Is there anything more classic than a pair of diamond studs? They’re timeless and surprisingly versatile: A small, understated diamond can be an everyday staple, while a bigger stone can perfectly elevate a simple outfit. Ever since Molly Ringwald wore them in “The Breakfast Club,” we’ve been obsessed with diamond earrings. 

Fortunately, we have even more choice than ever before. In the past two decades, the diamond market has exploded with ethical, fair trade, and sustainable options. And, on top of that, direct-to-consumer brands allow for more reasonable prices since they sell right to you. But there’s now so much choice that you’ll want to look carefully at each brand to make sure they’re living up to the hype.  

When you’re on the hunt for the perfect pair, look for various certifications (more on that in a minute) to ensure your diamonds are being sourced responsibly. You’ll also want to prioritize brands that value the Four Cs (cut, color, clarity, and carat) for higher-quality stones. For an extra dose of sustainability, some brands use recycled metals or allow you to refurbish or return old pieces. Below, we’ve rounded up the most ethical, sustainable, and quality diamond studs, at a variety of price points. 

There are a few aspects to consider when you’re looking to buy a piece of diamond jewelry: 

• Lab-grown vs. natural: Lab-grown and natural diamonds are chemically, physically, and optically identical, but they differ in origin and cost. Natural diamonds, which are mined from the Earth, are more expensive and can often suffer from human rights issues. Lab-grown diamonds are created in a lab setting over a few weeks and are less expensive, but their resale value is lower. 
• Recycled metals: Some brands work with reclaimed precious metals, including silver, platinum, and gold, from sources including electronics, scrap metal, and even old jewelry. They refine the metals and use them to make new jewelry; this lowers the need for more mining and lowers the amount of emissions needed to create new pieces. Recycled metal can be recycled again! 
• The Kimberley Process: This global certification is designed to prevent “conflict diamonds” (i.e., diamonds sold to fund violent conflict) from entering the market. While it doesn’t cover every problematic aspect of sourcing, including human rights and labor abuses, it still establishes important controls on imports and exports.
• Conflict-free sourcing: Beyond the Kimberley Process, brands often use independent audits to track their diamonds from the mines (or labs) all the way to their stores. Systems like Everledger can also catalogue a diamond’s “journey” from origin to cutting, polishing, and transport. Lab-grown diamonds are innately conflict-free because brands know the labs making them. 
• Third-party certifications: A certification (a.k.a. grading report) for a diamond is an objective and independent assessment that measures the diamond’s qualities, including the 4Cs. Any reputable brand should make use of these certifications; without them, you can’t be sure of the quality. The certification should be obvious on the site and/or on the product page; labs include the Gemological Institute of America (GIA), the International Gemological Institute (IGI), HRD Antwerp, and the Gem Certification & Assurance Lab (GCAL).

These aren’t the only considerations, but they’ll at least ensure a level of quality and transparency that you might not find otherwise. If you’re curious, Brilliant Earth has a comprehensive guide to diamond quality, including the differences between lab and natural.

Should you choose natural or lab-grown diamonds?

There are different ethical considerations at play, so the answer kind of depends. Some brands have established robust processes to ensure that their natural diamonds are as ethically sourced as possible, but the stones still have a long supply chain: natural diamonds need to be mined, which requires more labor, causes more emissions, and can be tied to exploitative practices. 

Lab-grown diamonds, by contrast, start with a diamond seed and build real diamonds in a few weeks using either Chemical Vapor Deposition (CVD), which uses heated hydrocarbon gases, or High-Pressure High-Temperature (HPHT), which mimics the geological process of making natural diamonds. It’s worth pointing out that this process takes a lot of energy, so the carbon footprint depends on whether the lab is using coal or a renewable energy source. 

Ethical brands will often go out of their way to explain their processes, so look for their sustainability and sourcing pages — or, go in person to talk to a representative.

1. Brilliant Earth

Best For | Impressive ethics
Lab Grown Options | Yes
Prices Starting At | $150 for a single stud

Brilliant Earth has been making ethical fine jewelry since 2005 — they have been, in fact, a huge influence on the ethical diamond market and pioneered the notion of going “beyond conflict-free.” As such, their site is incredibly robust and allows for an experience that’s as close as possible to in-person shopping if you’re browsing online or aren’t near one of their showrooms. That includes 3D viewing, virtual try-ons, and skin-tone selectors to see how the jewelry will look on you, as well as the option to do a virtual appointment. They’re also particularly well-known for their “design your own” engagement ring platform, where you can browse diamonds, choose a custom setting, and size it perfectly — all online. 

