Lab-Grown Diamond Sales Are Skyrocketing. Here’s Why

Search for the term “lab grown diamond sales” online and you’ll find a growing number of reports pointing to one clear trend: lab grown diamonds are rapidly gaining market share. And the data supports it.

In 2020, the global lab grown diamond market was valued at $19.3 billion. By 2030, it is projected to reach $49.9 billion, reflecting a dramatic shift in how consumers buy diamond jewelry.

So why are lab created diamond sales rising so quickly? Why are more buyers choosing man made diamonds over mined diamonds?

This article breaks down the key reasons behind the surge in lab grown diamond sales—and what it means for today’s diamond buyers.

Why Are Lab-Grown Diamond Sales Increasing?

Lab grown diamond sales are increasing because lab diamonds are significantly more affordable, ethically produced, environmentally responsible, scientifically identical to mined diamonds, and widely accepted by both consumers and major diamond brands.

Below, we explore each factor in detail.

Lab-Grown Diamonds Are More Affordable Than Mined Diamonds

One of the strongest drivers behind the rise in lab grown diamond sales is price.

Lab diamonds are typically 40%–50% cheaper than mined diamonds of comparable quality. This price difference allows buyers to choose:

• Larger carat sizes

• Better clarity or color

• More elaborate engagement ring designs – all within the same budget.

For example, many buyers can purchase an engagement ring with a much larger lab grown diamond for the same price as a smaller mined diamond.

Why This Matters to Engagement Ring Buyers

Engagement ring shoppers are often younger and budget-conscious. For these buyers, lab made diamond rings offer a practical way to balance quality, size, and affordability without compromise.

Are lab grown diamonds cheaper than natural diamonds?

Yes. Lab grown diamonds generally cost 40%–50% less because they are produced in controlled environments without the high extraction and supply chain costs of mining.

Lab-Grown Diamonds Are an Ethical and Conscious Choice

Another major reason consumers are choosing lab grown diamonds is ethics.

Man made diamonds are created in laboratories, eliminating many of the concerns historically associated with diamond mining.

Ethical and Environmental Benefits of Lab Diamonds

• No links to conflict, war, or illegal mining

• No child labor concerns

• Reduced environmental impact

• No large-scale land disruption or excavation

Lab diamonds are produced in controlled environments, making them a more responsible option for buyers who value sustainability and transparency.

Lab grown diamonds are considered ethical because they are created without mining-related human rights or environmental issues.

Consumer Awareness of Lab-Grown Diamonds Is Growing Rapidly

A few years ago, many consumers were unfamiliar with lab diamonds. Today, that has changed.

Modern buyers actively research before purchasing diamonds. As a result, consumers now understand that lab grown diamonds are real diamonds, not simulants or imitations.

Why Awareness Has Increased

• Educational content from lab grown diamond brands

• Transparent grading and certification standards

• Easy online comparison of lab grown and mined diamonds

As awareness grows, so does confidence—directly contributing to higher lab grown diamond sales.

Major Diamond Brands Are Promoting Lab-Grown Diamonds

Industry adoption has played a critical role in accelerating lab created diamond sales.

According to recent reports:

• Approximately 7% of the global diamond jewelry market is now represented by man made diamonds

• This is up from about 3% in 2020

Many established diamond brands are actively expanding their lab grown collections, while some are reducing or stopping promotion of mined diamonds altogether.

Why Brand Adoption Matters

When major brands invest in lab grown diamonds, it:

• Signals long-term confidence in the category

• Builds mainstream consumer trust

• Accelerates market acceptance

This shift has helped move lab diamonds from a niche option to a mainstream choice.

Lab-Grown Diamonds Receive the Same Certification as Mined Diamonds

A key reason buyers now trust lab grown diamonds is certification.

• Cut and polished the same way as mined diamonds

• Evaluated using the same 4Cs (cut, color, clarity, carat)

• Graded and certified by recognized gemological laboratories

This identical treatment has removed much of the hesitation consumers once had and has further boosted lab grown diamond sales.
