A tennis necklace is one of those rare pieces that can instantly elevate an outfit while remaining timeless enough to wear every day. But a beautiful tennis necklace is about more than sparkle — stone quality, size, setting, comfort and how well the necklace sits on your neck all matter.
Here are the key things to look for before choosing yours.
1. Choose the Right Stone
Traditional tennis necklaces are known for diamonds, but today there are beautiful alternatives that can deliver exceptional brilliance at a more accessible price.
Lab-Grown Diamonds offer the same crystal structure and optical properties as mined diamonds.
Moissanite is loved for its exceptional brilliance and fire, making it especially striking in a continuous tennis setting.
Premium Diamond Simulants offer beautiful diamond-like sparkle and an elegant look at a much more accessible price point.
The most important thing is to choose a reputable jeweller that clearly tells you exactly which stone you are buying.
2. Choose the Right Stone Size
Even a 1mm difference can dramatically change how a tennis necklace looks.
| Stone Size | Look | Best For |
|---|---|---|
| 2–2.5mm | Delicate & refined | Everyday wear |
| 3mm | Classic & noticeable | Day-to-evening |
| 4mm | Bold & luxurious | Statement styling |
| 5mm+ | Maximum sparkle | Special occasions |
For a first tennis necklace, 2.5–3mm is an especially versatile choice — noticeable enough to sparkle beautifully while remaining easy to wear.
3. Look at the Setting & Craftsmanship
A well-made tennis necklace should create a smooth, continuous line of sparkle.
Look for evenly matched stones, consistent spacing and secure settings. The necklace should also remain flexible enough to follow the natural curve of your neckline rather than feeling stiff.
Good craftsmanship allows the stones to take centre stage while keeping the necklace comfortable and secure.
4. Choose the Right Length
Length can completely change the look.
14 inches — chic and close-fitting
16 inches — classic and versatile
18 inches — relaxed and elegant
If you want one necklace that works with everything from dresses to everyday tops, 16 inches is often the easiest length to style.
5. Check the Clasp
A tennis necklace contains many individually set stones, so a secure clasp matters.
Look for a clasp that closes firmly, feels appropriate for the weight of the necklace and is easy to put on and remove.
A beautiful necklace should feel as effortless to wear as it looks.
6. Most Importantly: Make Sure It Doesn't Flip
This is one of the most overlooked details when buying a tennis necklace.
A poorly balanced necklace can flip or roll as you move, turning the stones towards your skin instead of keeping them facing outward.
And no matter how brilliant the stones are, they can't sparkle if they're facing the wrong way.
The setting, flexibility, weight distribution and construction of a tennis necklace all influence how well it sits on the neckline.
At Sissi Jewellery, our tennis necklaces are carefully tested and specially designed to minimise flipping, helping the stones remain beautifully positioned as you move. The flexible construction also makes them comfortable and effortless to wear.
We select high-brilliance Moissanite and Premium Diamond Simulants for exceptional sparkle and visual impact — creating the luxurious look and brilliance people love in diamond jewellery, without the traditional diamond price.
Because a tennis necklace shouldn't just sparkle beautifully in the box — it should sparkle beautifully on you.
Find Your Perfect Tennis Necklace
When choosing a tennis necklace, don't look at carat weight or price alone. Consider the stone, size, setting, length, clasp, comfort and — importantly — how well it stays facing forward when worn.
The right tennis necklace should feel beautiful, comfortable and effortless enough to reach for again and again.
At Sissi Jewellery, we believe modern luxury should be made to be worn.
Crafted to be worn. Shine with confidence.
