Celebrities Who Wear Lab Grown Diamonds : A Sparkling New Trend

Red-carpet jewellery is changing. Celebrities are now wearing lab grown diamond earrings, necklaces, bracelets and rings at the Met Gala, the Oscars and film premieres.

These stones are not diamond lookalikes. According to the Gemological Institute of America, lab grown diamonds have essentially the same chemical composition, crystal structure and physical properties as natural diamonds. Their main difference is where and how they are formed.

Why Are Celebrities Wearing Lab Grown Diamonds?

Celebrity jewellery must look noticeable in photographs and videos. Lab grown diamonds give designers more freedom to work with larger carat weights, coloured stones and unusual settings at a lower price than comparable natural diamonds.

The trend is not limited to oversized red-carpet necklaces. Some celebrities have chosen small earrings, proving that lab grown diamonds can work for both statement styling and simple everyday looks.

Some buyers also prefer knowing more about how their jewellery was produced. However, the environmental impact of a lab grown diamond can differ between manufacturers because the source of energy used during production also matters.

Celebrities Who Have Worn Lab Grown Diamonds

Pamela Anderson

Pamela Anderson wore nearly 200 carats of white and pink lab grown diamonds by Pandora at the 2024 Met Gala. She returned to them at the 2025 Golden Globes with a 66-carat necklace, drop earrings and five tennis bracelets. The complete Golden Globes look contained close to 100 carats. 

Tyla

Tyla gave lab grown diamonds a less traditional look at the 2025 Met Gala. Her custom Pandora jewellery included a six-carat heart pendant and a diamond-set monocle, with the complete look reaching 30 carats. 

Odessa A’zion

At the 2026 Oscars, Odessa A’zion wore three lab grown diamond necklaces containing 148 stones and almost 55 carats in total. One necklace had previously been worn by Pamela Anderson, showing how a major red-carpet piece can be restyled. 

Meghan Markle

Meghan Markle brought attention to wearable lab grown diamond jewellery in 2019. During a visit to Smart Works in London, she wore Kimaï’s 18-karat gold Felicity earrings. Their curved design was modern without being oversized. 

Emma Watson

Emma Watson wore lab grown diamond earrings by Vrai & Oro to the 2018 Vanity Fair Oscars party. Made with recycled gold, they offered a quieter alternative to oversized red-carpet jewellery.

Lady Gaga

Lady Gaga chose statement cluster earrings for the London premiere of A Star Is Born in 2018. Designed by Anabela Chan, each earring combined freshwater pearls with nine round lab grown diamonds.

Penélope Cruz

Penélope Cruz has taken part in the category as both a wearer and a designer. She wore Atelier Swarovski earrings featuring 15.2 carats of lab grown diamonds at the Cannes Film Festival and also co-designed a fine jewellery collection using created stones.

Emma Watson, Lady Gaga and Penélope Cruz were among the early celebrities who helped move lab grown diamonds into major fashion events. 

Shilpa Shetty

In India, Shilpa Shetty has brought lab grown diamonds into the bridal jewellery conversation. As a brand ambassador and investor in Limelight Diamonds, she fronted its Navarambh bridal campaign in 2025. Her association reflects the category’s growing place in Indian occasion wear. 

Is Leonardo DiCaprio a Lab Grown Diamond Wearer?

Leonardo DiCaprio often appears in articles about celebrity support for lab grown diamonds because he invested in Diamond Foundry. However, investment and wearing the jewellery are not the same thing.

It is more accurate to describe him as an industry investor rather than a confirmed wearer.

How to Wear the Celebrity Lab Grown Diamond Trend

You do not need a 100-carat necklace to take inspiration from these looks. Diamond studs or curved earrings can give you the clean style seen on Meghan Markle and Emma Watson. Pearl-and-diamond clusters offer a softer version of Lady Gaga’s premiere look.

For weddings and parties, a tennis necklace or layered bracelet creates more visible diamond coverage. If you prefer something less common, consider a heart, marquise or coloured lab grown diamond similar to the custom pieces seen at the Met Gala.

What Should You Check Before Buying?

A celebrity name does not determine the quality of a diamond. Check the stone’s grading report, the 4Cs, gold purity, hallmarking and the brand’s return, exchange and buyback terms before making a purchase.

Choose according to your routine as well. A large necklace may look impressive on a red carpet, while secure studs, a pendant or a slim bracelet may receive much more wear.

Is This More Than a Passing Trend?

Lab grown diamonds have appeared at major public events from the 2018 Oscars season to the 2026 Oscars. These repeated appearances suggest that they are now an established jewellery category rather than a one-event experiment.

Celebrities have helped make the term familiar, but the decision still comes down to the buyer. Design, quality, certification, budget and personal preference matter more than who wore a similar piece.

Final Thoughts

Celebrity appearances have shown that lab grown diamond jewellery can be subtle, experimental, bridal or made for a major red carpet. The best approach is not to copy an entire celebrity look. Choose the part that suits you, whether that is a larger centre stone, an unusual shape or a design you can wear more often.
