I’ll admit it — I used to think diamonds were out of reach for most of us. They belonged in glossy magazine spreads or on red carpets, not in an ordinary jewellery box. But lately, something’s been changing. It’s not just about trends or technology — it’s about how we think of luxury itself. And at the heart of this quiet revolution? Lab grown diamond tennis necklaces.
If you’ve seen one in person, you’ll know what I mean. They have that unmistakable sparkle — clean, icy, almost liquid in how they catch the light — and yet, there’s a different kind of story behind them. Not one of mining pits and heavy environmental tolls, but of innovation, transparency, and yes, affordability.

Why Everyone’s Talking About Tennis Necklaces Again
Tennis necklaces have a funny way of cycling back into fashion every decade or so. From Chris Evert’s famous bracelet moment in the 1980s (you know, when she stopped mid-match to pick up her lost diamond bracelet — hence the “tennis” name) to the minimal, layered looks on TikTok today, they’ve always symbolised something timeless.
But right now, they’re not just a luxury piece — they’re a lifestyle statement. The modern tennis necklace isn’t locked in a vault; it’s worn with linen shirts, blazers, even gym wear. It’s effortless, genderless, and surprisingly versatile. I’ve seen twenty-somethings pair them with hoodies, and execs wear them with crisp white tees under their suits.
The twist? Many of these new pieces feature lab grown diamonds. Not because they’re cheaper (though they definitely are), but because they align with how people want to feel about what they wear — confident, conscious, and a little bit ahead of the curve.
The Rise of Lab Grown Diamonds
Here’s the thing a lot of people don’t realise: a lab grown diamond is a diamond. Not a fake, not a knock-off, not a cubic zirconia in disguise. Chemically, physically, and visually, it’s identical to one formed deep underground — only it’s created above ground in a controlled environment.
The process fascinates me. Scientists essentially mimic the same pressure and heat that nature uses, compressing carbon into dazzling crystalline form. It’s like speeding up what the Earth does over millions of years — but with precision and purpose.
The result? A diamond that’s just as brilliant, but without the environmental footprint or ethical grey areas tied to traditional mining. It’s not hard to see why younger generations — particularly Millennials and Gen Z — are leaning into it. They want beauty that doesn’t come with baggage.
For anyone curious about how these stones are made or their surprising industrial applications (and yes, diamonds are used for much more than jewellery), you might find this article on man made diamonds genuinely eye-opening. It’s incredible how something once reserved for engagement rings now plays a part in technology and science.
The Appeal of Lab Grown Diamond Tennis Necklaces
So what makes lab grown diamond tennis necklaces such a hot topic right now? Honestly, it’s a mix of design freedom, ethics, and economics.
When jewellers aren’t restricted by the astronomical cost of mined diamonds, they can get creative. You’ll find pieces with larger stones, more intricate settings, even coloured diamond variations — all at prices that would’ve seemed laughably low a decade ago.
A traditional one-carat diamond might set you back tens of thousands. With lab grown stones, you can get a similar quality piece for a fraction of that, without compromising brilliance or cut. It’s democratising luxury in a way that’s refreshing.
And it’s not just about cost. The environmental argument carries real weight. Diamond mining, despite improvements, still disrupts ecosystems and consumes enormous resources. Lab grown production, by comparison, uses far less water and energy — especially when powered by renewable sources.
When you add ethical sourcing, modern technology, and impeccable style into the mix, you get a product that speaks to modern values. That’s the allure of the Lab grown diamond tennis necklaces now catching attention in the luxury market — they offer elegance with integrity.
How They Fit Into Everyday Life
I had the chance to wear one for a week — a delicate 3-carat equivalent, minimalist clasp, yellow gold setting. It wasn’t sponsored, just a personal experiment to see how practical it really was. To my surprise, I didn’t want to take it off.
Unlike statement jewellery that demands a moment, a lab grown diamond tennis necklace quietly elevates everything. It sits comfortably against the skin, catching light in the most natural way. At brunch, it looked chic with a white cotton shirt. In the evening, under soft lighting, it shimmered just enough to feel special.
What’s interesting is how people reacted. No one asked, “Are those real?” — they simply noticed the sparkle. And that, I think, captures the cultural shift happening now. The question of “real” has evolved. Authenticity isn’t about geological origin; it’s about transparency and intention.
The Investment Question
I know what some people are thinking — if it’s lab grown, does it hold value? Fair question. The resale market for lab grown diamonds is still developing, and right now, it doesn’t match the traditional diamond trade in terms of long-term investment.
But maybe that’s not the point anymore. Jewellery has always carried emotional value first. When you buy a piece like a tennis necklace, you’re buying the craftsmanship, the design, the feeling it gives you.
And if you can have all that — plus the peace of mind that it’s ethically sourced — at a lower cost, then it’s arguably a smarter investment in personal happiness, if not pure economics. Besides, the technology behind man made diamonds is advancing rapidly; as awareness grows, their perceived value is rising too.
What To Look For When Buying One
If you’re considering adding a lab grown diamond tennis necklace to your collection, here are a few genuine tips I picked up while researching and chatting with jewellers:
1. Prioritise certification.
Just like mined diamonds, lab grown stones should come with grading certificates from reputable labs like IGI or GIA. These outline the 4Cs — cut, colour, clarity, and carat.
2. Pay attention to metal type.
White gold and platinum tend to highlight the cool brilliance of diamonds, while yellow or rose gold offers a warmer contrast. It’s all about personal preference and skin tone.
3. Don’t overlook craftsmanship.
A tennis necklace should feel fluid, not stiff. The setting should be secure, yet flexible enough to move with your body. The clasp — often ignored — should be sturdy but seamless.
4. Compare brands.
There’s a growing number of Australian jewellers specialising in lab grown diamonds, many of them offering bespoke options. Some even use recycled gold or sustainable packaging, which adds another layer of mindfulness to the purchase.
The Human Side of the Story
What really draws me to this shift, though, isn’t just the science or sustainability — it’s the human sentiment behind it. For decades, diamonds symbolised status, sometimes even excess. Now, they’re being reimagined as a form of conscious self-expression.
I spoke to one Melbourne designer who put it beautifully:
“A diamond should celebrate life, not cost the planet. When people choose lab grown, they’re not rejecting tradition — they’re refining it.”
That line stuck with me. Because that’s what the whole movement feels like — refinement. A re-alignment of beauty and ethics, without losing the emotional resonance that makes jewellery special in the first place.
Where It’s All Heading
If the past few years are anything to go by, lab grown diamonds are here to stay. Global demand has surged, prices are stabilising, and big-name luxury houses are quietly entering the space. What started as an alternative is fast becoming a new standard.
In Australia, the conversation feels especially relevant. We’re a country that values innovation and sustainability — and honestly, we don’t like being taken for a ride when it comes to pricing. Lab grown diamond tennis necklaces hit that sweet spot: modern, responsible, and beautifully made.
I suspect we’ll soon see them become the default option, much like electric cars are becoming for the automotive world. Not because they’re trendy, but because they just make sense.
A Sparkle With Meaning
I’ll finish with this: jewellery has always been about stories. The one you wear on your wrist, around your neck, or tucked under your shirt says something about who you are — and what you stand for.
Choosing a lab grown diamond tennis necklace isn’t just a style choice. It’s a small but powerful declaration that luxury can evolve — that beauty and ethics don’t have to exist on opposite ends of the spectrum.
