Should you choose a lab grown diamond or a natural diamond? It is a fair question, and the honest answer depends on what you actually value — not what a jeweller is trying to sell you. Both are real diamonds. Chemically, physically, and optically identical. Both can be certified. Both look spectacular on the hand. The difference lies in origin, price, and what those factors mean to you personally: natural diamonds form underground over billions of years, while lab grown diamonds are created in a controlled laboratory in a matter of weeks.
Natural diamonds in this article are graded by GIA; lab-grown diamonds by IGI. Market pricing data referenced below draws on the Rapaport Diamond Price Index and EDAHN Global market analytics.
Lab Grown vs Natural Diamonds at a Glance
The table below compares the two on the dimensions GCC buyers ask about most. Both are genuine diamonds; the right choice depends on your budget and whether long-term value or size matters more to you.
| Dimension | Natural diamond | Lab grown diamond |
|---|---|---|
| Origin | Formed in the earth over billions of years, then mined | Grown in a controlled lab in a few weeks using the same crystallisation process |
| Appearance | Identical to the eye | Identical to the eye — same fire, brilliance and sparkle |
| Certification | GIA certificate (independent lab) | IGI certificate (independent lab) |
| Price | Higher — the premium reflects rarity | Typically 60–85% less for a comparable stone |
| Resale value | Stronger long-term value; traditional heirloom choice | Priced for beauty and value today rather than resale |
| Best for | Heirlooms, tradition, long-term worth | A bigger or higher-grade stone on the same budget |
What Lab Grown Diamonds Actually Are
A lab grown diamond is not a simulant. It is not cubic zirconia, moissanite, or glass. It is a real diamond grown in a controlled environment that replicates the extreme heat and pressure conditions found deep within the earth. The result is a crystal with the exact same carbon structure as a mined stone — the same hardness (10 on the Mohs scale), the same refractive index, the same thermal conductivity.
No gemologist can reliably distinguish a lab grown diamond from a natural diamond with the naked eye, with a loupe, or even with standard trade equipment. Specialised machinery is required for identification. The stones are, to all practical intents and purposes, identical in how they look and how they wear.
Lab grown diamonds are produced using one of two processes — High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD) — and are graded using the same 4Cs as natural diamonds. IGI certified lab grown diamonds carry independent grading reports covering cut, colour, clarity, and carat weight, just as GIA certified natural stones do.
What Natural Diamonds Offer That Lab Grown Cannot
Natural diamonds formed over billions of years under geological conditions we cannot replicate. Each stone is unique in its growth patterns, inclusions, and light behaviour — no two are identical. That geological history is not just marketing language. For many buyers, the origin of the stone is genuinely part of what it means. The rarity is real, and for some people it matters — which is why natural diamonds remain a deliberate choice.
Natural diamonds also carry a more established secondary market. GIA certified natural diamonds — particularly D to F colour, VS or better clarity, in popular shapes — have historically held or appreciated in value over time, though they are not a liquid investment in the way financial assets are. If resale value matters to you, natural diamonds have a stronger case — and it is why they remain the traditional choice for heirloom pieces meant to be passed down.
The Price Difference — and What It Means in Practice
Lab grown diamonds are typically 60 to 85 percent less expensive than natural diamonds of equivalent cut, colour, and clarity. On a mid-range stone, that difference can easily be AED 15,000 to 30,000. That gap either stays in your pocket, goes into a more elaborate setting for your lab grown diamond ring, or buys a significantly larger or better-cut stone.
To put it concretely: a budget of AED 20,000 applied to a natural diamond might get you a well-cut 0.70ct G VS2 round brilliant. Applied to a lab grown diamond of the same quality grade, the same budget gets you something closer to 1.5 to 2 carats. The visual difference on the hand between those two options is substantial.
This is not to say lab grown is the right choice — it depends entirely on whether the size and quality gain matters more to you than the natural origin. But the trade-off is real and worth understanding clearly before you decide.
For broader market context: lab-grown diamond wholesale prices have fallen approximately 75% between 2020 and 2025 as production capacity expanded globally (source: EDAHN Global). By contrast, natural 1-carat D/VS1 stones on the Rapaport Price Index have held within a ±8% band over the same period. According to Bain & Company’s 2024 Global Diamond Report, natural rough production is projected to decline 1–2% annually through 2030 as mines deplete, while consumer demand in emerging markets continues to grow.