Their diamond earrings run the gamut from starburst to olive branch, as well as different settings for more classic shapes. They structure their stud backs with intention, so that the stone doesn’t sag or tip over on your ear. Their bestselling perfect 4-prong diamond stud earrings offer a ton of customization: you can choose natural or lab-grown stones, start at 0.25 ct tw and go up to 4 ct tw for a natural or 8 ct tw for a lab-grown stud, and choose between white gold, yellow gold, and platinum. The free lifetime warranty is the cherry on top of the experience. 

Customer Review | “I’ve wanted a pair of professional studs that go with anything for a long time, and these fit the bill! I’ve even accidentally slept in them, and they were comfortable. Don’t catch on hair, haven’t dug into my skin, and sparkle even in low light. They’re big enough that they feel like proper earrings without being so big that they become statements in and of themselves.” – Ashley (Read more reviews.)

2. Kinn

Best For | Classic essentials
Lab Grown Options | Yes
Prices Starting At | $180

Kinn is an LA-based brand intent on making “modern heirlooms” with their pieces. It shows in their handiwork: they never plate their pieces and opt for vintage-inspired designs. Not only that, but they use conflict-free sourcing and emphasize traceability, so you can see and feel the quality. (You can also bring in worn 14k pieces for store credit, or reset your old jewelry!) 

Kinn has a great range of natural and lab-grown diamond studs, from simple round and emerald cut to more intricate designs like initials and crawlers. They also uphold all relevant grading standards which include, for lab-grown diamonds, GIA’s new refined “Premium” and “Standard” classifications. 

Their bestselling June studs run from 0.50 total carat weight (so, 0.25 per stud) all the way up to 3.0 if you’re hoping for a more weighty look. They come in a sturdy screw-back closure, which makes it much less likely you’ll lose an earring somewhere. The 180-day warranty is a nice touch if you’re feeling a bit unsure; virtual appointments are also available if you’re deciding between options or just want an extra hand in finding your perfect piece. 

Customer Review | “These earrings are absolutely lovely — bright, classic, and well-made. I’ve bought other items from Kinn and am always impressed with the beauty and craftsmanship.” – Katy H. (Read more reviews.) 

3. Bario Neal

Best For | Unique designs
Lab Grown Options | Yes
Prices Starting At | $300

Named after the last names of its female founders, Bario Neal is feminist fine jewelry with gender-neutral designs and 100% recycled and fairmined metals, all handmade in Philadelphia.

4. Mejuri

Best For | Everyday luxury
Lab Grown Options | Yes
Prices Starting At | $98 for a single stud

On the accessible luxury side, Mejuri empowers women to buy their own fine jewelry. At the same time, they’re pushing the industry to improve transparency around diamond sourcing and finding alternative options to improve affordability and quality (including, yes, lab-grown diamonds). They publish a sustainability report that highlights their suppliers, aims for transparency in their own processes, and demonstrates major stats — like the fact that the majority of their gold and silver is recycled. 

Mejuri has an entire diamond section of their website to help you peruse. Their earring collection is impressive, with tons of natural and lab-grown diamond studs at a variety of prices. There’s a variety of designs, too, with a focus on smaller carats (our editorial director particularly loves their pave diamond mini-hoops!). They’ve also got climbers, hearts, droplets, bars, and chain designs. So if minimal and delicate is your thing, there’ll be a lot to love on the site.

5. Holden

Best For | Complementary cuts
Lab Grown Options | Yes
Prices Starting At | $349 for a single stud

Handcrafting each piece in the New York Diamond District, Holden prides itself particularly on its wedding jewelry. They exclusively use lab-grown diamonds; they even offer a handy primer that goes into detail about the ethical and sustainable considerations that have led them to working with man-made diamonds. On top of that, all their jewelry is gender neutral, they give to important causes like The Trevor Project, and they’ve measured and compensated for all their carbon emissions since 2021.

Holden doesn’t have a dedicated diamond section, but a quick perusal of their earring collection reveals plenty of studs.

She LOVES them. The order was fulfilled right on time and it was easy to set up an appointment to pick the earrings up. The quality of the diamonds are beautiful and the settings make them absolutely shine.” – Tobias S. (Read more reviews.)

6. Quince

Best For | Affordable
Lab Grown Options | Yes
Prices Starting At | $98

You likely know Quince for their affordable basics at extremely reasonable prices; we especially love how transparent they are over sourcing and cost, and how they offer an apples-to-apples comparison of their products to other, more expensive brands. Their jewelry collection, originally launched in 2019 and expanded since then, has been met with approval by both consumers and editors (it made our list of best ethical jewelry for its affordability!). They use both natural and lab-grown diamonds and, by selling directly to consumers, are able to offer a similar quality of stone at a lower cost. 

