Diamond Tennis Bracelet: Lab Grown or Natural? An Honest Guide
Vazgen Martirosov
Quick answer: a diamond tennis bracelet is one continuous line of equal-sized round diamonds, each in its own small setting, linked so the bracelet drapes and moves with your wrist. The big choice today is which diamonds go in it: natural diamonds, formed in the earth, or lab grown diamonds, which are real diamonds grown in a laboratory for much less money. Below: what a tennis bracelet is and where the name comes from, the honest differences between lab grown and natural, and how to choose the gold colour and size.
Picture a Tuesday. A coffee cup, a sleeve pushed back, nobody dressed for anything. The bracelet catches the light every time you reach across the table. That's the quiet job a diamond tennis bracelet does, and it's why so many women end up wearing theirs every day instead of saving it for weddings.
What is a diamond tennis bracelet, and why is it called that?
A tennis bracelet is a flexible bracelet made of one row of matching round diamonds. Each diamond sits in its own setting, and the settings are linked so the bracelet moves with your wrist instead of sitting stiff like a bangle. Jewellers also call it a line bracelet or a rivière.
The name comes from a story every jeweller knows. In 1987, the story goes, tennis player Chris Evert's diamond line bracelet came loose during a match at the US Open, and she asked to pause play until it was found. After that, everyone wanted "the tennis bracelet." There's a less glamorous lesson hidden in the story too: a strong clasp, and a setting check now and then, matter more than most people think.
Lab grown vs natural diamond tennis bracelet: the honest differences
Our Diamond Tennis Bracelet is one design with two diamond choices, which makes this a fair comparison: the same 3.04 carats, the same 14K gold, the same sizes. Only the diamonds change.
Are lab grown diamonds real? Yes. They're diamond: the same carbon crystal, the same hardness, the same fire and sparkle. They are not cubic zirconia and not moissanite, which are different materials that only look similar.
How it looks. The same. On the wrist, nobody can tell lab grown and natural diamonds apart by eye, and a standard diamond tester can't either; it takes laboratory equipment.
Price. The lab grown version costs much less. The natural version costs noticeably more, for the same carat weight.
Value over time. Natural diamonds are rarer and hold their value far better. Lab grown diamonds have low resale value. If you think you might sell the bracelet one day, this is the difference that matters.
The story. Some people want natural diamonds for an heirloom or a once-in-a-lifetime gift, because of where they came from. Others care more about how much sparkle they get for their budget. Both are good reasons, and neither option is automatically "better quality": quality comes from the individual stones and how well they're set, not from where they grew.
Is a lab grown tennis bracelet worth it?
For most people who plan to wear it, yes. A lab grown diamond tennis bracelet is worth it if you want the full 3-carat line on your wrist, you'll actually wear it rather than keep it in a drawer, and you're buying it to keep, not to resell. Choose natural diamonds if it's meant to be passed down, if the origin of the stones matters to you or to the person receiving it, or if holding value is part of the plan.
How much is a diamond tennis bracelet? It depends on the total carat weight, the gold and the stones, so any number you read in a blog goes out of date fast. What stays true: the lab grown version of the same bracelet costs much less than the natural one. On our product pages you'll see the current price for both the moment you choose Natural or Lab-grown.

Yellow gold or white gold? A yellow gold diamond tennis bracelet feels warm and classic, and the white diamonds stand out against the gold. A white gold diamond tennis bracelet is cooler, so metal and diamonds blend into one clean line of light. Stuck? Look at the watch or rings she already wears every day. They usually answer the question for you.
How to find your tennis bracelet size
A tennis bracelet should sit with a little room. Too tight and the links strain; too loose and it slides over your hand. Measure your wrist just above the wrist bone with a soft tape (or a strip of paper and a ruler), then find your wrist in the chart below. Between two sizes? Go up.
| Size | Bracelet length | Fits a wrist of |
|---|---|---|
| XS | 15 cm | 13.5–14 cm |
| S | 16 cm | 14.5–15 cm |
| M | 17 cm | 15.5–16 cm |
| L | 18 cm | 16.5–17 cm |
| XL | 19 cm | 17.5–18 cm |
| XXL | 20 cm | 18.5–19 cm |
Most women wear S or M. Buying it as a surprise? Borrow a bracelet she already wears comfortably, lay it flat, measure it end to end, and pick the size with that bracelet length. Nobody has ever been caught doing that.
Can you wear a diamond tennis bracelet every day?
Yes, with a little sense. Take it off for the gym, gardening, cleaning and heavy lifting, since a hard knock can loosen a setting. Keep chlorine, seawater, perfume and lotion away from it; buildup dulls the sparkle. To clean it, use warm water, a drop of mild dish soap and a soft toothbrush behind the stones, then rinse and dry with a lint-free cloth. Store it flat or in its own pouch. If you wear it daily, have a jeweller check the settings and clasp now and then. Remember the tennis story: a tired clasp is how these bracelets get lost.
Frequently asked questions
Is a lab grown diamond tennis bracelet made of real diamonds?
Yes. Lab grown diamonds are chemically, physically and optically diamond. They are not cubic zirconia or moissanite.
Can anyone tell a lab grown tennis bracelet from a natural one?
Not by eye, and not with a standard diamond tester. Telling them apart takes laboratory equipment.
Does a lab grown tennis bracelet hold its value?
Not well. Lab grown diamonds have low resale value, while natural diamonds hold their value far better. Buy lab grown to wear and enjoy, not to resell.
Which sizes and colours can I choose?
Six sizes, from XS (15 cm) to XXL (20 cm), in 14K yellow gold or 14K white gold, with lab grown or natural diamonds.
Can I exchange it if it's not right?
Yes. Within 7 days of delivery you can exchange it for a different size or gold colour of the same bracelet, as long as it's unworn. We don't offer refunds, and exchange shipping is paid by the customer. If it arrives damaged or faulty, we'll repair or replace it. The full details are in our refund and exchange policy.
A line of light, your choice of diamonds
Back to that Tuesday and the coffee cup. Whichever diamonds you choose, it's the same line of light on your wrist, catching the sun every time you reach for something. Pick your gold, pick your diamonds, and let it become the thing you forget you're wearing until someone asks about it.
