If you’ve walked past a jeweller recently, scrolled through Instagram, or even overheard a chat at a café, you’ve probably noticed that lab grown diamonds have slipped out of the “niche curiosity” corner and straight into the spotlight. And honestly, it makes sense. They’re stunning, accessible, conflict-free, and—this surprised me when I first looked into it—chemically identical to mined diamonds.

Still, while the hype is real, the story behind this shift is even more fascinating. So, let’s talk about why lab grown diamond necklaces are suddenly everywhere, why jewellers are giving them pride of place in their displays, and why more Australians are choosing them not just for major milestones but for everyday wear.

Why Lab Grown Diamond Necklaces Feel So… Modern

There’s something incredibly contemporary about choosing a lab grown diamond. It’s not just the science (though the technology is wild). It’s the idea that luxury can evolve. We’re moving past the old mentality of “real” vs “artificial” and into a space where ethical and sustainable choices feel aspirational, not like a compromise.

To be clear: lab grown diamonds are real diamonds. The same sparkle. The same hardness. The same optical properties. If you handed one to a gemmologist without context, they’d need specialised equipment to tell the difference.

What is different is the story. And in fashion, jewellery, and pretty much every lifestyle sector, story matters just as much as the product.

Lab grown diamond necklaces carry this modern narrative of conscious luxury—something that really resonates with people right now. Especially younger buyers. Especially Australians, who tend to appreciate things that are both practical and principled.

A Quick Tour Behind the Scenes: How They’re Made

I’m not a scientist, but I remember seeing a demonstration a couple of years ago that felt like watching someone bottle lightning. There are two main approaches:

1. HPHT (High Pressure, High Temperature)

This method imitates how diamonds naturally form underground—only in a controlled lab setting, without waiting a few million years.

2. CVD (Chemical Vapour Deposition)

This one’s almost poetic: a tiny diamond “seed” sits in a chamber filled with carbon-rich gas. Over time, the carbon layers build up, atom by atom, growing the diamond like a crystal snowflake.

Both techniques produce gorgeous stones that can then be cut into the shapes we all know—round brilliant, emerald, pear, oval, and so on.

What I loved learning is that every lab diamond has its own quirks. People sometimes assume they’re all clones, but no—nature might not be involved, yet individuality still is.

The Necklace Revival: Why This Style Is Dominating Right Now

We’ve seen an explosion in necklaces over the last couple of years. Part of it is TikTok (which can take a simple 0.5-carat solitaire pendant and make it viral in a day), and part of it is the shift toward Zoom-friendly outfits—clean necklines, subtle jewellery, “effortlessly put together from the shoulders up.”

Lab grown diamond necklaces fit beautifully into this landscape. A few reasons:

1. They’re more affordable without looking “budget.”

Let’s be honest: necklaces sit front and centre. Jewellery lovers want something noticeable without taking out a second mortgage. Lab grown diamonds offer exactly that—bigger stones, higher clarity, better colour options, and still within reach.

2. They’re timeless, not trend-chasing.

Unlike chunky jewellery phases or fleeting microtrends, a simple diamond pendant or tennis necklace never really goes out of style.

3. They’re easy to gift.

I’ve talked to countless jewellers who say necklaces are their “safe pick.” You don’t need to know someone’s ring size or worry whether they prefer hoops or studs. A necklace just works.

4. Sustainability is starting to matter in everyday purchasing.

Even people who aren’t overtly “eco-focused” appreciate the idea of lower environmental impact.

The Ethics Question: Why People Are Thinking Twice About Mined Stones

I’ll tread lightly here because everyone’s values differ. But the conversation around diamond mining is well-known: environmental disruption, labour concerns, and occasionally some murky supply chains.

Lab grown diamonds offer an alternative that feels transparent and reassuring. You know exactly how the stone came to be. And while no industry is entirely impact-free, the footprint is dramatically smaller.

When I interviewed a Melbourne jeweller earlier this year, she put it nicely:
“People want jewellery that reflects who they are now—not who the world was 50 years ago.”

That sentiment keeps echoing in my mind.