Their diamond earrings are no exception to this. From the tiniest stud, $98 for a pair of 0.04 ct tw, to their largest option, which go up to 5 ct tw at $2,800, there’s an impressive price range within their small collection. There’s not as much variety as other brands on this list, but for basic studs, they’ve got you covered. If you happen to be in the market, they also offer a number of diamond hoops in different shapes and sizes. Quince offers free returns and exchanges for a full year after you’ve purchased!  

Customer Review | “This is one of those rare occasions when you get more than you pay for. These are excellent quality. Look amazing for such a tiny profile. Perfect for second-hole piercing.” – Alease M. (Read more reviews.) 

7. Aurate

Best For | Super small or XXL options
Lab Grown Options | Yes
Prices Starting At | $124 for a single stud

Founded in New York in 2015, Aurate is the definition of classic jewelry that also happens to be highly ethical. Co-founded by Sophie Kahn and Bouchra Ezzahraoui after they couldn’t find reasonably priced fine jewelry, the brand is responsive to customer feedback and committed to making pieces that people want to wear. On top of that, they pride themselves on sustainability, including sourcing diamonds from conflict-free nations and tracking them carefully. They use both natural and lab-grown diamonds, but they lean on the latter for ethical considerations. They also use the highest purity, including in the heavier diamond weights. On top of that, they use 100% recycled 14k or 18k solid gold, or alternatively 14k gold-plated vermeil.

Their dedicated diamond earring section offers impressive variety. Prices range from small lab-grown diamonds at only 0.06 ct tw at $248 for a pair to XXL bezel studs at 1 ct tw for $4,168. The cost is very reasonable, considering that their designs are unique and everything is crafted beautifully. Many of their items are made to order and offer impressive customization, including weight and metal color. 

Customer Review | “I got the 0.5ct total (0.25ct each) and for me they are the perfect size where they’re not too dainty so I can wear them on their own, but not too large so it is nicely stackable.” – Younju L. (Read more reviews.) 

8. Linjer

Best For | Delicate pieces
Lab Grown Options | Yes
Prices Starting At | $84 for a single stud

Linjer, which means “lines” in Norwegian, was founded by a Canadian-Norwegian couple who wanted to offer fine jewelry ethically and at low cost. All their diamonds are lab-grown, and they use 100% recycled 14k gold and 100% recycled 925 sterling silver in their pieces. The overall vibe is “dainty,” which makes it a nice pick for both affordability and pieces that work in your daily life. 

Their diamond earrings are particularly sweet and delicate. In addition to your standard tiny studs in a number of cuts, including round, pear, and cluster, they also have some beautiful chain designs. Their bestselling Helmi features four small stones hanging from a 14k gold chain — so if you like a softly draping piece but hate a larger chandelier style, this one’s perfect for you. Similarly, their Alva features four small diamonds in a star pattern with a small chain connecting the front of the earring to the back, mimicking a hoop style but with a softer shape. You also can’t go wrong with their teeny tiny Aria studs, which sit in a gorgeous three-prong setting and look substantial despite their small weight (0.034 ct tw).  

Customer Review | “These are really beautiful small studs. They have a pretty sparkle to them and are a great size. I have larger lobes and they suit so well. Very happy with this pair, I have been wearing them every day.” – Calyssa D. (Read more reviews.) 

9. GLDN

Best For | One-of-a-kind designs
Lab Grown Options | Yes
Prices Starting At | $74 for a single stud

Speaking of dainty: the female-founded GLDN focuses on small, everyday pieces that are subtle and stackable — and, simultaneously, fun and incredibly unique. You might know them best for their customizable necklaces (and customization in general), which is especially evident when you go to one of their retail locations. They have a ton of variety in chains and charms to create pieces that are bespoke to you. 

GLDN often works with less expensive stones, including white sapphires that have a similar look and feel to diamonds. They’ve also got a small diamond studs section, and even there the pieces are unique and visually interesting. Their Celeste diamond flatbacks include a tiny diamond set next to a pretty gold star (and are particularly reasonably priced); their Grace studs feature a round diamond on top of an emerald diamond; and, best of all, their Stargazer stud set include a diamond stud, a stud with a chain drop, and a bar stud — perfect for mixing and matching. When in doubt, though, you can’t go wrong with their Morningstar earrings: two small diamonds stacked on top of each other, and a perfect twist on the traditional stud. 

Customer Review | “These studs are everything I hoped for and more! I wanted a pair of diamond studs that were different and fun, and these are exactly that. I also didn’t want to worry about taking them out or them tarnishing. Not to mention they are super comfortable- the post length is perfect, they don’t stick out or poke in the back. Now I just need more piercings so I can order more!” – Kenzie K. (Read more reviews.)
