the most light for maximum sparkle. A three-prong martini setting sits lower and more securely against the ear, a good choice for active wear. A bezel setting wraps the edge of the diamond in metal, the most secure and snag-free option, with a clean, modern look. Our jewelers can walk you through which setting suits your lifestyle, since a pair worn every day has different needs than a pair saved for occasions.
Diamond Shapes for Studs
Round is the most popular stud shape because it delivers the most brilliance and sparkle, but studs come in other shapes too. Princess cut gives a crisp, modern square look, and oval studs look a little larger for their weight. The best shape is the one that suits the wearer's style, and trying a few on is the easiest way to see the difference. Whatever the shape, the diamonds in our studs are genuine, and we are happy to go over their details in person.


Men's Diamond Studs
Along with our studs for women, we carry men's diamond stud earrings, usually a single stud or a matched pair in a clean, secure setting. Men's studs tend to favor round diamonds in prong or bezel settings that hold up to daily wear. If you are shopping for a man's pair or a single stud, our team can show you sizes and settings suited to everyday wear.
Real Diamonds and In-House Care
The diamonds in our studs are genuine, not cubic zirconia or simulated stones, set in real 10K and 14K gold. Because studs are worn often, our in-house jewelers can check and tighten settings, replace backs and posts, and keep them clean and secure, and we offer free jewelry cleaning at every location. That ongoing care is part of how we have served Michigan families since 1979.