One note on pricing across the GCC: at VYKA, every price is all-in — the price you see is the price you pay, delivered. VAT and any customs duty are already included, so nothing extra is owed at customs or on delivery, whether you order in the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain or Oman.
Certification: GIA and IGI
Certification is what turns a stone into a documented asset, and every VYKA diamond ships with one. Natural diamonds carry a GIA certificate; lab grown diamonds carry an IGI certificate. Both the GIA and IGI are independent laboratories that grade a diamond's 4Cs — carat, cut, colour and clarity — and confirm its origin, so you are never relying on the seller's word alone.
Environmental and Ethical Considerations
Many buyers choose lab grown diamonds because of concerns about mining — land disruption, water use, and the historical human rights issues associated with certain mining regions. Lab grown production avoids open-pit mining entirely, which has an obvious appeal.
The honest counterpoint is that growing a diamond in a laboratory is energy-intensive. Facilities vary significantly in how much renewable energy they use, and the carbon footprint of a lab grown diamond is not negligible. The Kimberley Process has also significantly improved accountability in the natural diamond supply chain over the past two decades, though it is not without critics.
Neither option is without environmental trade-offs. Which matters more to you is a personal question and not one with a universally correct answer.
What Most Buyers in the UAE and GCC Actually Choose
The majority of VYKA engagement ring clients across the UAE and Gulf region choose lab grown diamonds — primarily because the budget difference allows them to achieve a significantly larger or better stone than would otherwise be possible. That is a practical decision, not an ideological one.
A smaller number of clients specifically request natural diamonds — some because of the origin and rarity, some because a partner has expressed a preference, and some because of long-term value considerations. Both are valid starting points and both lead to beautiful rings.
If you are still weighing it up, the decision usually reduces to two clear paths:
- Choose a natural diamond if: you value tradition, want the strongest long-term value, or are buying a piece to hand down.
- Choose a lab grown diamond if: you want a larger or higher-grade stone on the same budget, or prefer to avoid mining entirely.
Whichever you choose, our Ring Studio can set the stone into a bespoke design with a 3D preview in 24–48 hours.

Common Questions — Lab Grown vs Natural Diamonds
Are lab grown diamonds real diamonds?
Yes. According to the GIA, lab grown diamonds have the same physical, chemical and optical properties as natural diamonds. They are real diamonds grown in a controlled environment rather than mined — not simulants like cubic zirconia or moissanite — and to the naked eye they look identical.
Can anyone tell the difference between a lab grown and a natural diamond?
Not with the naked eye — and not with a jeweller's loupe or standard trade equipment either. Identification requires specialised gemmological machinery, which is why origin is documented on the certificate: GIA for natural diamonds, IGI for lab grown. In everyday wear, the two are indistinguishable.
How much cheaper are lab grown diamonds?
Lab grown diamonds typically cost 60 to 85 percent less than a comparable natural diamond of the same carat, cut, colour and clarity — a difference that can easily reach AED 15,000 to 30,000 on a mid-range stone. That lets you choose a larger or higher-quality stone for the same budget. At VYKA the price shown includes VAT and customs duty, delivered.
Do lab grown diamonds hold their value?
Natural diamonds are the stronger store of long-term value and are the traditional choice for heirloom pieces. Lab grown diamonds are priced primarily for beauty and value today rather than resale. Choose natural if long-term value matters most; choose lab grown if size and value now matter most.
Do lab grown diamond prices keep falling?
Yes, significantly over the past five years as production has scaled. This trend is likely to continue. It means lab grown diamonds are increasingly not treated as investment-grade assets, but it has no effect on the visual quality or durability of the stone you purchase today.
Which should I choose, lab grown or natural?
Choose a natural diamond for heirloom value, tradition and long-term worth. Choose a lab grown diamond for a larger or higher-grade stone within the same budget. Both are real diamonds and look identical, so the right choice depends on your priorities and budget.
Can I upgrade a lab grown diamond later?
Some jewellers offer upgrade programmes, though the terms vary. At VYKA, contact us to discuss options if this is a consideration.
Are VYKA diamonds certified?
Yes. Every natural diamond comes with a GIA certificate and every lab grown diamond with an IGI certificate, both from independent laboratories. Each order also includes fully insured, door-to-door delivery and a 30-day money-back guarantee on in-stock pieces.
