It's the first real fork in the road for most people shopping for an engagement ring: lab-grown or natural? The marketing on both sides is loud, and most of it is designed to push you one way. Here is the honest version — what's actually the same, what's genuinely different, and how to decide without overthinking it.
The part nobody disputes: they're the same material
A lab-grown diamond is a real diamond. It is not a simulant, not cubic zirconia, not "fake." Chemically, it is pure crystallized carbon — atom for atom identical to a diamond pulled out of the earth. Optically and physically they are the same too: the same hardness (10 on the Mohs scale), the same refractive index, the same sparkle. A trained gemologist cannot tell them apart by eye; it takes specialized equipment to distinguish the two.
Both are graded on the exact same standard — the 4Cs — by the same independent laboratories. Every diamond we list, lab-grown or natural, comes with a GIA or IGI grading report, so the quality is verified the same way regardless of origin.
The one real difference: how they're made
The only meaningful difference between the two is origin — and time.
- Natural diamonds formed one to three billion years ago, deep in the earth, under extreme heat and pressure, then were carried toward the surface by ancient volcanic activity.
- Lab-grown diamonds are created in a matter of weeks in advanced facilities that reproduce those same conditions — either through High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD).
That's the whole story. Same crystal, different birthplace. Everything else — the price gap, the resale conversation, the "which is better" debate — flows from that single fact.
The price difference (and why it exists)
At an identical cut, color, clarity, and carat, a lab-grown diamond typically costs 60–80% less than a natural one. That is not a quality discount — the stones look and grade the same. It reflects supply: lab-grown diamonds can be produced to meet demand, while natural diamonds of a given grade are finite.
In practice, this is the single biggest lever you have over your budget. Choosing lab-grown often means a noticeably larger or higher-graded center stone for the same spend — or the same stone for far less, freeing up budget for the setting. If you'd like to see how that plays out across real grades and prices, our collection data page breaks it down.
What about resale and value?
Here's the honest answer most retailers avoid: diamonds of any origin are poor investments. Both natural and lab-grown stones sell at retail for far more than you'd recover reselling them — that's true of almost all jewelry. If "holding value" is your goal, a diamond isn't the vehicle.
Natural diamonds do retain a somewhat higher resale percentage today, largely because the lab-grown market is newer and prices have been falling. But for the overwhelming majority of buyers — people buying a ring to wear and keep, not to flip — this difference is academic. Buy the stone you love at a price that feels right, and plan to keep it.
So which should you choose?
Both are excellent. The right answer depends on what you value:
- Choose lab-grown if you want the most size and quality for your budget, or if the ethics of a created-not-mined stone matter to you. Explore our lab-grown diamonds.
- Choose natural if the billion-year origin story and traditional provenance are meaningful to you, and the premium is worth it for that. Explore our natural diamonds.
Whichever you choose, the thing that actually determines how a diamond looks is the same: cut. A brilliantly cut lab-grown diamond will outshine a poorly cut natural one every time. That's why we hold both to the same Triple Excellent standard — you can read exactly what we accept and reject before you buy.
Common questions
Will a jeweler be able to tell it's lab-grown?
Not by eye. Distinguishing lab-grown from natural requires specialized equipment, and lab-grown stones are laser-inscribed with their report number so the origin is always documented — never hidden.
Do lab-grown diamonds test as real diamonds?
Yes. Because they are real diamonds, they pass a standard diamond tester. Only advanced lab equipment can identify the growth origin.
Are lab-grown diamonds graded by the GIA?
Yes. The GIA and IGI both grade lab-grown diamonds on the same 4Cs scale used for natural stones, and the report travels with the diamond.
