3 Carat Lab Grown Diamond Tennis Bracelet
Three carats is the lightest weight at which a tennis bracelet still reads as a continuous line of diamonds rather than a scattering of small stones. At a 7 inch length the line measures 2.2mm across — fine enough to sit under a shirt cuff and to stack with a watch, which is why it is the weight most people buy first.
Shop QSE 3 carat bracelets run from $2,079 to $2,900 depending on metal and length, every stone IGI certified at E-F color and VS1-VS2 clarity, set in solid 14K or 18K gold with a four-prong setting and a box clasp with a safety latch.
How 3ct wears
At this weight the individual stones are small enough that the eye reads the line rather than the stones. That is the point of a 3 carat bracelet: it is jewelry you forget you are wearing. It clears a shirt cuff, it does not catch on knitwear, and it sits flat under a watch strap.
It is also the weight that stacks. A 3ct line beside a watch or a second bracelet reads as deliberate; heavier weights start to compete.
Who it suits
- A first tennis bracelet. The entry point that still looks like the real thing.
- Daily wear. Light enough for a desk, a keyboard and a coat sleeve.
- Stacking. The only weight in our range that layers comfortably with a watch.
How the weights compare
All four weights are made in the same six lengths and the same four-prong setting. What changes is the width of the line across the wrist, measured here at a 7 inch length.
| Total weight | Width at 7" | Reads as |
|---|---|---|
| 3ct | 2.2mm | A fine line |
| 5ct | 2.9mm | Clearly diamonds, still comfortable |
| 7ct | 3.3mm | A wider, brighter line |
| 10ct | 4.1mm | A substantial band |
Choosing your length
We make six lengths: 6", 6.5", 6.75", 7", 7.5" and 8". Measure your wrist snugly just below the wrist bone and add about half an inch. If you fall between two sizes, choose the larger — a tennis bracelet is a rigid line rather than a draping chain, so a tight one does not soften with wear.
Tennis bracelets cannot be shortened or lengthened after purchase, because each is certified for its exact diamond count and total carat weight. Our bracelet sizing guide has the full size chart.

Common questions
How much is a 3 carat lab grown diamond tennis bracelet?
Shop QSE 3 carat tennis bracelets run from $2,079 to $2,900, depending on the metal and the length. Every stone is IGI certified at E-F color and VS1-VS2 clarity.
How wide is a 3 carat tennis bracelet?
About 2.2mm at a 7 inch length. That is the narrowest line in our range, which is why a 3ct bracelet sits comfortably under a cuff and beside a watch.
Is 3 carats big enough for a tennis bracelet?
Yes, if you want a bracelet you can wear daily. At 3 carats the stones read as a continuous line rather than as individual diamonds. For a line that reads clearly as diamonds across a room, 5 carats is the usual step up.
What lengths does the 3 carat bracelet come in?
Six lengths: 6", 6.5", 6.75", 7", 7.5" and 8". Measure your wrist and add about half an inch.
Can a 3 carat tennis bracelet be worn every day?
Yes. Lab grown diamonds are 10 on the Mohs hardness scale, and the box clasp includes a safety latch. At 2.2mm the line is light enough that most people leave it on.
Can a tennis bracelet be resized?
No. Each bracelet is certified for its exact diamond count and total carat weight, so adding or removing stones would invalidate the certification. If the length is wrong we can exchange it for the correct size.
