As a jewellery writer based in Melbourne, I’ve spent a good chunk of my career darting between workshops, fashion events, and tiny, tucked-away studios where jewellers still hand-polish pendants under warm yellow lamps. And lately, there’s one topic that seems to come up in nearly every conversation — man made diamonds pendants.
A few years ago, most people barely knew what lab-created stones were. These days, though, they’re everywhere: on red carpets, in engagement announcements on Instagram, even in the display windows of the big-name jewellers along Collins Street.
And honestly? I’m not surprised. There’s something quietly revolutionary about the way man made diamonds have shaken up the industry — not with loud statements or aggressive marketing, but with a simple promise: the beauty and brilliance of a mined diamond, minus the environmental and ethical shadows that usually hang over the story.
This article isn’t a sales pitch. It’s more of a guide, a walk-through of what’s happening in the world of diamond jewellery right now, especially for anyone who’s thinking about buying a pendant that means something — whether that’s a milestone piece, a daily necklace, or a gift with a bit of soul behind it.
Why Man Made Diamond Pendants Have Become the New Favourite
The first time I held a man made diamond pendant under the jeweller’s light, I honestly couldn’t tell the difference. And I’m not embarrassed to admit that — even seasoned gemologists need specialised tools to distinguish lab-created diamonds from mined ones. They look the same, sparkle the same, and grade the same on the exact scales the industry has used for decades.
But the reason they’ve exploded in popularity goes beyond aesthetics.
There’s a cultural shift happening. People want beauty that aligns with their values. They want transparency. And they want to know that the jewellery they’re wearing hasn’t come at a human or environmental cost.
When you pair that mindset with the fact that man made diamonds can cost significantly less — sometimes 30–70% less — it’s easy to see why pendants have become a popular starting point. They’re personal, they’re versatile, and they don’t scream for attention. A pendant is worn close to the heart, literally and symbolically.
I’ve spoken with shoppers who buy them because they feel good about the sustainability element. Others just love the idea of getting a larger stone for the same budget. Some are simply drawn to the clean, minimalist designs that jewellers have started creating especially for lab-grown stones.
Whatever the reason, it’s clear the trend isn’t fading.
A Quick Look at How Man Made Diamonds Are Created
You might not know this, but most lab-grown diamonds are formed using one of two methods: HPHT (High Pressure High Temperature) or CVD (Chemical Vapour Deposition).
HPHT mimics the natural diamond-forming conditions within the earth, while CVD grows the diamond from a carbon-rich gas. Neither method is particularly glamorous to watch — it’s more “sci-tech lab at midnight” than “sparkling jewellery showroom.”
But the result? A real diamond. Not an imitation, not a simulant — a diamond with the same carbon structure as the one inside your grandmother’s heirloom ring.
When people first hear the term “man made,” they often imagine something artificial, like cubic zirconia. But a diamond grown in a lab isn’t trying to imitate anything. It is the thing. That’s one misconception I wish the industry had cleared up earlier, because it would have saved a lot of consumers years of confusion.
What Makes Man Made Diamond Pendants Stand Out
Pendants are one of the most forgiving and expressive jewellery forms. Rings need to hold up to daily wear and tear. Earrings need to balance and match. Bracelets need to sit just right. But a pendant? You can get creative.
I’ve seen everything from delicate solitaires on a fine 18ct gold chain to bold geometric pendants with diamond clusters that look like tiny constellations.
There’s something deeply personal about putting a diamond at the centre of your neckline. People don’t always talk about it, but the way a pendant moves with you — catching light when you turn your head or leaning softly against your shirt — makes it feel alive.
Man made diamonds work beautifully in pendants because:
1. You get more room for creativity
Designers don’t have to restrict themselves to tiny stones to keep things affordable. They can play with shape, weight, negative space, or multiple stones without blowing out the budget.
Some of the most striking pieces I’ve seen have been lab-grown pendants with pear-cut or marquise diamonds — shapes that can look astronomically priced when mined.
2. The sparkle is the real deal
Lab-grown diamonds don’t compromise on fire or brilliance. When they hit direct sunlight or the soft glow of indoor lighting, they deliver that same scintillation people love about mined stones.
3. You can match it to your personal values
A lot of shoppers tell me they feel proud wearing their lab-created diamond jewellery. Not in a showy way — more in the sense that they’ve made a thoughtful choice.
One reader wrote to me saying she wore her pendant as “a conversation starter for conscious luxury.” I like that phrasing. It captures the shift perfectly.
