In years past, the best lab-grown diamonds may not have been your first choice when shopping for fine jewelry like an engagement ring or everyday pieces from earrings to necklaces and bracelets. But the diamond jewelry industry has vastly changed over the years. Lab-created diamonds are as coveted as natural diamonds mined from the earth, resulting in choices aplenty. In fact, when you start to research these sparkly creations, including the best places to buy lab-grown diamonds, you'll learn that lab diamonds are real diamonds made of pure carbon. A common mistake is misinterpreting lab diamonds for simulated diamonds, like cubic zirconia and moissanite, made of different chemical compositions, which they are not. Lab diamonds are chemically identical to natural diamonds, but as the name indicates, they’re created in a lab rather than through the earth’s resources. While this makes them less rare, they’re undoubtedly valuable and often more affordable than natural diamonds.

Variety is among the best joys when shopping for lab-grown diamonds, and yes, the four Cs: color, cut, clarity, and carat, still apply. You can choose from all the different diamond cuts, from rounds to oval and emerald, set in yellow gold, white gold, and rose gold. Similarly, when determining where to shop for a lab-grown diamond, especially one as the focal point of the best engagement rings, you’ll find all the ring settings you could ever wish for, including traditional, modern, and vintage-inspired designs. And since lab-grown diamonds are created in a controlled environment, flawlessness is much easier to achieve at a friendly price, as is a bigger stone. To the naked eye, it's virtually impossible to tell if a diamond is natural or lab-grown.

Environmentally speaking, there are pros and cons to each. Ultimately, it’s whatever you value most and how you weigh things—compare the energy and water usage required for your chosen lab-grown diamond and compare that to the power and labor necessary for mining. In the end, like the best vintage jewelry, a diamond piece already in existence is the most sustainable option, though plenty of consciously-made new designs are out there. Ahead, peruse an edit of them from seven of the best places to buy lab-grown diamonds.

Brilliant Earth is a company of many firsts in the lab-grown diamond realm, and sustainability is at the forefront of the business. The online jewelry destination was one of the first to offer lab-grown diamonds, beginning in 2012, and in 2021, it became one of the first authorized retailers to introduce the independently certified Sustainability Rated Diamond collection. Every diamond within this assortment comes with a certificate to provide assurance of origin, responsible production practices, ethical stewardship, and climate neutrality with each lab-grown diamond. By 2025, Brilliant Earth’s goal is for 50% of lab-grown diamonds to be certified to an environmental product standard.

Additionally, Brilliant Earth is third-party certified as a climate-neutral company (including the company’s footprint from both present and past emissions), partnering with Carbonfund.org to offset carbon emissions by contributing to tropical rainforest conservation in Brazil.

Whether you’re shopping for a custom engagement ring, loose stone, or modern piece of everyday fine jewelry, you can feel confident in Brilliant Earth’s ethically-focused lab-grown diamond designs, including fancy colored stones—another unique offering from the label.

In 2010 Dousset opened his namesake Los Angeles showroom carving out a name all his own through his contemporary and innovative fine jewelry designs. Then, on August 3, 2020, Oui by Jean Dousset—a collection of affordable fine jewelry luxuries and engagement rings, including ready-to-ship lab diamond jewelry—debuted.
