Red-Carpet Becomes Green with Lab-Grown Diamonds

Throughout time, celebrities were the core carriers and ambassadors of the new social trends. They used to reflect them in fashion styles and demonstrate stepping on the red carpet. Just observing ceremonies and official events, one can easily tell what things or ideas will be on social and fashion focus in the near future.  For sure, you have already noticed that celebrities’ wearing for officials at the end of 2024 and beginning of 2025 predicts an impending trend for lab-grown diamonds in luxury fashion.

Lab-grown diamonds are chemically and physically identical to their mined counterparts, but they come without the environmental degradation or ethical concerns often associated with traditional mining. Their rising popularity isn’t limited to red carpets either—they’re becoming more common in bridal jewelry, high fashion, and even investment collections, especially among younger buyers looking for sustainable alternatives.

And this is a case when the trend for things reflects brightly a trend for social values. Considering the sustainability of lab-grown diamonds and the growing number of celebrities who strive to wear them, one can say figuratively that the red carpets across the world are set to be transformed into green ones.

The diamond industry has faced growing pressure over the past two decades to address concerns over conflict diamonds, also known as blood diamonds. Documentaries and global awareness campaigns have shifted consumer sentiment, leading to greater demand for transparency and ethics in sourcing. In this context, lab-grown diamonds offer an appealing solution—luxury without compromise.

It is remarkable that among famous people choosing ethical diamonds, Indian celebrities are leading the way. This country still preserves a strong appreciation of natural diamonds, and cultured gems are at the very first stage of popularity. Yet, considering green signs from the Indian red carpet, lab-grown diamonds are a rising 2025 trend in India.

Why India’s Red Carpet Choices Matter

In recent years, Indian fashion has garnered increased global attention. International designers are drawing inspiration from traditional Indian motifs, textiles, and craftsmanship. As India’s film and fashion industry grow more globally influential, celebrity choices from Mumbai to Delhi are making ripples at Paris Fashion Week and beyond. This cultural shift has positioned Indian celebrities as key tastemakers on the global stage.”

So let’s look at celebrities promoting this trend – who are they and what do they appreciate most about lab-grown diamonds?

Ethically crafted, timelessly stunning, and consciously chic, her choice is inspiring modern brides across India and beyond.

You may wonder why we focused on Indian celebrities in the fashion section. The answer becomes clear when you consider some of the latest iconic images from around the world. Both luxury fashion and youth style increasingly feature oriental elements. Why is this happening, and what is driving this trend in fashion?

This influence is also reflected in social media statistics. On Instagram alone, hashtags related to Indian fashion and jewelry receive millions of interactions monthly. Lab-grown diamond brands that collaborate with Indian influencers often report higher engagement rates compared to global averages, emphasizing the commercial potential of Indian-led campaigns.

There’s no magic to it—just business. Companies are leveraging market advantages and are oriented towards a bigger pull of consumers.

India indeed is currently valuable for its large consumer base. India, with approximately 1.4 billion residents, has now surpassed China to become the world's most populous nation. Additionally, its GDP is on the rise. Significantly, the large population of Indian consumers has increased spending power, with average monthly household consumption growing from $271 in 2012 to $705 in 2023.

As a result, India's luxury market is attracting global brands, driven by a rapidly expanding affluent population, rich cultural diversity, and evolving consumer preferences. Luxury brands are increasingly customizing their offerings, launching exclusive collections, and collaborating with local talent to better meet the needs of Indian consumers.

Apparently, these new offerings are being streamed globally and are setting fashion trends.

A Global Wave: Lab-Grown Diamonds Around the World

While India is undoubtedly leading, other countries are also experiencing a surge in demand for lab-grown diamonds. In the U.S., Gen Z and millennial consumers are driving sales of ethical jewelry. Europe is seeing growth in eco-conscious collections, while Middle Eastern designers are experimenting with integrating lab-grown gems into traditional ornate pieces. This shows a global convergence of sustainability and style.

Madestones, an international lab-grown diamond trader, is sure that growing oriental style will shape the way of wearing lab-grown diamonds in 2025.

India, renowned for its exceptional jewelry craftsmanship, is at the forefront of a revolution in the jewelry market by producing some of the finest lab-grown diamonds globally. With advanced technology and a commitment to responsible luxury, Indian brands are transforming the industry.

Indian laboratories and jewelers have adopted cutting-edge techniques to simulate the exact conditions under which natural diamonds form—often using the chemical vapor deposition (CVD) method. These advancements allow precise control over color, size, and clarity, helping Indian designers push creative boundaries while maintaining ethical standards.

So, what trends can we expect in 2025?  

Here are three main tendencies that align with Oriental traditions and can be seen worn by the celebrities mentioned above.

The popularity of yellow and fancy-colored diamonds is on the rise. Traditionally, jewelry has featured clear, uncolored gems, but we are now seeing a shift towards lab-grown diamonds in vibrant yellow or champagne hues, similar to the one worn by Bhumi Pednekar.

The comeback of vintage and Art Deco style. Retro designs with a bright appeal to discreet royal elegance, and bold geometric cuts. Jewelers are combining baguette cuts, halos, and platinum settings to create nostalgic beauty.

Stackable and Minimalist Everyday Diamonds. Minimalist fashion is here to stay in 2025. Thin bands, delicate necklaces, and minimalist studs for everyday wear featuring small diamonds and calibrated melee stones will be very popular this season.

What This Means for the Future of Ethical Fashion

Lab-grown diamonds are not just a fleeting fashion statement; they signify a profound evolution in how society interprets luxury, identity, and values. Once considered a niche alternative, they are now redefining what it means to be stylish and socially conscious. In the past, wealth was often associated with rare, mined jewels—symbols of exclusivity tied to tradition. Today, the emphasis is shifting toward innovation, transparency, and a reduced environmental footprint.

With an increasing number of celebrities endorsing lab-grown diamonds, their visibility on the global stage has surged. These figures—admired not only for their talent but also for their influence—are making sustainability aspirational. Their fashion choices amplify a broader message: it is possible to celebrate beauty and craftsmanship without compromising ethical integrity.

Moreover, advancements in production technology are making these gems more customizable, accessible, and appealing to a wider demographic. Consumers are no longer choosing between ethics and elegance—they’re demanding both. Younger generations, especially Gen Z and Millennials, are leading this change by prioritizing authenticity and values-alignment in their purchasing decisions.

As we move into 2025, this trend is poised to become the new norm. Designers are being challenged to think sustainably from the outset, while brands are reevaluating their supply chains to meet growing expectations for accountability and environmental stewardship.

The red carpet may still be red in color, but its symbolism is transforming. It now serves as a platform for advocacy as much as artistry. With each appearance, celebrities are not just showcasing fashion—they’re casting votes for a more responsible industry. In this light, the glamour of tomorrow will not be measured solely by sparkle, but by the values it reflects.
