Diamonds & carat weight

Lab-Grown Diamonds, sorted by hand for color and size so the line reads evenly all the way around the wrist. Choose your total carat weight in the selector above — more carats means larger stones. See the carat weight guide below for stone sizes.

Prong setting

Each diamond is held in slim prongs of solid 14K gold and left open to light from every side. We make our prong-set bracelets in four-prong, three-prong and two-prong styles — see the prong comparison below. Each setting sits in its own hinged link, hand-set at our bench in Woodside, Queens. As with any prong setting, have it checked once a year to keep every stone tight.

Clasp & security

A box clasp that slides in and clicks shut, locked by a hinged safety latch on each side. Both latches have to be opened before the bracelet can come off, so it stays on your wrist even if the box is knocked.

Sizing

Available in 6″, 6.5″ and 7″ finished length. Measure your wrist just below the wrist bone, add about ¼″ for a close fit or ½″ for a little movement, and choose the closest length. Wrist larger than 6.75″? Message the workshop and we’ll size it to you.

Production & shipping

Made to order in our Woodside, Queens workshop. Production takes 10–15 business days, then your bracelet ships with free priority shipping, fully insured, signature required on delivery.

Product description

2.5 Carat Lab-Grown Diamond Tennis Bracelet, Four-Prong Set in Solid 14K Gold

Eighty-three round Lab-Grown Diamonds, each held in its own four-prong basket, running in one unbroken line of light around the wrist. Two and a half carats total weight of D to F color, VS clarity stones, set by hand in solid 14K white or yellow gold at our Woodside, Queens workshop. The classic tennis bracelet, built to order instead of pulled from a display case.

How much sparkle is a 2.5 carat tennis bracelet?

On the 7-inch bracelet, 2.5 carats total weight is spread across approximately 83 round brilliant Lab-Grown Diamonds, each close to 2mm across. That is the size that reads as a continuous ribbon of light from across the room while staying fine enough to wear next to a watch, stack with a bangle, or slide under a shirt cuff at the office. It is a clear step up from the delicate 1 to 2 carat bracelets most first-time buyers start with, without crossing into the 4 to 5 carat range that turns a tennis bracelet into an evening-only piece.

What diamond quality is used?

Every stone is graded D to F in color and VS clarity or better: colorless, bright white, and eye-clean. Many mass-produced lab-grown tennis bracelets use F-G color and drop into SI clarity to hit a price; across 83 stones, that difference shows up as a slightly warmer, softer line. A D to F, VS row stays crisp and icy from end to end, in white gold and yellow gold alike.

Why a four-prong setting?

Four prongs hold each diamond at its corners and leave the rest of the stone open to light, so every diamond sits square, shows its full face, and the line between stones stays tight. It is the most time-tested way to set a tennis bracelet, and it is the setting any jeweler can inspect and re-tip easily years from now. Every link is hinged, so the bracelet drapes and moves with the wrist instead of sitting stiff.

Is the clasp secure enough to wear every day?

The bracelet closes with a box clasp that presses in until it clicks, backed by a safety latch on each side. The clasp and both latches all have to give way before the bracelet can open. That double-latch build is what lets a tennis bracelet go from the dinner table to the gym bag to the keyboard without a second thought.

Which length should I choose: 6, 6.5, or 7 inches?

Measure the wrist just above the wrist bone with a soft tape or a strip of paper, then add about half an inch so the bracelet moves freely without sliding over the hand. A 5.5-inch wrist wears the 6-inch bracelet, a 6-inch wrist the 6.5-inch, and a 6.5-inch wrist the 7-inch. The 2.5 carat total weight is measured on the 7-inch length; the 6-inch and 6.5-inch bracelets use the same stone size and spacing with proportionally fewer stones, so their total carat weight is slightly lower. Need a longer length? Ask, and it will be built to measure.

White gold or yellow gold?

14K white gold disappears around the stones and lets the bracelet read as an almost solid line of diamond, cool and modern. 14K yellow gold frames each Lab-Grown Diamond in warm metal for a richer, gold-forward look that pairs naturally with yellow gold watches and chains. Both are solid 14K gold through every link, never plated and never hollow.

Are Lab-Grown Diamonds real diamonds?

Yes. Lab-Grown Diamonds are real diamonds: the same carbon crystal, the same hardness, and the same fire and brilliance as mined diamonds, grown under controlled conditions instead of dug from the ground. What changes is the price. A 2.5 carat tennis bracelet in solid 14K gold comes in well under what traditional jewelry retail charges for a comparable mined-diamond line. Stones of this size are not individually graded by a lab, so the bracelet arrives without an IGI report.

How is it made, and how long does it take?

Every bracelet is made to order in Queens, NYC by Dimitrios Koukoulis. There is no warehouse and no mass production; the bracelet is assembled link by link, every Lab-Grown Diamond is set and checked under magnification, and the clasp is fitted and tested before the final polish. Production takes 10 to 15 business days, and the finished bracelet ships fully insured in a Black Pearl of Queens pouch. Standard lengths are covered by our 14-day return policy.

Who is a 2.5 carat tennis bracelet for?

The milestone self-purchase: the promotion, the big birthday, the year that deserved marking with something permanent. The anniversary or push present that says more than flowers ever could. The bride who wants one serious piece of diamond jewelry she will keep wearing long after the wedding day. It is the bracelet bought once and worn for decades.

How it’s built

Anatomy of our prong-set tennis bracelet

Matched diamonds

Every stone is sorted by hand for color and size, so the line reads as one even ribbon of light.

