Why More Couples Are Choosing Lab-Grown Diamonds in 2026

Lab-grown diamonds have gone from being an “alternative” stone to the most popular option for Gen Z and Millennials. Research by McKinsey has found that over half of younger couples are opting for lab-grown diamonds, taking the sustainable stone mainstream in 2026. 

This shift towards lab-grown diamonds isn’t just about the price tag. The priorities that couples have are changing with a greater focus on transparency and sustainability. With “conscious luxury” on the rise, it’s no surprise that couples are opting for lab-grown diamonds to create their dream engagement rings without compromising on their values.

At Valley Rose, we’re committed to transparency and sustainability with our lab-grown diamonds. Our gemstone finder allows you to choose your specific diamond, including from our range of carbon capture, SCS-007 rated, and melee lab diamonds. 

What is a Lab-Grown Diamond?

A lab-grown diamond is a diamond created in a controlled environment using advanced technology. It’s a common misconception that a lab-created diamond is a “fake” diamond, comparable to a cubic zirconia. In fact, a lab-grown diamond is chemically, visually, and physically ideal to mined or natural diamonds.

The only difference between lab-grown vs. mined diamonds is their origin and sourcing. Lab-grown diamonds offer better traceability with a lower carbon footprint.

Why Lab-Grown Diamonds Have Become So Popular in 2026

Lab-grown diamonds are leading a quiet revolution within the fine jewelry industry. While their popularity has been gaining momentum in recent years, 2026 is the first time they’ve become fully mainstream as the most popular gemstone alternative to mined diamonds. 

Below, we’re spotlighting 3 reasons why lab-grown diamonds are more popular than ever:

1.    Couples Want More Transparency

Younger couples are prioritising transparency in their decision-making. As consumers become more educated on the environmental impact of traditional mining practices, couples want to know exactly where their diamonds have come from. Lab-grown diamonds are a core part of ethical engagement rings as they support a more transparent supply chain.

2.   Sustainability Is Now Part of Luxury

Luxury is no longer just associated with brand names and logos. With younger consumers willing to pay more for eco-conscious products, we’re seeing longevity, ethical production, and sustainability become the new hallmarks of luxury.

While lab-grown diamonds are considered more sustainable, it’s important to note that their sustainability ratings will vary. It’s why we offer SCS-007 rated lab diamonds, the world’s first 100% climate neutral lab diamond, which offers an alternative to the excessive energy usage of traditional lab diamonds.

3.   Couples Can Prioritise Design

One of the most underappreciated perks of a lab-grown diamond is that they offer couples more flexibility with their design. The lower price tag of a lab-grown diamond means couples can choose from a wider variety of stone sizes, shapes, and settings.  

If you’re dreaming of a bespoke engagement ring, a lab-grown diamond will help you create a thoughtful design without compromising on your ethics – or the carat size!

Lab-Grown Diamonds are Redefining Luxury Engagement Rings

The best engagement ring is one that reflects your values and personal style. A lab-grown diamond is a more affordable and ethical alternative to traditional mined diamonds, giving you peace of mind with added transparency to make a more intentional choice when buying an engagement ring.
