In today’s diamond market, the words we use matter more than ever. If you’ve been shopping for a diamond—especially online—you’ve probably come across the terms lab-grown and synthetic. They might seem interchangeable, but they carry very different weight in how we perceive value, quality, and authenticity.
Let’s unpack what these terms actually mean—and why it matters to you.
 

What’s the Difference?

Technically? Nothing.Both “synthetic” and “lab-grown” refer to diamonds made in a laboratory instead of being mined from the earth. They’re created using advanced technology that replicates the same conditions found deep underground.
The result? A diamond that’s chemically, physically, and optically identical to one that took billions of years to form in nature. Even experienced gemologists need specialized equipment to tell them apart.
So why the fuss over terminology?
 

The Power of Language

The term synthetic has been around longer. In gemology, it simply means “man-made”—not fake, not costume jewelry, not simulants. A synthetic ruby, sapphire, or diamond is still the real thing.
But in everyday conversation, “synthetic” tends to sound… well, fake. Think synthetic fabrics or synthetic flavors. That association can leave the wrong impression.
That’s why many in the industry, myself included, prefer lab-grown or laboratory-created. These terms are clearer and more consumer-friendly. They highlight the impressive technology behind these gems without diminishing their authenticity.
 

Why the Diamond Industry Cares So Much

Let’s be honest—this debate isn’t just academic. It’s about perception and market share.
Traditional diamond miners have spent decades building the narrative of the natural diamond: rare, romantic, formed over eons. And they’re right—it is an incredible story.
But the rise of lab-grown diamonds has challenged that narrative. They offer exceptional beauty, ethical sourcing, and often a better value. So, some in the mined diamond world have leaned hard into using the word “synthetic” to reinforce the idea that lab-grown diamonds are “less than.”
This language shapes how consumers view value, emotion, and prestige.
 

What the Regulators Say

Even the Federal Trade Commission (FTC) has weighed in. In 2018, the FTC ruled that “lab-grown,” “laboratory-created,” and “man-made” are all acceptable terms—as long as it’s clear the stone wasn’t mined. That’s a step in the right direction for transparency.
 

How Lab-Grown Diamonds Are Made

There are two main methods:
  • HPHT (High Pressure, High Temperature): Mimics the natural conditions inside the earth.
  • CVD (Chemical Vapor Deposition): Uses a carbon-rich gas to build up diamond crystal layer by layer.
Both methods produce diamonds that can be cut, polished, and set just like mined stones.
 

Ethics, Environment, and a Shift in Values

More and more clients I meet are asking about how their jewelry is sourced. They want to know their diamond didn’t fund conflict or harm the planet.
Lab-grown diamonds offer:
  • Peace of mind on sourcing
  • Lower environmental impact
  • Often a lower price point for the same sparkle
And let’s not forget: they’re just as real, just as beautiful, and just as worthy of becoming heirlooms.
 

What You Should Know as a Buyer

Don’t let the terminology trip you up. Whether the label says lab-grown or synthetic, here’s what matters:
  • It’s a real diamond, not an imitation
  • It’s certified and graded by the same labs (like GIA or IGI)
  • It offers incredible value and ethics
The only real difference? The story behind how it came to be—and the words used to describe it.
