A lab grown diamond tennis bracelet is a flexible line bracelet set with a continuous row of matched diamonds — grown in a laboratory rather than mined — that are optically, chemically and physically identical to natural diamonds. Because lab grown stones cost far less to produce, you can wear the same brilliance, carat weight and certified quality for roughly 40–70% less than a comparable natural-diamond bracelet. At Infinite Gems, every bracelet is handcrafted to order in our Hong Kong atelier with D–F colour, VVS–VS clarity diamonds. Because a tennis bracelet is set with many small stones, the individual diamonds do not come with their own certificates — but an optional IGI certificate covering the finished bracelet (its diamond quality and gold content) is available as a paid extra, simply requested upfront.
This guide covers what a tennis bracelet is, how much you should expect to pay, how to choose carat weight, settings and metal, and how to make sure your diamonds are genuinely certified.
What is a tennis bracelet?
A tennis bracelet is a slim, flexible bracelet featuring a single continuous line of diamonds of uniform size and cut, held together by small links. The name dates to a famous 1987 US Open match, when tennis champion Chris Evert paused play to recover her dropped diamond line bracelet — and the style has carried the name ever since.
The defining qualities are symmetry (every stone matched for size, colour and clarity), a secure clasp, and enough articulation to drape comfortably around the wrist. It is one of the few pieces of fine jewellery that works equally well with everyday wear and black tie.
Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are real diamonds. They have the same carbon crystal structure, hardness, sparkle and fire as mined diamonds, and they are graded on the same 4Cs — cut, colour, clarity and carat. The only difference is origin: ours are created in a controlled environment over a few weeks rather than formed underground over millions of years.
For a tennis bracelet, where you are buying many stones at once, this distinction matters enormously to the price. The same row of brilliant, eye-clean diamonds simply costs a great deal less when grown — which is why lab grown is now the default choice for buyers who want maximum carat weight and quality for their budget.
How much does a lab grown diamond tennis bracelet cost?
Price is driven mainly by total carat weight, then by colour, clarity, metal and setting. As a guide, an Infinite Gems lab grown diamond tennis bracelet starts from around USD 1,800 for a 3-carat bracelet, with 5-carat designs and above rising from there. A natural-diamond equivalent would typically cost two to three times as much for the same specification.

A few principles to keep in mind:
- Carat weight is the biggest lever. Doubling the total carat weight roughly doubles the diamond cost, all else equal.
- Loose stones save the most. If you are buying a loose diamond, lab grown can be 70–90% less than natural; for a finished, handcrafted bracelet, expect a 40–70% saving.
- Certification is an optional extra. The small stones in a tennis bracelet are not certified individually; you can add an optional IGI certificate covering the whole bracelet — a modest add-on that documents its diamond quality and gold content.
How many carats should a tennis bracelet be?
There is no single right answer — it depends on the look you want and how you will wear it.
- 2–3 carats total: an elegant, everyday line that sits delicately on the wrist. Ideal as a first tennis bracelet or for stacking.
- 4–7 carats total: the classic, confident look most people picture — clearly visible sparkle without overwhelming the wrist.
- 10 carats and above: a true statement piece, with larger individual stones and significant presence.
If you are unsure, a 3–5 carat bracelet is the most versatile starting point. Because we make every piece to order, you can choose the exact total carat weight that suits you.
Prong vs bezel: which setting is right for you?
The setting determines both the look and the security of your bracelet.
- Four-prong (classic) setting: each diamond is held by four delicate prongs that lift the stone and let light enter from all sides, maximising brilliance. This is the traditional tennis-bracelet look. Explore our classic tennis bracelets.
- Bezel setting: a thin rim of metal surrounds each diamond. It is sleeker, more modern, and exceptionally secure — a great choice for active wear or anyone who wants a contemporary finish. See our bezel bracelets.
Both settings can be made in any of our metals and carat weights; the choice is purely about style and lifestyle.
Choosing your metal
Every Infinite Gems tennis bracelet can be made in 18K White Gold, 18K Yellow Gold, 18K Rose Gold or Platinum. White gold and platinum keep the focus entirely on the diamonds and suit cooler skin tones; yellow and rose gold add warmth and a more vintage character. Platinum is the most durable and hypoallergenic option, which some buyers prefer for a piece worn daily.
How to choose the right length
Tennis bracelets are typically offered from about 15cm to 18cm. The bracelet should sit comfortably against the wrist with just enough movement to rotate, but not so loose that it slides over the hand. If you are between sizes, size up slightly — a tennis bracelet is meant to drape, not grip. Our team can advise on the ideal length for your measurements before we begin crafting.
Certification and quality: what to check
Before buying any diamond tennis bracelet, confirm the following:
- Diamond grade: look for D–F colour and VVS–VS clarity for eye-clean, white, brilliant stones. This is our house standard.
- Certification: the small diamonds in a tennis bracelet are not certified individually. If you would like certification, you can add an optional IGI certificate covering the whole bracelet — documenting the gold content and the quality of our diamonds. Please request it upfront, as it is a paid add-on.
- Matching: in a tennis bracelet, consistency matters — every stone should match its neighbours in size, colour and cut.
- Craftsmanship: check the clasp, the security of each setting, and the flexibility of the line.

Frequently asked questions
How much does a lab grown diamond tennis bracelet cost?
At Infinite Gems, prices start from around USD 1,800 for a 3-carat bracelet and rise with total carat weight, colour, clarity, metal and setting — typically 40–70% less than a comparable natural-diamond bracelet. See our UAE price guide for a full breakdown.
Are lab grown diamond tennis bracelets real diamonds?
Yes. Lab grown diamonds are genuine diamonds with the same chemical, physical and optical properties as mined diamonds, graded on the same 4Cs. The only difference is that they are created in a laboratory.
How many carats should a tennis bracelet be?
Most buyers choose between 3 and 7 carats total. 2–3 carats gives a delicate everyday line, 4–7 carats the classic look, and 10 carats or more a true statement piece.
What is the difference between a prong and a bezel tennis bracelet?
A four-prong setting lifts each diamond for maximum brilliance and gives the classic look; a bezel setting surrounds each stone with a thin metal rim for a sleeker, more secure, modern finish.
Do lab grown diamond tennis bracelets hold their value?
Lab grown diamonds are bought primarily for beauty and value rather than resale. You receive far more certified carat weight for your budget, which is why they have become the practical choice for fine jewellery like tennis bracelets.
Are the diamonds certified?
Not individually. The small diamonds in a tennis bracelet do not come with their own IGI certificate. However, you can add an optional IGI certificate covering the whole bracelet — certifying the gold content and the quality of our diamonds. Please request this upfront, as it is a paid add-on.
How do I care for a diamond tennis bracelet?
Clean it gently with warm water, mild soap and a soft brush, store it separately to avoid scratches, and have the clasp and settings checked periodically. With basic care, a tennis bracelet lasts a lifetime.