Hand-set prongs

Slim prongs of solid 14K gold hold each diamond open to light from every side — in four-, three- or two-prong styles.

Hinged links

Every setting sits in its own hinged link, so the bracelet drapes and moves like fabric on the wrist.

Double-latch clasp

A box clasp locked by a safety latch on each side. Both must open before the bracelet can come off.

More prong styles: all prong-set tennis bracelets. Wearing it every day? See our bezel tennis bracelets for a snag-free setting.

Prong-set, three ways

4-prong vs 3-prong vs 2-prong tennis bracelets

Every prong-set bracelet holds its diamonds in solid 14K gold — the difference is how many prongs grip each stone. Fewer prongs means less metal and more diamond on show; more prongs means a firmer hold.

Four-prong

The classic tennis bracelet. Four prongs grip each diamond from every side for the most secure hold, framing each stone in a neat square of gold.

Best for: everyday wear and the traditional look.

Three-prong

Three prongs let the stones sit closer together and look rounder, so the line reads as more continuous — a balance of security and sparkle.

Best for: a fuller line of diamond with a softer, rounder look.

Two-prong

The least metal of any setting. Two slim prongs hold each diamond so the stones nearly touch, creating an almost unbroken ribbon of diamond.

Best for: maximum diamond and the most minimal metal.

As with any prong setting, have your bracelet checked by a jeweler about once a year to keep every stone tight.

One bracelet · your carat weight

2, 3 or 5 carat tennis bracelet? Choose your carat weight

Every tennis bracelet we make is offered in multiple total carat weights, and you pick yours when you order. Total carat weight is the combined weight of every diamond on the bracelet. On a fixed length, more carats means larger stones and fewer of them. Figures below are approximate for a 7″ bracelet with round diamonds.

Total carat weightApprox. stone sizeApprox. stonesHow it wears
1 ct1.7–1.8 mm55–60A fine, delicate line. Built for stacking and wearing every day.
2 ct2.2–2.4 mm45–50Sparkle you see from across the room, still light on the wrist.
3 ct2.7–2.9 mm40–45The statement size that still sits flat enough to wear daily.
5 ct3.3–3.5 mm35–38Bold, substantial, impossible to miss.

The carat weights available on each bracelet are listed in the selector on its page. Want a weight that isn’t listed? We’ll build it.

Tennis bracelet questions

Is a prong or bezel tennis bracelet better?

It depends on how you'll wear it. Prong settings leave more of each diamond open to light, so they give the most sparkle and the classic tennis bracelet look. Bezel settings wrap each diamond in gold, so they're smoother, won't snag on clothing and protect the edge of every stone, which makes them ideal for everyday wear. We build both, in the same carat weights.

What is the difference between 4-prong, 3-prong and 2-prong tennis bracelets?

It comes down to how many prongs hold each diamond. Four-prong is the classic and most secure, framing each stone in gold. Three-prong lets the stones sit closer and look rounder for a more continuous line. Two-prong uses the least metal, so the diamonds nearly touch and the bracelet reads as an almost unbroken ribbon of diamond. We make all three in solid 14K gold.

What is a bezel tennis bracelet?

A bezel tennis bracelet is a line of diamonds where each stone is wrapped in a full rim of metal instead of being held by prongs. Ours are bezel-set in solid 14K gold, which gives a smooth edge that won't snag and protects the edge of every diamond.

What is a prong-set tennis bracelet?

A prong-set tennis bracelet holds each diamond with small metal prongs. Because the prongs cover very little of the stone, more light enters each diamond, giving the brightest sparkle. We make them in four-prong, three-prong and two-prong styles. As with any prong setting, we recommend having the prongs checked by a jeweler about once a year.

How many carats should a tennis bracelet be?

It depends on the look you want. Around 1 carat total is a fine, delicate line for stacking. 2 to 3 carats is the balanced choice with sparkle you notice from across the room. 5 carats is a bold statement piece. Each of our bracelets is offered in multiple carat weights, so you choose yours when you order.

What is a tennis bracelet?

A tennis bracelet is a flexible bracelet made of a single continuous line of matched diamonds, each set in its own hinged link. The name dates to 1978, when Chris Evert lost her diamond line bracelet mid-match at the US Open and play stopped while she found it.

Are Lab-Grown Diamond tennis bracelets real diamonds?

Yes. Lab-Grown Diamonds are physically, chemically and optically the same as mined diamonds. The difference is origin: they are grown in a controlled environment rather than mined, which makes a full line of matched stones far more attainable.

How secure is the clasp?

Our tennis bracelets close with a box clasp locked by a hinged safety latch on each side. Both latches have to be opened before the bracelet can come off, so it stays on your wrist even if the box clasp is knocked.

What length tennis bracelet should I get?

Measure your wrist just below the wrist bone, then add about a quarter inch for a close fit or half an inch for a little movement, and choose the closest length. We offer 6, 6.5 and 7 inches. A tennis bracelet should sit close to the wrist rather than hang loose. If your wrist is larger than about 6.75 inches, contact the workshop and we will size it to you.

Can a tennis bracelet be resized?

Yes. Because a tennis bracelet is built from individual links, links can be added or removed to change the length. Contact the workshop and we will walk you through it.

How long does it take to make a tennis bracelet?

Every tennis bracelet is made to order and hand-set in our Woodside, Queens workshop. Production takes 10 to 15 business days, then your bracelet ships free and fully insured.

Can I design a custom tennis bracelet?

Yes. We can build to a specific setting, carat weight, stone shape, metal or length. Start on our custom design page or call or text 929-806-1502.
