Lab-Grown Diamonds in Singapore: What Couples Need to Know
The Question Every Singapore Couple Is Asking
Lab-grown diamonds have gone from niche curiosity to mainstream option in the space of a few years, and Singapore couples are now asking about them in almost every consultation we have. The question is usually some version of: “Should we get a lab-grown diamond? Are they real?”
We’re going to give you the most honest answer we can — which means covering the actual differences, the trade-offs, and what we genuinely think matters when you’re making this decision.
What Is a Lab-Grown Diamond, Actually?
A lab-grown diamond is a real diamond. This is not a marketing claim — it’s chemistry. Lab-grown diamonds have the same carbon crystal structure, the same optical properties, and the same hardness (10 on the Mohs scale) as mined diamonds. A gemologist with a loupe cannot tell them apart by eye. Even sophisticated gemological equipment requires specific tests to distinguish them.
They are grown in one of two ways: High Pressure High Temperature (HPHT), which replicates the geological conditions under which natural diamonds form, or Chemical Vapour Deposition (CVD), which builds the crystal layer by layer from a carbon-rich gas. Both methods produce genuine diamond.
What lab-grown diamonds are not: cubic zirconia, moissanite, or any other diamond simulant. Those are chemically different materials. Lab-grown diamonds are compositionally identical to natural diamonds.
The Price Difference Is Significant — and Getting Bigger
This is where it gets interesting. Lab-grown diamonds currently cost roughly 70–85% less than natural diamonds of equivalent grade. A 1.5ct round brilliant, D colour, VS1 clarity in a natural stone might cost SGD 18,000–25,000. The lab-grown equivalent runs SGD 3,000–5,000.
That gap has widened dramatically over the past three years as production has scaled. And it is continuing to widen. Lab-grown diamond prices have dropped by 80–90% since 2016 and the trajectory shows no sign of reversing.
This has a practical implication: if you buy a lab-grown diamond today, its resale value in five to ten years will likely be very low — perhaps close to zero — because the cost of production will have fallen further, making your stone replaceable at minimal cost.
Natural diamonds have historically held their value better, though they are not an investment in any serious sense either. The resale market for second-hand diamonds is inefficient and you rarely recover what you paid.
So What Actually Matters?
The honest answer: it depends entirely on what you value.
If you want the largest, highest-quality stone your budget allows and you’re not concerned about long-term resale value, a lab-grown diamond makes strong practical sense. You can get a stone that would be completely out of reach in natural — 2ct, excellent cut, D colour, VVS clarity — for a fraction of the price.
If rarity and geological provenance matter to you — if part of what you value is that your stone formed over billions of years under extraordinary conditions — then that’s a real and legitimate preference, not a marketing myth. Natural diamonds are genuinely rare objects. Lab-grown diamonds are not.
If you’re concerned about ethical sourcing, the picture is more complicated than the marketing suggests. Lab-grown diamonds eliminate concerns about conflict diamonds, but their production is extremely energy-intensive and raises its own environmental questions depending on where the facility is powered from. Natural diamonds sourced from reputable suppliers with Kimberley Process certification are generally ethically sound.
What We Tell Our Clients
We work with both natural and lab-grown diamonds and have no commercial interest in steering you one way or the other. Here’s what we actually say in consultations:
If you’re working within a tight budget and you want the ring to look exceptional, lab-grown gives you options that simply aren’t available at the same spend in natural. A 2ct lab-grown in a beautiful bespoke setting, properly cut and set, will look extraordinary.
If budget is less of a constraint and you’re drawn to the idea of a stone with geological history — something that formed before humans existed — then natural makes sense and we’d encourage you to lean into that choice rather than second-guessing it.
What we push back on is the idea that one choice is objectively “better.” They’re different things with different trade-offs, and the right answer depends on your specific values and priorities.
Does It Matter for the Setting?
No — lab-grown diamonds can be set in exactly the same way as natural diamonds. Any setting that works for a natural stone works for a lab-grown stone of the same dimensions. The stone-setting process is identical because the material is identical.
One thing worth knowing: because lab-grown diamonds are cheaper, couples often choose a slightly larger stone than they would otherwise. This is sensible, but do make sure the setting is designed for the stone size you actually choose, not scaled up from a smaller reference design. We always design the setting around the specific stone.
Certification for Lab-Grown Diamonds
Lab-grown diamonds can and should be certified by an independent gemological laboratory. GIA (Gemological Institute of America) issues lab-grown diamond reports. IGI (International Gemological Institute) also certifies lab-grown stones and is widely used in the lab-grown market.
The grading process is the same as for natural diamonds — cut, colour, clarity, and carat weight. The certificate will note that the stone is laboratory-grown. When buying a lab-grown diamond, always insist on a GIA or IGI certificate. Do not buy uncertified lab-grown stones.
What About Telling People?
This comes up more than you’d expect. Some couples worry about family members asking, or about the stone “seaming less special” if people know it’s lab-grown.
Our view: the ring’s meaning comes from the relationship and the intention behind it, not from the geological origin of the stone. If you choose a lab-grown diamond, there’s nothing to be embarrassed about — it’s a chemically identical stone, often better cut and of higher clarity than you could afford in natural, set in a ring made specifically for your partner. That’s a meaningful object regardless of how the stone was grown.
That said, if you know your partner or your family will place significant weight on natural provenance, factor that into your decision. The stone’s meaning is partly constructed by the people around it.
The Bottom Line
Lab-grown diamonds are real diamonds. They cost significantly less than natural diamonds. They will likely continue to fall in price, which means their resale value will be low. Natural diamonds are rarer, carry geological provenance, and have historically held value better — but neither is a reliable investment.
Both are legitimate choices. The right one depends on what you value. We’re happy to talk through your specific situation without an agenda.
