Lab Grown vs Natural Diamonds
They are the same stone under the microscope. The difference is origin, price, and what you value.
Published · Updated
A lab grown diamond is a real diamond. It has the same carbon crystal structure, the same hardness, the same fire and brilliance as a diamond pulled from the earth. Under a loupe, a jeweller cannot tell them apart — the distinction is made only with specialised equipment, and it is a distinction of origin, not of quality.
What actually differs
| Lab Grown | Natural | |
|---|---|---|
| Composition | Crystallised carbon | Crystallised carbon |
| Formation | 2–4 weeks in a lab | 1–3 billion years |
| Certification | IGI / GIA graded | IGI / GIA graded |
| Price (same 4Cs) | 60–80% lower | Benchmark |
| Resale / buyback | Lower, improving | Established |
The headline is price. For the same carat, colour, clarity and cut, a lab grown diamond typically costs 60–80% less than a natural one. That gap is the entire reason the category exists — it lets you buy a visibly larger, cleaner stone for the same budget.
The 4Cs still decide everything
Whether lab grown or natural, a diamond is graded on the same four attributes. Do not let the origin debate distract you from them.
- Cut — the biggest driver of sparkle. Prioritise Excellent / Ideal cut above all else.
- Colour — graded D (colourless) to Z. For white gold, D–F looks icy; for yellow gold, G–H hides warmth and saves money.
- Clarity — VS1–VS2 is the sweet spot: eye-clean without paying for flawless.
- Carat — weight, not size. A well-cut stone faces up larger than its carat suggests.
Which should you choose?
Choose lab grown if you want the largest, cleanest stone for your budget and you see jewellery as adornment rather than an asset. Choose natural if legacy, rarity and long-term resale matter more to you than carat-per-rupee. Neither is 'better' — they answer different questions.
Buy the stone you will actually wear, certified, at a price you can see broken down line by line. Origin is a preference. Transparency is not.
Every Diava piece is made to order in your choice of lab grown or natural diamond, with a full price breakup before you commit.
Design your pieceCommon questions
- Are lab grown diamonds real diamonds?
- Yes. They are chemically, physically and optically identical to natural diamonds. Both are pure crystallised carbon and both are graded by the same laboratories such as IGI and GIA.
- Do lab grown diamonds pass a diamond tester?
- Yes. Because they are genuine diamonds, they test positive as diamond on a standard thermal tester. Distinguishing them from natural stones requires specialised laboratory equipment.
- Are lab grown diamonds cheaper?
- For the same carat, colour, clarity and cut, lab grown diamonds typically cost 60–80% less than natural diamonds.