4. Pendants don’t rely on diamond rarity for value
Unlike investment-grade stones — which is a whole different rabbit hole — pendants are primarily about aesthetics and symbolism. You’re paying for design, craftsmanship, and the feeling the piece gives you.
That’s why lab-grown stones shine in this category: they allow you to elevate beauty without stressing about price jumps caused by supply limitations.
Where People Are Finding the Best Designs
I’ve noticed a quiet rise in bespoke and independent jewellers specialising in lab-grown stones, especially across Sydney and Melbourne.
Someone recently asked me where to start browsing, and I pointed them to man made diamonds pendants from Novita since the designs there lean modern and wearable, perfect for people who want elegance without heavy formality. Here’s the link I shared at the time:

One browse through collections like that usually gives shoppers a good sense of what’s trending — and whether they’re drawn to classic solitaires, halos, asymmetrical pieces, or ultra-modern designs.
A Surprising Trend: Heirloom-Inspired Styles
Even though lab-grown diamonds feel futuristic, I’ve noticed a growing demand for pendants inspired by old-world charm. Think Art Deco shapes, Victorian motifs, or the clean, geometric lines of mid-century jewellery.
It’s interesting because you’d expect the people drawn to man made diamonds to prefer modern looks — and many do — but a good portion actually lean nostalgic. Perhaps it’s a way of blending the sentiment of the past with the ethics of the present.
One jeweller told me people are asking for “their grandmother’s pendant recreated, but with a man made diamond.” That’s a beautiful sentiment — a continuation rather than a copy.
The Real Talk: Are Man Made Diamonds Less Special?
This is the question people whisper at jewellery counters when they think no one else can hear. So let’s talk about it openly.
No, they’re not less special.
If you attach meaning to a piece of jewellery — if it marks love, celebration, achievement, resilience — the origin of the stone doesn’t diminish that. Meaning comes from the wearer, not the mine.
There are people who prefer mined diamonds because they like the idea of geological rarity. And that’s totally valid. Jewellery is personal. But for most people, a diamond’s sparkle, size, colour, and symbolism matter more than its birthplace.
Interestingly, some people even feel that man made diamonds make their pieces more meaningful because they represent innovation and conscious choices. (One of the articles I read recently highlighted this shift beautifully; you can see a similar sentiment here: man made diamonds.)
How to Choose a Man Made Diamond Pendant
If you’re shopping for a pendant — whether as a gift or for yourself — here are a few tips I’ve learned along the way:
1. Think about neckline compatibility
Some pendants sit beautifully with V-necks, others with high collars or scooped tops. If you usually wear relaxed tees, something simple and centred works best. For dressier outfits, a more elongated drop pendant looks gorgeous.
2. Consider how often you’ll wear it
Daily wear pendants should be durable, simple to clean, and resistant to snagging. If you’re buying a “special occasions only” piece, you can afford more delicacy.
3. Check the chain quality
This is an underrated point but trust me — a flimsy chain has ruined many otherwise perfect gifts. A diamond pendant deserves a proper gold or platinum chain with sturdy links.
4. Understand the 4Cs, but don’t obsess
A perfectly cut stone will sparkle beautifully even if it’s not D-colour flawless. With pendants, especially, a well-balanced design matters more than microscopic inclusions.
5. Choose a design that feels like ‘you’
There’s no rulebook here. Some people love small, subtle diamonds. Others want a bold statement stone. Let your personality lead the way.
What the Future Looks Like
I’ve covered jewellery trends for more than a decade, and I don’t say this lightly: lab-grown diamonds are not a fad. They’re the future of accessible fine jewellery.
They won’t replace mined diamonds entirely — the traditional market has deep roots — but they’ve created a new lane. A more inclusive one. A more environmentally conscious one. And one that encourages creativity and experimentation.
Jewellers are already designing pieces specifically with man made diamonds in mind. They’re breaking free from old constraints, reimagining what luxury can look like.
And honestly? It’s exciting. It feels like the jewellery world is finally embracing a new chapter.
A Final Thought
If you’re considering a man made diamond pendant, don’t overthink it. Choose the piece that catches your breath a little. The one that will feel like you every time you glance in the mirror.
Jewellery isn’t meant to sit in a box. It’s meant to be worn, lived in, and loved. And whether your diamond was pulled from deep underground or grown in a state-of-the-art lab, its story becomes yours from the moment you put it on.
