What Is a Lab-Grown Diamond?

What Is a Lab-Grown Diamond?

September 12, 2026· lorrinda khan

At Facet & Forge Jewelry, every engagement ring we design features a lab-grown diamond.

That choice is intentional.

Because we design for future-focused couples—those who are not only planning a proposal, but building a life together. A life that includes a home, a family, experiences, and long-term security alongside meaning and symbolism.

A lab-grown diamond supports that bigger picture.

At its core, a lab-grown diamond is a real diamond, created above ground. It is made of pure carbon, arranged in the same crystal structure as a mined diamond—giving it the same hardness, brilliance, and fire.

Different origin. Same material. Same beauty.

Are Lab-Grown Diamonds Real?

Yes—completely and unequivocally real.

In 2018, the Federal Trade Commission (FTC) clarified that a diamond is defined by its composition and crystal structure—not its origin. That means a lab-grown diamond meets the exact same definition as one formed within the earth.

Consumers should know where a diamond comes from—but origin does not change what it is.

A lab-grown diamond is:

  • Chemically identical
  • Physically identical
  • Optically identical

It is graded the same way, performs the same, and is designed to last a lifetime.

And that distinction matters.

Because while lab-grown and natural diamonds are both real, alternatives like:

  • White sapphires
  • Moissanite
  • Cubic zirconia

are not diamonds. They differ in composition, durability, and long-term performance.

Lab-grown diamonds are not substitutes.

They are diamonds—period.

Can You Tell the Difference?

No—not without specialized equipment.

To the naked eye:

  • Lab-grown and natural diamonds look identical
  • They sparkle the same
  • They wear the same

Even experienced gemologists rely on advanced tools to determine origin.

Lab-grown diamonds will also pass a standard diamond tester, because they share the same physical and chemical properties as natural diamonds—including thermal conductivity, which is what those tools measure.

In real life, there is no visible or functional difference.

How Lab-Grown Diamonds Are Created

Every lab-grown diamond begins as a microscopic carbon seed.

From there, advanced technology recreates the conditions that allow diamonds to form. There are two primary methods:

  • High Pressure High Temperature (HPHT)
  • Chemical Vapor Deposition (CVD)

In just a few weeks, carbon atoms form into a diamond crystal. That rough diamond is then cut, polished, graded, and set into a finished ring—just like any other diamond.

Different origin. Same result.

What’s the Same—and What’s Different

What’s the Same

Everything that influences how a diamond looks and performs:

  • Composition (pure carbon)
  • Hardness (10 on the Mohs scale)
  • Brilliance and fire
  • Color and clarity grading
  • Certification standards

What’s Different

Only three things:

  • Origin – created in a lab vs. formed within the earth
  • Rarity – natural diamonds are finite; lab-grown are not constrained by geology
  • Price – lab-grown diamonds are typically more accessible

And that difference in price creates meaningful flexibility.

A Shift in How Couples Choose

By 2023, more engagement rings in the United States began featuring lab-grown center stones than natural diamonds.

That shift reflects something deeper than a trend.

It reflects a change in how couples think:

  • More intentional
  • More informed
  • More focused on balancing meaning with practicality

When the diamond itself is the same, the decision becomes about alignment.

Why Facet & Forge Focuses on Lab-Grown Diamonds

We build our collection around lab-grown diamonds because they align with how modern, future-focused couples make decisions.

Ethical Clarity

Many couples today want confidence in sourcing.

Traditional diamond mining has long been associated with concerns such as:

  • Human rights abuses
  • Environmental impact
  • The historical financing of armed conflicts

Lab-grown diamonds provide a transparent alternative, removing that uncertainty from the process.

A Smarter Allocation of Investment

An engagement ring is meaningful—but it’s one part of a much larger financial picture.

Couples today are also planning for:

  • A home
  • A growing family
  • Transportation
  • Travel and shared experiences
  • Financial stability

Lab-grown diamonds often allow for:

  • A larger stone
  • Higher quality
  • More intentional design

Without overextending your budget.

It’s not about spending less.

It’s about spending in alignment with your priorities.

A Modern Perspective

Lab-grown diamonds represent a forward-looking mindset.

They reflect:

  • Innovation
  • Efficiency
  • Thoughtful decision-making

And importantly—they deliver the same beauty and durability required of a ring meant to last for decades.

Are Natural Diamonds Available?

At Facet & Forge, our engagement rings are intentionally designed with lab-grown diamonds.

However, for clients who specifically prefer a natural diamond, we do offer special-order sourcing.

We focus on lab-grown not because it is the only option—but because it is the option that best aligns with how the majority of our couples think today.

The Facet & Forge Perspective

This is not a question of real versus not real.

It’s a question of alignment.

Future-focused couples ask:

  • Does this reflect our values?
  • Does this decision support the life we’re building?
  • Does it balance meaning with responsibility?

A lab-grown diamond answers those questions with clarity.

In Summary

Lab-grown diamonds are real diamonds—identical in composition, beauty, and performance.

At Facet & Forge, we focus on them because they offer:

  • Transparent sourcing
  • Greater flexibility in value
  • A modern, intentional approach to buying

And most importantly:

They allow you to choose a ring that represents your relationship—without compromising everything else you’re building together.
