Lab Grown vs Natural Diamond Necklace: Key Differences, Benefits & Value
Luxury Diamond Jewellery Guide
Why Choose a Lab Grown Diamond Necklace Over a Natural Diamond Necklace?
Put them side by side. Nobody can tell them apart. So the real question is which one fits how you actually shop.
I get asked this more than almost any other question these days. Put a lab grown diamond necklace next to a natural diamond necklace, and nobody can tell them apart, not under normal light, not under a jeweller's loupe. The origin is the only thing that's different. So the question people actually need answered isn't "Is it real?" It's whether the piece fits how they actually shop and wear jewellery.
Below is the honest comparison between lab grown and natural stones, what "lab-created" actually means (people mix this up constantly), and some pointers on choosing between a pendant, a tennis necklace, or something bigger once you know which direction you're headed.
What's Actually Different Between Them
Nothing, chemically. A lab grown diamond necklace employs diamonds that possess similar carbon arrangements and have the same degree of hardness and sparkle as an earth-mined one. Both are equally rated on the 4Cs by laboratories following the same criteria. The only difference between the two is the period that they take to develop: billions of years underground in the case of earth-mined and a couple of weeks in a lab setting for a cultured one.
Price is where the gap actually matters. A lab grown diamond necklace will usually be considerably less expensive compared to the same kind of natural diamond necklace of similar size and quality since you will not have to pay for the process of mining and extracting these stones. For most people I talk to, this cost difference is what makes the difference.
Lab Created Diamond Necklace: Same Diamond, Different Origin
Quick clarification since this trips people up a lot: "lab created" and "lab grown" are the same thing, just different phrasing. A lab created diamond necklace isn't a simulant, and it's definitely not in the same category as cubic zirconia or moissanite; those are different materials made to look like diamonds. It's a diamond, full stop, grown by copying the conditions a diamond forms under naturally, just compressed into weeks instead of millennia.
At Layla Diamonds, every lab created diamond necklace we sell goes through the same grading process as a mined one before it ever gets set. Worth asking about wherever you shop, since not everyone holds a lab created diamond necklace to that same standard.

Choosing a Lab Grown Diamond Pendant
This is where most people start. A lab grown diamond pendant means one well-cut stone on a chain, nothing to overthink. Most jewellers will let you compare a lab grown diamond pendant side by side with a natural one before you decide. Because the price is lower, you can usually afford a bigger stone or a better cut than you'd get going natural on the same budget, and that's often the real difference people notice, not the size so much as how clean the cut looks.
A few reasons this tends to be the entry point:
- It's a single-stone piece, so there's less to decide on than with a full tennis necklace.
- The lower cost means going up a size or a grade feels realistic.
- It layers easily later once you add other pieces to the collection.
1 Carat Lab Grown Diamond Necklace: The Everyday Choice
A 1 carat lab grown diamond necklace tends to be the sweet spot for wearing daily. It's noticeable without being flashy and cheap enough relative to a similar natural diamond necklace that you're not stressed about wearing it to the office and then out to dinner the same day. A lot of first-time buyers land here specifically, and it's usually the piece that makes them feel like they upgraded, not compromised.
If you're deciding between sizes, this weight is worth trying on before going bigger. It reads as substantial to most people without dominating an outfit, which is exactly why it's become the default recommendation for anyone buying their first piece.
Layering with a Lab Grown Diamond Tennis Necklace
Once someone owns one piece, a lab grown diamond tennis necklace is usually the next thing they go for. A line of diamonds sitting along the collarbone layers nicely with a pendant, and because lab-grown pricing goes further, it stops being a special-occasion piece and becomes something you can just wear.
A few things worth checking before buying one:
- Setting: Prong settings throw more sparkle; bezel settings hold up better against daily wear.
- Length: It should sit close to the collarbone rather than hang loose against the chest.
- Clasp strength: This is a piece you'll rarely take off, so a weak clasp is a real risk.
- Certification: Ask for grading documentation regardless of whether the stones are natural or lab grown.
This kind of well-chosen piece will outlast the trend anyway, so a little more effort is warranted in making sure the setting and clasp are chosen properly.
Building a Lab Grown Diamonds Jewellery Collection
It becomes a chain reaction once people get into the habit of wearing jewellery: one starts off by wearing a pendant, then a tennis bracelet, and finally earrings. That's basically why lab grown diamonds jewellery has grown so fast as a category. It removes the price ceiling that normally caps how much natural diamond jewellery someone can reasonably build up over time. More retailers carry it now too, so putting a matching collection together is much easier than it was even a couple of years ago.
Common starting points, roughly in order:
- A lab grown diamond pendant or solitaire piece
- A 1 carat lab grown diamond necklace for daily wear
- A lab grown diamond tennis necklace for layering
- Matching earrings or a bracelet from the same jewellery line once the necklace side feels complete

The Questions Worth Answering Before You Buy
- A lab grown diamond necklace and a natural diamond necklace are chemically identical. Same carbon structure, same hardness, same 4C grading criteria; the origin is the only meaningful difference, and under normal conditions nobody can tell them apart.
- "Lab created" and "lab grown" mean exactly the same thing. A lab created diamond necklace is not a simulant, not cubic zirconia, not moissanite; it is diamond, full stop, and at Layla Diamonds it goes through the same grading process as a mined stone before it gets set.
- A lab grown diamond pendant is the natural entry point. One well-cut stone, less to decide than a tennis necklace, and the lower cost usually means a bigger stone or better cut than the same natural budget would allow.
- A 1 carat lab grown diamond necklace is the everyday sweet spot. Noticeable without being flashy, wearable from office to dinner, and the default recommendation for anyone buying their first piece of fine diamond jewellery.
- A lab grown diamond tennis necklace stops being a special-occasion piece. Check prong versus bezel setting, collarbone length, clasp strength, and grading certification before buying; a well-chosen piece will outlast the trend.
- Lab grown diamonds jewellery removes the price ceiling on building a collection. Pendant first, then daily necklace, then tennis necklace, then earrings or a bracelet; the sequence that was previously aspirational becomes achievable.