Design Trends in Lab Grown Diamond Necklaces

Here’s where things get fun. Because lab grown diamonds are more cost-friendly, designers have more freedom. They’re experimenting. They’re taking risks. And buyers are saying, “Sure, why not? Let’s try a bold pear-cut halo necklace.”

Some of the standout trends:

• The Classic Solitaire Pendant

A favourite for minimalists and everyday wearers. It’s quietly luxurious.

• Cluster Designs

Little constellations of diamonds arranged in organic shapes—really popular among younger shoppers.

• Bezel Settings

This one’s a bit vintage-inspired and very chic. Looks great layered.

• Oval and Pear Cuts

These have made a huge comeback, partly because they elongate the neckline and feel effortlessly elegant.

• Lab Grown Diamond Tennis Necklaces

Okay, these are stunning. And yes, still a splurge—but noticeably more accessible in the lab grown world.

What’s struck me most is how wearable they all are. They’re not locked behind glass cabinets anymore. People are buying them for daily outfits, birthdays, office wear, dinner dates—you name it.

Are Lab Grown Diamonds Good for Gifting?

I get this question a lot. And the answer is, absolutely—if the person you’re gifting to values beauty, ethics, or simply the idea of something modern and thoughtful.

One interesting read I came across recently highlights the emotional side of giving jewellery made with lab grown stones. If you’re into that kind of heart-led approach, you might enjoy this article on lab grown diamonds. It digs into the sentiment behind meaningful gifts, not just the sparkle factor.

Do Lab Grown Diamond Necklaces Hold Their Value?

This is where things often get… a bit misunderstood.

Traditional mined diamonds have a long history and a long-standing resale market. Lab grown diamonds, being newer, don’t have quite the same established second-hand ecosystem yet.

That said, most people aren’t buying necklaces because they plan to flog them at auction in 10 years. Necklaces are purchased for beauty, style, and personal significance. And lab grown diamonds deliver those things in spades.

In a funny way, the lower cost makes them feel more wearable. You won’t feel nervous putting one on before heading to brunch or taking it on holiday.

Why Australians Are Embracing This Trend

Every region has its own jewellery preferences, but Australia has always been a bit ahead when it comes to embracing ethical, practical, and design-forward ideas.

A few reasons Aussies in particular are leaning into lab grown diamond necklaces:

• We appreciate good craftsmanship without the unnecessary markup.
• Sustainability actually matters here—people think about where things come from.
• The casual-luxe aesthetic fits perfectly: simple dresses, breezy linen shirts, a subtle diamond pendant catching the light.
• We’re not as hung up on tradition for tradition’s sake.

It’s refreshing, honestly.

A Few Tips If You’re Thinking About Buying One

Just in case you’re leaning in this direction, here are some simple pointers from jewellers I’ve spoken to:

1. Prioritise cut over carat.

A brilliantly cut diamond—lab grown or mined—will always look more impressive than a bigger but poorly cut stone.

2. Don’t skip certification.

Reputable jewellers will provide grading reports from recognised labs.

3. Consider your lifestyle.

If you’re active or tend to catch necklaces on clothing (we’ve all done it), a bezel setting might be safer than a prong setting.

4. Try it on if you can.

Necklace drop lengths can completely change the vibe. Some sit beautifully on the collarbone; others look better a little lower.

The Real Reason Lab Grown Diamond Necklaces Are Taking Off

If I had to pin it on one thing, it’s this:
People want to feel good about what they’re wearing.

Not just look good — feel good.

A lab grown diamond necklace isn’t just a piece of jewellery. It’s a little symbol of progress. Of choice. Of modern values woven into something timeless.

And there’s something quite special about that.

A Final Thought

Sometimes an industry shifts slowly. Sometimes it shifts with a quiet, steady confidence — and that’s exactly what’s happening with lab grown diamonds.

We’re watching a new chapter of jewellery unfold. Not replacing tradition, but expanding it. Making space for beauty that aligns with who we are today: thoughtful, curious, environmentally aware, and open to innovation.

If you’ve ever loved the sparkle of a diamond but hesitated for one reason or another, lab grown diamond necklaces might be that unexpected solution — the one that feels right on every level.
