Rock Bottom — Part 2: Who Is Still Attacking Laboratory-Grown Diamonds?

As laboratory-grown diamonds became more affordable and more popular, criticism of them intensified.

This was predictable.

Whenever a disruptive technology enters a market, the people most threatened by it tend to become its loudest critics.

The automobile threatened horse breeders.

Digital photography threatened film manufacturers.

Streaming threatened video rental stores.

And laboratory-grown diamonds threatened one of the most carefully protected luxury narratives in modern history.

To be fair, some criticisms of laboratory-grown diamonds are entirely reasonable.

Martin Rapaport has repeatedly argued that consumers should not expect laboratory-grown diamonds to retain their value over time.

He is probably right.

Laboratory-grown diamonds are not rare.

They can be produced in increasing quantities.

As production technology improves, prices naturally fall.

Consumers deserve transparency about that reality.

Likewise, executives such as Al Cook of De Beers have argued that rarity is fundamental to value.

This is also a reasonable position.

Natural diamonds are geological miracles. Formed billions of years ago under extraordinary conditions, their rarity is undeniable.

If rarity is what you value most, natural diamonds remain a compelling choice.

But something interesting happens when we look more closely at the conversation.

The loudest critics of laboratory-grown diamonds often share something in common.

They are deeply invested in natural diamonds.

Natural diamond miners.

Natural diamond traders.

Natural diamond marketing organizations.

Natural diamond inventory holders.

Natural diamond publications.

This does not mean they are wrong.

But it does mean they are not neutral.

No one should be surprised when people whose livelihoods depend upon the preservation of scarcity advocate for scarcity.

The more interesting question is why younger generations appear increasingly unconvinced.

Because when Gen Z and Millennials look at laboratory-grown diamonds, many of them do not see a threat.

They see freedom.

Freedom to purchase a larger diamond.

Freedom to allocate more money toward a home.

Freedom to travel.

Freedom to start a family.

Freedom to invest elsewhere.

Freedom from a luxury hierarchy they did not create and increasingly do not believe in.

And perhaps this is where the conversation becomes uncomfortable for parts of the jewellery industry.

Because laboratory-grown diamonds did not merely disrupt pricing.

They disrupted status.

For decades, the diamond industry relied upon a simple equation:

Bigger diamond = greater success.

Greater success = greater admiration.

Greater admiration = greater desirability.

But younger generations increasingly seem to reject this equation.

Not entirely.

Not universally.

But noticeably.

Many consumers no longer view luxury as something that should separate them from others.

They view luxury as something that should enrich their lives.

This distinction matters.

Because a person who purchases a natural diamond may be expressing an appreciation for rarity, geology, history, or craftsmanship.

Those are beautiful reasons.

But if the primary purpose of a purchase is to signal superiority, then laboratory-grown diamonds expose a difficult truth.

Perhaps the admiration was never about the diamond at all.

Perhaps it was about what the diamond allowed others to assume.

And when a visually identical alternative appears at a fraction of the price, the conversation suddenly shifts away from beauty and toward exclusivity.

That shift reveals something important.

The fiercest opposition to laboratory-grown diamonds is often not about what they are.

It is about what they remove.

They remove barriers.

They remove scarcity.

They remove the assumption that luxury must be inaccessible.

Most importantly, they remove the ability to easily distinguish who belongs inside the velvet rope and who does not.

That is not a diamond problem.

That is a human problem.

And one worth reflecting upon.
