FAQs: Diamonds Tennis Necklace – What You Need to Know

What makes this tennis necklace unique?

This necklace combines timeless style with luxurious detail. You’ll find 164 natural diamonds, all hand-set and cut to maximise brilliance. Their F colour and VS clarity ensure sparkle from every angle, while the 40cm length flatters any neckline.

Unlike chunkier designs, this necklace keeps things sleek—perfect for everyday glamour or elevated events.

Can I wear this tennis necklace daily?

Yes! We’ve designed this necklace to offer elegance without sacrificing practicality. The articulated design makes it flexible, so it sits naturally on your neckline. Plus, the secure white gold setting keeps each diamond in place.

We recommend a gentle clean every few weeks and a professional check-up once a year. Book a care appointment whenever you’re ready.

How should I style a 40cm necklace?

A 40cm tennis necklace rests beautifully at the collarbone. You can layer it with a longer chain or pendant, or wear it alone for a refined statement. It pairs perfectly with an open neckline and looks just as good with casual button-downs as it does with a cocktail dress.

Add a pair of diamond studs or a bracelet to complete the look. Browse our earrings for ideas.

Are the diamonds natural and ethically sourced?

Yes. We use only natural diamonds that meet ethical sourcing standards. Each stone in this necklace is responsibly sourced and hand-selected by our gem experts.

With full traceability, we guarantee beauty you can feel good about.

Can I customise the length or design?

Definitely. This model measures 40cm, but we can create a custom version just for you—longer, shorter, or with a different metal colour. We can even increase or reduce the carat weight if you prefer something more minimal or more opulent.

Let’s personalise it together. Book your design consultation.

Is this necklace a good gift for a special occasion?

It’s one of the best. This tennis necklace makes a standout gift for weddings, anniversaries, milestone birthdays, or simply a “just because” moment. With over 9 carats of diamonds and a timeless design, it’s not just a gift—it’s a keepsake.

You can also choose our premium packaging for a luxurious presentation experience.
