Lab-Grown vs. Natural Diamonds: An Honest Comparison for 2026

It is the first question almost every couple asks us: "Should we go lab-grown or natural?" The
honest answer is that both are real diamonds, and the right choice depends on what you value
most. Here is a clear, no-pressure comparison from a jeweller that sells both.
Are Lab-Grown Diamonds Real Diamonds?

Yes. Lab-grown diamonds are 100% carbon crystal — chemically, physically and optically identical
to diamonds mined from the earth. They are graded by the same laboratories (IGI, GIA) using the
same 4C standards, and even trained gemologists cannot tell them apart without specialized
equipment. The only difference is where they were formed: deep in the earth over billions of years,
or in a laboratory over several weeks using the same conditions of heat and pressure.
The Price Difference Is Significant
This is where the two options diverge dramatically. A lab-grown diamond typically costs 50–70%
less than a natural diamond of the same size and quality. In practical terms, the budget that buys a
1-carat natural diamond can often buy a 2-carat lab-grown diamond of equal or better grade.
For couples who prioritize visual impact — a bigger, brighter stone — lab-grown offers unmatched
value. For couples who prioritize rarity and tradition, the premium on natural diamonds is the
price of owning something the earth made only once.
What About Resale and Long-Term Value?
Here we will be direct, because many retailers are not: no engagement diamond — natural or lab-
grown — should be thought of as a financial investment. Natural diamonds retain value better on
the secondary market, while lab-grown prices have declined as production has scaled. But an
engagement ring is not a stock portfolio. Its value is the life it represents. Buy the diamond that
makes sense for your budget and your story, not for a hypothetical resale.
Ethics and Sustainability
Lab-grown diamonds appeal to buyers who want certainty about origin — no mining, and a fully
traceable supply chain. That said, the natural diamond industry has transformed over the past two
decades: reputable jewellers source exclusively through the Kimberley Process, which certifies
diamonds as conflict-free. At TG Jewellers, every natural diamond we sell is certified and
responsibly sourced, and every lab-grown diamond comes with full grading documentation.
Side-by-Side: How to Decide
Choose a natural diamond if:
• Rarity and tradition matter deeply to you
• You see the ring as a generational heirloom
• You want the strongest long-term value retention
Choose a lab-grown diamond if:
• You want maximum size and quality for your budget
• Guaranteed origin transparency is a priority
• You would rather allocate savings to the wedding, honeymoon or a home
See Both, Side by Side, Before You Decide

Photos and online listings cannot show you how a diamond actually performs. The single best way
to decide is to view a natural and a lab-grown diamond of similar grade next to each other under
proper lighting. At TG Jewellers in Vancouver, we carry both and will show you the comparison
with zero pressure — because whichever you choose, it will be a real diamond.
Frequently Asked Questions
Do lab-grown diamonds test as real diamonds?
Yes. Lab-grown diamonds pass standard diamond testers because they are genuine diamond. Only
advanced laboratory equipment can identify their origin.
Do lab-grown diamonds get cloudy or fade over time?
No. This is a common myth. Lab-grown diamonds are just as hard (10 on the Mohs scale) and
durable as natural diamonds, and they never fade, cloud or degrade.
Can I put a lab-grown diamond in any setting?
Absolutely. Any engagement ring setting — solitaire, halo, pavé, three-stone — works identically
with natural or lab-grown diamonds. At TG Jewellers you can pair either type of diamond with any
setting in our collection.
