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.

How to buy women's diamond stud earrings
Choose the carat first and see how big it sits on the ear, then pick the stone and back
Settle the carat before anything else, because how big the stud sits on the ear follows from it. On a stud, ctw adds both ears together, so a 2 ctw pair puts one carat on each lobe, and that is the pair bought most here. Take it lab-grown and round, in yellow or white gold. The listings rarely say which back a pair wears, so ask the desk before you pay.

See your stud size on your ear
Set your screen once with a bank card and the stones below are drawn at their true size. Pick a size; to see it on you, hold the phone beside your ear in a mirror.
1. Set the screen with a card
Lay any bank, debit or ID card flat on the screen, standing tall, so its short edge runs across the box, and move the slider until the box is exactly as wide as the card. No bank card? A driver's license, metro card, gift card or hotel key is the same size.
Set on this device already; move it only if the box and your card differ.
2. Pick a size, carats a stone
A 1 carat round diamond measures about 6.5 mm across. 7 of the 30 stud pairs here that name a weight are 1 carat a stone, 2 ctw the pair. It is the most bought size here: 38 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 25, 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.

Questions we get in the store
What size diamond studs should I get?
Get 2 ctw, a carat in each ear, the pair most buyers here chose. It measures about 6.5 mm across. The biggest pairs reach about 8 mm. Ask the desk whether a listed width is the stone or the whole setting.
Lab-grown or natural diamonds for stud earrings?
Lab-grown, for most buyers here. It went into about six pairs in seven. Both are real diamond, one grown and one mined, and the mined stone is scarcer. Every silver pair is lab-grown. Every diamond pair names one on its listing.
Is the carat on diamond studs per ear or for the pair?
For the pair, when it reads ctw. A 2 ctw pair is two one-carat stones, one on each lobe. When a listing says each, the figure is a single stone, so double it. With no carat printed, ask the desk for the total.
More questions we get
Round or Portuguese cut diamond studs, what is the difference?
The outline is the same and the facets are not. A Portuguese cut adds rows of facets, so it breaks the light into more small flashes, and a round gives the classic sparkle. Round sells most here, and Portuguese is the next cut by the pair.
Can diamond studs reach her in time for a wedding?
They can, if the pair shows In stock by its price. Those usually leave within two to five business days, and a pair made to order is slower. For a wedding, give the date to the live chat first, text it to 212-872-9692 from 10 AM ET, or add it to a checkout note.
Screw back or push back for diamond studs?
A screw back, for a pair you never take out. It turns down a threaded post and stays. A push back comes off faster but loosens sooner. Listings seldom say, so ask the desk which one yours has and whether it can change.
How much are diamond stud earrings for women?
The price is on each listing. The carat moves it most, then lab-grown or natural, then the karat. A stud pair carries very little gold, so the diamond is most of what you buy. For another carat or karat, ask on the live chat.
Can I return diamond studs, and how fast do they ship?
Yes, within fourteen calendar days from delivery, the studs unworn and unaltered. The desk clears them for our insured label. The return postage and five percent restocking come off. Custom studs are final. Stock pairs leave in two to five business days.
