Lab Grown Diamond Tennis Necklaces
Shop QSE lab grown diamond tennis necklaces start at $3,465 for 5 carats in solid 14K gold, and run to $15,750 at 25 carats. Every stone is IGI certified at E-F color and VS1-VS2 clarity, and every weight is offered in both 14K white and 14K yellow gold at the same price.
The decision in front of you is really two decisions: how much carat weight, and how long a chain. Weight sets the price and how far the light carries across a room. Length sets where the diamonds sit against your neck and which necklines they work under.
What a tennis necklace is
A tennis necklace is a continuous line of diamonds, each stone individually set in its own four-prong or bezel setting, running the full circumference of the chain. There is no pendant and no front-and-center stone. The design is the line itself, which is why the carat weight is quoted as a total across the whole piece rather than per stone.
The construction is the same idea as a tennis bracelet, extended. If you have read our 5 carat tennis bracelet guide, the settings and the clasp will be familiar; the difference is the length the weight has to cover.
How much does a lab grown diamond tennis necklace cost?
Prices below are the current Shop QSE prices in solid 14K gold, white or yellow, with every stone IGI certified at E-F color and VS1-VS2 clarity. The 20 inch length carries a premium because it holds more diamonds than the shorter chains at the same carat weight per inch.
| Total carat weight | 16 or 18 inch | 20 inch | Reads as |
|---|---|---|---|
| 5 carat | $3,465 | $3,899 | A clear line of light at conversational distance |
| 7 carat | $4,839 | $4,999 | Visible across a dinner table |
| 10 carat | $5,979 | $6,199 | The weight most people picture as a tennis necklace |
| 20 carat | $11,800 | $12,800 | Unmistakable under any light |
| 25 carat | $14,750 | $15,750 | A formal, red-carpet scale piece |
Both metals cost the same at every weight, so the choice between white and yellow gold is purely about which you wear. Our post on choosing between white, yellow and rose gold covers how each sits against different skin tones.
Which length should you choose?
Shop QSE offers 15, 16, 18 and 20 inch tennis necklaces. The 16, 18 and 20 inch lengths are stocked across every carat weight and both metals; 15 inch stock is limited to a few combinations at any given time.
| Length | Where it sits | Works with |
|---|---|---|
| 15 inch | Close around the base of the neck | Open and off-shoulder necklines; a choker-style fit |
| 16 inch | At the base of the neck, just above the collarbone | Crew necks, high necklines, layering above a longer chain |
| 18 inch | At or just below the collarbone | The most versatile length; works over almost anything |
| 20 inch | Below the collarbone, toward the top of the chest | Deeper V-necks and scoop necks; a longer line on a taller frame |
If you are buying as a gift and do not know a preference, 18 inch is the length that needs the least luck. It falls at or just below the collarbone on most adults and sits correctly under both an open collar and a crew neck.
A necklace or a bracelet at the same carat weight?
At 5 carats, a Shop QSE tennis bracelet starts at $2,339 and the tennis necklace starts at $3,465. The diamonds are the same specification in both. The difference in price is construction: the same total weight spread over a 16 inch chain rather than a 7 inch bracelet needs considerably more individual settings and more labor, and the finished line reads as finer, smaller stones.
That cuts both ways, and it is the honest disadvantage of buying weight as a necklace. A carat spent on a necklace buys less apparent stone size than the same carat spent on a bracelet, and far less than on a pair of studs, where the whole weight sits in two stones. If what you want is the largest visible diamond for the money, a necklace is the wrong piece. If what you want is a continuous line of light that follows the neckline, nothing else does it.
The second honest point applies to every lab grown diamond, necklace or not: resale value is markedly lower than for a mined equivalent. Buy it to wear, not as an investment.

Common questions
How much is a lab grown diamond tennis necklace?
Shop QSE lab grown diamond tennis necklaces start at $3,465 for 5 carats in solid 14K gold and run to $15,750 at 25 carats, with every stone IGI certified at E-F color and VS1-VS2 clarity.
What carat weights do tennis necklaces come in?
Shop QSE offers 5, 7, 10, 20 and 25 total carat weights. The 10 carat weight at $5,979 is the one most people picture when they think of a tennis necklace.
What length tennis necklace should I buy?
Eighteen inch is the most versatile and the safest choice as a gift, because it falls at or just below the collarbone on most adults and works under both an open collar and a crew neck. Sixteen inch sits higher, at the base of the neck, and 20 inch sits toward the top of the chest.
Is a tennis necklace available in yellow gold?
Yes. Every carat weight is offered in both 14K white gold and 14K yellow gold at the same price, so the metal choice costs nothing either way.
How much does a 10 carat lab grown diamond tennis necklace cost?
A 10 carat lab grown diamond tennis necklace is $5,979 in 14K white or yellow gold at 16 or 18 inches, and $6,199 at 20 inches.
Should I buy a tennis necklace or a tennis bracelet?
At the same 5 carat weight the bracelet starts at $2,339 and the necklace at $3,465, because the necklace spreads the weight over a longer line and needs more individual settings. The bracelet gives you larger apparent stones for the money; the necklace gives you a continuous line of light along the neckline.
Are lab grown diamond tennis necklaces real diamonds?
Yes. They are pure crystallized carbon with the same atomic structure, the same hardness of 10 on the Mohs scale and the same optical properties as mined diamonds, and they are graded on the same scales by the same laboratories.
How do I clean a diamond tennis necklace?
Warm water, a drop of dish soap and a soft toothbrush along the underside of each setting, then rinse and dry with a lint-free cloth. The underside is where skin oil collects and dulls the stones.
