I’ll be honest — I used to think diamonds were all the same. You know, the glittering little stones that sit behind glass displays in boutique jewellery stores, each one with a story of romance and rarity. But then I learned about lab created diamond tennis necklaces, and everything I thought I knew about luxury jewellery got a quiet little shake-up.
I’m not a gemmologist, but I do write about lifestyle trends for a living — and this one? It’s impossible to ignore. Australia’s jewellery scene has always had a flair for mixing timeless style with modern values, and right now, lab created diamonds are the talk of both Bondi brunches and Collins Street boardrooms.
So let’s dive into it: what’s really behind this sparkling shift, and why are lab created diamond tennis necklaces suddenly the statement piece every modern jewellery lover wants in their collection?
A Quick Flashback: The Tennis Necklace’s Surprising Origin
Before we get to the “lab” part, it’s worth remembering how the tennis necklace got its name. It wasn’t born in a Paris atelier or launched by a celebrity stylist — it actually started on the tennis court.
Back in the 1980s, American tennis champion Chris Evert famously lost her diamond bracelet mid-match at the U.S. Open and asked to pause the game until it was found. The press dubbed it her “tennis bracelet,” and from that moment, the jewellery world had a new icon.
Fast-forward a few decades, and that same minimalist line of diamonds — now in necklace form — has become a favourite among red-carpet stylists and everyday fashion enthusiasts alike. It’s simple, sleek, and utterly wearable. The kind of piece that looks just as good with a linen shirt as it does with an evening gown.
So What Exactly Are Lab Created Diamonds?
Here’s where things get really interesting.
Lab created diamonds (sometimes called “lab grown” or “man-made” diamonds) aren’t fake. They’re not cubic zirconia or crystal. They’re chemically, physically, and optically identical to mined diamonds — the only difference is how they’re formed.
Instead of being pulled from deep within the earth after millions of years underground, these diamonds are grown in high-tech labs using advanced carbon replication technology. It’s a bit like mimicking nature’s recipe, only faster and far more ethical.
If you want to go down the rabbit hole, there’s a fascinating breakdown here about lab created diamonds, including how they’ve become the go-to choice for eco-conscious couples and style lovers who value transparency as much as beauty.
Why They’re Making Waves in Australia
Let’s face it: Australians care about where things come from. From locally roasted coffee to ethical fashion labels, we’ve got a keen eye for sustainability — and that mindset is finally reaching the jewellery box.
For years, the diamond industry has been shadowed by concerns about environmental damage and the murky ethics of mining. Many buyers started asking the uncomfortable question: “Where did my diamond really come from?”
Lab created diamonds answer that question with confidence. There’s no mining, no conflict zones, no damage to ecosystems. They require significantly less water and energy, and they’re traceable from start to finish.
Honestly, it’s a relief — to know that something so beautiful doesn’t come with a hidden cost.
And beyond ethics, there’s a practical reason too: price. A lab created diamond can cost up to 60% less than its mined equivalent. That means more sparkle for your dollar — or, if you’re like most Australians, more reason to finally treat yourself to a necklace that doesn’t just sit in the safe for special occasions.
The Tennis Necklace Revival
Now, let’s talk style.
The tennis necklace has had quite the comeback lately, thanks to the minimalist trends dominating fashion circles. You’ve probably seen celebrities layering delicate diamond lines with chunky gold chains, or pairing them with crisp white shirts for that effortless “quiet luxury” vibe.
What’s changed, though, is accessibility. Where a diamond tennis necklace once felt reserved for A-listers or major anniversaries, lab created diamond tennis necklaces have made that timeless look attainable for more people.
Brands like Novita Diamonds are leading the charge, offering customisable options where you can choose everything — from the carat weight and metal finish to the exact diamond cut. It’s no longer just about buying jewellery; it’s about creating something uniquely yours.
