2025’s Coolest Trend? Celebrities with Lab Grown Diamonds

From award shows to proposals, celebrities with lab grown diamonds are setting 2025’s biggest sustainable style trend.

What do Emma Watson, Alia Bhatt, and Penélope Cruz have in common in 2025? They're ditching mined diamonds and making lab grown diamonds the new normal. And it’s not just about style—it’s about values.

According to Bain & Company, lab grown diamonds could make up 25–30% of global diamond sales by 2030. Why? They're chemically identical, cost 40–60% less, and don’t carry the guilt of environmental harm. If you care about sparkle and substance, you're in good company.

Let’s dive into why celebrities are making the switch—and why you might want to as well.

Fashion Meets Ethics: Why Celebs Prefer Lab Created Diamonds

 

Celebrities are turning to lab created diamonds because they want their glam to match their values. These stones offer the same sparkle and optical properties as natural diamonds—but without the ethical baggage of mining.

Lab-grown diamonds are graded using the same 4Cs as natural diamonds: carat, color, clarity, and cut, ensuring they meet the same high standards.

Here’s why they’re switching:

1. Eco-conscious image: Stars like Emma Watson and Bhumi Pednekar prefer lab diamonds because they’re made using recycled gold and leave a much smaller carbon footprint.

2. Chemically identical: Lab grown stones are created in controlled environments, using processes like chemical vapor deposition, meaning no environmental destruction.

3. No conflict sourcing: Lab diamonds skip the ethical issues tied to mined diamonds, especially in conflict regions.

4. Same beauty, better story: Celebs love that lab diamonds are real diamonds, graded by bodies like the Gemological Institute and virtually indistinguishable to the naked eye.

Is Lab Diamond Real? What the Science Says

They are made of pure carbon and have the same physical properties as natural diamonds, making lab grown diamonds real The only difference is how they’re formed.

Natural ones grow deep inside the Earth, while lab diamonds grow in controlled environments using advanced methods like chemical vapor deposition (CVD) or the HPHT process.

Certified by Experts: What the Gemological Institute Says

Still unsure? Here's what matters: the Gemological Institute of America (GIA) and other trusted labs certify lab diamonds just like mined ones. They grade them based on the mohs hardness scale, optical properties, and even diamond crystals—the same way they do for earth-mined gems.

So next time you see celebrities with a laboratory grown diamond, know this: the sparkle is just as real. The science? Even stronger. And yes—lab grown diamonds are chemically identical to mined diamonds.

Behind the Sparkle: How Lab Diamonds Are Made

The growth process of lab grown diamonds mimics how natural diamonds form, just under controlled lab conditions.

Chemical Vapor Deposition (CVD)

CVD is a process where a tiny diamond seed is placed inside a sealed chamber. Then, carbon-rich gas is added and heated. The gas turns into plasma using microwaves or UV light. This allows carbon atoms to slowly attach to the seed, growing a real diamond layer by layer.

• This method uses controlled environments, so no mining is needed.

• It produces optically identical diamonds—hard to tell from natural diamonds even with a microscope.

• It’s eco-friendly and doesn’t involve any conflict zones.

High Pressure High Temperature (HPHT)

HPHT copies the natural diamond forming process deep inside the Earth. Scientists apply extreme pressure and high temperature to carbon, just like what happens when natural diamonds form underground.

• This method helps make gem quality diamonds faster.

• The diamonds are just as hard and shiny.

• They are also certified as real by labs like the Gemological Institute.

Natural vs Lab Created: Can You Tell the Difference?

 

The Rise of Cultured Diamonds in Pop Culture

More and more celebrities with lab grown diamonds are making headlines. Why? Because these diamonds are real, beautiful, and kind to the planet.

Cultured diamonds—also called lab grown diamonds—are created using science, not mining. But don’t worry, they are not fake or artificial diamonds. They are chemically identical to natural ones. Even experts say so.

Here’s why stars are switching:

• Lady Gaga stunned at the red carpet wearing a lab grown diamond necklace. She’s known for bold choices and this one sent a message: fashion can be ethical.

• These diamonds are grown in controlled environments using chemical vapor deposition or high pressure high temperature. Both mimic the same conditions deep inside the earth.

• Celebs love the excellent value—you get the same sparkle without the extra cost. At the London premiere of A Star is Born, she wore ethically-sourced cluster earrings featuring lab-grown diamonds, further emphasizing her commitment to sustainable fashion.

• They’re also a favorite in ethically sourced cluster earrings and custom yellow gold pieces.

Many people think mined diamonds are the only “real” ones. But science has changed that. Lab grown diamonds are real diamonds, just made differently. They even come with certificates from places like the Gemological Institute.

As pop culture shifts, so does how we think about beauty and value. Celebrities aren’t just wearing diamonds—they’re telling stories with them. And that story now includes cultured diamonds, freshwater pearls, and choices that matter.

Market Shifts: How Celebs Are Changing the Diamond Industry

Celebrities aren’t just setting trends—they’re reshaping the diamond industry. Their public shift toward lab grown diamonds is accelerating a market transformation that even major retailers can’t ignore.

Here’s how they’re driving real change:

• Demand is shifting: As A-listers flaunt lab diamonds on the red carpet, fans follow. This has led to a rise in market share for lab created diamonds, especially in engagement rings and statement pieces.

• Mined ones losing favor: Growing awareness of the environmental and ethical issues tied to mined diamonds has pushed celebrities to champion man made diamond alternatives—changing consumer perception.

• Education through fame: When stars like Leonardo DiCaprio (an investor in a lab diamond startup) speak up, it educates millions about options like cvd diamonds and the high pressure, high temperature processes used to produce diamonds sustainably.

• Old models under pressure: With more celebs choosing lab grown over natural diamonds, traditional diamond suppliers are facing increasing pressure to adapt or lose relevance.

In 2025, sustainability isn’t a side story—it’s becoming the main difference between staying current or getting left behind.

Celebrities with lab grown diamonds are leading a stylish, smart, and sustainable shift in 2025. These diamonds are real, beautiful, and better for the planet. With stars backing them and science proving their value, lab created diamonds are no longer the future—they're the now. Ready to make the switch?
