Top Consumer Reviews ranks Brilliant Earth best for lab-grown rings
Brilliant Earth’s 391,000-plus lab-grown diamonds, 11 shapes and 30-day free returns put customization front and center. The brand’s recycled metals and lifetime warranty add polish.
With 391,000-plus diamonds, 11 shapes, 30-day free returns and free resizing within 60 days, Brilliant Earth wins on the details lab-grown shoppers actually feel when a ring arrives on the finger. Top Consumer Reviews put those customer-friendly terms, plus free shipping, free diamond replacement for loose stones and a lifetime manufacturer warranty, at the center of its latest ranking.
That combination matters because the lab-grown market now rewards breadth as much as price. Brilliant Earth says it was founded in 2005 by Beth Gerstein and Eric Grossberg, after Gerstein began engagement-ring shopping and wanted a choice that matched her values. The company says that mission still runs through the business: its sustainability page says 99.5% of its gold and 96.4% of its silver are repurposed. On its lab-diamond pages, Brilliant Earth pushes two especially telling collections, the Carbon Capture Collection, which it says uses diamonds grown from carbon before it is released into the atmosphere, and the Renewable Collection, which it says is grown, cut and polished with 100% wind and solar energy.
The wider market helps explain why those claims resonate. A 2025 BriteCo report said more than 45% of U.S. engagement-ring purchases were lab-grown diamonds. It also found that the average lab-grown center stone grew from 1.31 carats in 2019 to 2.45 carats in 2025, while 85.9% of lab-grown diamonds sold that year were colorless, up from 37.7% in 2020. For shoppers comparing origin stories, that makes honesty about materials essential; Federal Trade Commission Jewelry Guides require sellers to describe diamonds and laboratory-created substitutes truthfully and to disclose material information.
Brilliant Earth’s own scale shows how far the category has moved beyond niche status. In full-year 2025 results filed March 5, 2026, the company said total orders rose 13% and that it booked the largest quarter of net sales in its history. A March 2025 filing described a vast virtual inventory of premium natural and lab-grown diamonds, while trade coverage put its showroom count at more than 40 in 2025, up from 37 in 2024 and 34 in 2022. The ranking reads less like a novelty list than a snapshot of a market where lab-grown sellers now compete on selection, design flexibility and the credibility of their sourcing claims.