I spoke with a Sydney jeweller recently who said almost half her customers now specifically ask for lab created options. “People want to wear something that reflects their values,” she told me. “It’s not just about the sparkle — it’s about the story behind it.”
Style Meets Substance
If you’ve ever worn a tennis necklace, you’ll know it’s not just an accessory — it’s a statement. It sits lightly on the collarbone, catching the light with every turn of your head. There’s something quietly confident about it.
But when that same necklace is made from lab created diamonds, it adds another layer of meaning. You’re not only choosing elegance; you’re supporting innovation, sustainability, and a more transparent jewellery industry.
It’s a small thing, but it feels good — knowing your style choices align with your values. And that’s becoming a big part of the modern luxury conversation.
Are Lab Created Diamonds “Real”? (The Short Answer: Absolutely.)
This question comes up all the time. And I get it — “lab created” sounds synthetic, maybe even artificial. But here’s the truth: these diamonds are real. The same sparkle, same durability, same hardness. The only thing missing is the geological time stamp.
Even gemmologists often need specialised equipment to tell them apart from mined stones. And most major jewellery certification bodies — like the GIA (Gemological Institute of America) — now grade lab created diamonds the same way they do mined ones, using the familiar 4Cs: cut, colour, clarity, and carat.
So yes, they’re real. Real diamonds, real beauty, real choice.
Investing in Lab Created Jewellery
Now, let’s be realistic: lab created diamonds don’t have the same resale market as mined diamonds just yet. They’re still relatively new, and the industry’s evolving.
But here’s something to consider — most people don’t buy jewellery as an investment. They buy it because it means something. It’s to celebrate a milestone, a personal win, or just a little self-love.
And when you think about it that way, lab created diamonds make even more sense. You can own a stunning, high-quality piece without overpaying for rarity or mining costs. Plus, you’re part of a movement shaping the future of fine jewellery — a future that’s transparent, inclusive, and planet-friendly.
Caring for Your Tennis Necklace
Since we’re talking practicality, let’s not skip the care bit.
Lab created diamonds are just as tough as mined ones, so they’ll stand up to daily wear. But like any fine jewellery, they appreciate a little TLC.
Here are a few quick tips:
- Store it flat: Tennis necklaces are delicate by design — laying them flat helps avoid kinks or stretching.
- Clean gently: Warm water, mild soap, and a soft brush are all you need to keep that sparkle alive.
- Avoid harsh chemicals: Perfume, hairspray, and chlorine are not your diamond’s friends.
Simple habits, but they make a world of difference if you want your necklace to shine like new for decades.
The Emotional Sparkle
Here’s the thing I love most about lab created jewellery — it redefines what luxury means.
Luxury used to be about exclusivity, about owning something others couldn’t. But now, it’s about responsibility. It’s about choosing pieces that reflect who you are and what you care about.
There’s a quiet kind of pride in wearing something that’s both exquisite and ethical. It’s the same feeling you get when you support a local artisan, or buy something handmade that tells a story.
And when that story happens to sparkle under the sunlight? Even better.
The Future of Diamonds
We’re living in a fascinating moment for jewellery. The technology behind lab created diamonds is evolving fast, the designs are becoming more adventurous, and public perception is changing by the day.
What used to be seen as a “budget” alternative is now seen as the smart choice — elegant, innovative, and conscious.
And tennis necklaces? They’re right at the centre of that shift. A symbol of enduring style, reimagined for the next generation.
If you ask me, that’s the kind of sparkle worth investing in.
Final Thought
So, whether you’re eyeing your first diamond necklace or adding to an existing collection, don’t overlook what lab created diamonds bring to the table. They’re not just a trend — they’re the future of fine jewellery, blending science and artistry in a way that feels deeply modern and beautifully human.
And if you ever get the chance to try on a lab created diamond tennis necklace, do it. Watch how the light dances across every facet. Feel how effortlessly it elevates your look. Then think about what it represents — beauty without compromise.
