Lab-grown and natural are both diamond, the same carbon crystal, and your eye cannot tell them apart. They are priced differently: buy a lab-grown diamond to wear, since some jewelers do not take it in trade.

Every purchase comes with our official appraisal: the carat and gram weights, the diamond grade and the color.

Visit the showroom on 47th Street: text or call 212-872-9692 before you make the trip.

Diamond stud earrings for men and women, most of them lab-grown diamonds in 14K gold, from 0.20 to 10 carats total weight, in round, Portuguese, Asscher, princess, emerald, oval, radiant and heart cuts. A few pairs are natural diamonds, chiefly Asscher cuts. Where a listing prints the grades, most read E or F color and VS1 clarity.

“Choose lab-grown if you want the look. Choose natural if the piece is meant to be passed down to someone you love.” Trax, at the jewelry store on 47th Street

31 pairs, most of them lab-grown in 14K. One carat a stone was the size bought most, 6.5 mm across.

Buyer's guide

How to choose diamond stud earrings

Pick the size of each stone, then grown or mined, the gold, the back and who wears it

Decide the size first. One carat a stone is the pair most people picture, and it was the size bought most here. Take it in 14K gold, grown or mined, in yellow or white to go with the gold you wear most. A round stone is the safe cut. Before you pay, ask us which back the pair wears, since no listing says.

See your stud size on your ear

The stones below are drawn at their true size: on most phones right away, anywhere once you check the screen with a quarter. Pick a size; to see it on you, hold the phone beside your ear in a mirror.

1. Check the screen with a quarter

Lay a quarter flat on the screen, over the coin, and move the slider until the coin on the screen is exactly the size of yours.

2. Pick a size, carats a stone

A 1 carat round diamond measures about 6.5 mm across. 5 of the 26 stud pairs here that name a weight are 1 carat a stone, 2 ctw the pair. It is the most bought size here: 39 percent of the stud pairs sold here in the past year that name a weight.

Stud earrings are sold by ctw, the total weight of the pair: half of it sits on each ear, so a 2 ctw pair is two stones of 1 carat. The stones are drawn as round diamonds; at the same weight a princess or emerald cut looks a little smaller and an oval or pear a little longer.

The stones are drawn as round diamonds by our rule of thumb for a well-cut round of that weight, not a listing's measurement. The pairs are the listings live here on September 26, 2026 that name a weight; the most bought size reads the stud pairs sold here in the year to September 25, 2026 that name a weight.

Carats and millimeters: what size diamond studs to buy, and how big 1 carat looks

Start at one carat a stone. It was the size bought most here, and about seven pairs in ten sold carried that much or more. The ctw on a title counts both ears, so halve it for each stone. On the lobe, a stone that size sits about 6.5 mm wide and shows plainly across a table. Half a carat stays small and quiet. From two carats a stone, the diamond fills much of a small lobe. An oval or a pear spreads wider than a round of the same weight, while a princess or an Asscher looks a little smaller. The table runs every size.

Lab-grown or natural: lab grown diamond stud earrings or natural diamond studs

Grown or mined is your choice. A grown diamond is the same carbon crystal as a mined one, graded the same way. Grown lets you go a size bigger, and mined is the rarer stone. Lab-grown and natural diamonds of the same grade look the same; a natural diamond costs more. We don't sell diamonds as an investment, and resale value isn't guaranteed for either. More than four pairs in five here are grown, all in 14K. Two Asscher pairs say natural in their titles. Three more pairs read natural on their origin line. The lab-grown and natural guide shows how a jeweler tells them apart.

The gold: 14K white, yellow or rose gold diamond studs

Buy 14K. It is hard enough to keep the prongs tight on a stone you never take out, and every grown pair here is made in it. Only four pairs are 18K. Choose the color on the listing. Most pairs offer yellow, white and rose, and the fancy shapes, from the oval to the butterflies, come in yellow or white. Yellow and white sold close to evenly, and rose was about one pair in twenty. White gold makes a colorless stone look whiter, and yellow warms it slightly.

The back: screw back or push back diamond stud earrings

Take a screw back on studs you sleep and train in. It is a small nut that turns onto a grooved post and cannot slip off. A push back is a clutch that presses on in a second, handy for a pair you take out each night, but its grip weakens as the months pass. The listings here do not say which back a pair ships with, so ask us, and ask whether we can fit the other kind.

Men or women: diamond stud earrings for men, for women and as a gift

A diamond stud is the same earring on any ear. Most pairs here sit in both our men's studs and our women's diamond earrings, and those guides go further into cuts and styles. Seven pairs, the butterflies and the heart among them, sit only in the women's case. On a larger lobe the same stone looks smaller, so many men go up a size. For a gift, take a round pair in 14K white or yellow gold.

Every count on this card is from the 31 pairs live here on September 26, 2026 and what this page sold in the year to that day; prices are on the listings. Across is the usual width of a round stone of that weight. Seven pairs do not say how big each stone is and sit outside the rows.

Questions we get in the store

What size diamond studs should I buy?

Take one carat a stone if you want the size most people picture. It sits about 6.5 mm across, and it was the size bought most here. For a smaller pair to wear every day, go to half a carat a stone, near 5 mm.

Is a lab-grown diamond stud the same stone as a mined one?

The crystal is the same carbon as a mined stone's, and only a lab machine can tell the two apart. Most pairs here are grown.

What does ctw mean on diamond stud earrings?

It means carat total weight, both diamonds counted as one number. Halve it for each ear, so a 2 ctw pair wears a one-carat stone on each side. Two titles here say only ct, so ask us whether that is the pair or one stone.

Which back holds a diamond stud best?

A screw back holds best. Its nut winds down the post and stays on through sleep and the gym, where a push back works loose with time. No listing here names its back, so ask us which one a pair has.

White, yellow or rose gold for diamond studs?

Match the gold you wear most. Yellow and white sold close to evenly here, and rose trailed far behind. Most pairs let you pick any of the three golds on the listing, and the fancy shapes come in yellow or white.

What color and clarity are these diamonds?

Where a pair prints its grades, they read E or F color and VS clarity nearly every time, colorless to the eye and clean without a loupe. Many listings print no grade, so ask us for it before you buy.

Are these diamond studs for men or for women?

Both. The same pair suits either ear, and most of these sit in our men's and women's cases alike. The butterflies and the heart are made for her. A man with a larger lobe often goes a size up, since the stone reads smaller there.

Can I return a pair of diamond studs?

Yes, inside fourteen calendar days of delivery, for studs never worn or altered. Clear the studs' return with customer service at service@traxnyc.com or 212-391-3832; they travel only on our return label. A five percent restocking charge and the return shipping come off, per the refund policy. Custom pairs are final.

Diamond Stud Earrings for Men and Women, Lab-Grown and Natural

The carat figure on a pair, written ctw, adds the two stones together, so halve it for one ear. Round is the classic look; a Portuguese cut carries many more facets for extra sparkle; Asscher and emerald cuts are step cuts with a cleaner, mirror-like face. The diamond stud earrings guide shows how big each size looks on the ear.
