Grown Brilliance is our first stop for distinctive lab-grown diamond jewelry. Brilliant Earth is the stronger choice if you want a broad selection of settings and the option to try them in a showroom. We recommend both and rate each 4.5/5, but neither is automatically the cheapest place to buy a loose diamond.
We have had good experiences with Grown Brilliance's finished jewelry, including an eternity ring and a heart necklace. Brilliant Earth's appeal is the combination of designs, diamond choice and a polished shopping experience. Start with the piece you want, then compare its full price.

Introduction to Grown Brilliance
Grown Brilliance specializes in lab-grown diamond jewelry. Its design-led approach was what first caught our attention, and it remains the main reason we recommend looking there.
We particularly like that the range goes beyond a few standard solitaire rings and studs. The eternity ring and heart necklace we bought supported our positive view of its craftsmanship. The packaging was also good, and our return experience was straightforward, with a quick refund.
That experience does not mean every piece is the best value. We are more cautious about its loose-diamond prices than we were when this comparison was first published.
Introduction to Brilliant Earth
Brilliant Earth began in 2005 and has built a broad jewelry business around sourcing, design and an online-plus-showroom shopping experience. It sells mined as well as lab-grown diamonds.
We like being able to research a stone online and then try settings in person. Brilliant Earth announced its 43rd US showroom, in San Antonio, in August 2026. Our assessment also draws on visits to its showrooms.
Both brands offer more than engagement rings. Earrings, pendants and other finished pieces can be the better reason to choose one over the other.
Grown Brilliance vs. Brilliant Earth: diamond selection
For loose diamonds, both gave us plenty of choice in the research. What matters more is whether you can find an appealing stone in your budget, inspect it properly and pair it with the setting you want.
Grown Brilliance diamond quality and inventory
Our 2024 search recorded about 259,000 loose lab-grown diamonds, with a narrower range of grades than Brilliant Earth. Our search covered D–G color, VS2–IF clarity and Ideal or Excellent cut labels.
D–G diamonds run from colorless to near-colorless. VS2–IF covers diamonds with small internal features through to internally flawless stones. You do not need the highest clarity grade to get a beautiful diamond; the cut and how it looks matter more than paying for a distinction you cannot see.
Our August 2026 review check still found a substantial selection, but a large inventory does not settle the question of value.
Brilliant Earth diamond quality and inventory
The Brilliant Earth search recorded around 400,000 lab-grown diamonds, including roughly 100,000 marked for quicker shipping. Its size, color, clarity and cut ranges were broader.
More choice is useful if you know how to narrow it down. It also means you should not assume every result is equally good. For a round diamond, start with a strong cut, inspect the video and read the grading report. For fancy shapes, proportions and appearance matter more than a seller's cut label alone.
Diamond selection summary
We would not choose between these jewelers on catalog size. Both had enough diamonds for a useful shortlist. Brilliant Earth offered the broader range, while Grown Brilliance kept more of its selection within higher advertised grades.
For finished jewelry, look beyond the headline carat weight. Ask about the smaller stones, metal, clasp or earring backs, and whether the piece is comfortable enough for the way you plan to wear it.
Grown Brilliance vs. Brilliant Earth: price comparison
Grown Brilliance diamond prices
Our near-one-carat Grown Brilliance examples cost $800–$1,170, below the Brilliant Earth range recorded in the same research. The listings did not have identical grades and proportions, so compare the individual reports as well as the prices.
One finished-jewelry example was a half-carat-total-weight solitaire pendant at $695. We also recorded $900 at Ritani and $950 at James Allen, but noted differences in cut quality. The lower price alone did not prove the pieces were equivalent.
That distinction matters with gifts. A pleasing design, a good chain and a well-cut stone can be worth more than a small saving on something you like less.
Brilliant Earth diamond prices
The Brilliant Earth reference range was $1,100–$1,890. We still think it is worth browsing for its settings and finished pieces, but we would not describe its loose-diamond prices as close to the strongest value sellers.
Our August 2026 review research recorded a 2.05-carat Grown Brilliance diamond at $1,615 and a 2.00-carat Brilliant Earth diamond at $2,100. Both were round, E color, VVS2 clarity and IGI graded, with top qualifying seller cut labels. They differed in weight and proportions.
For context, five 1.95-carat Ritani results with those color, clarity and lab criteria had a middle price of $422. This benchmark shows why we recommend comparing a value-focused seller before ordering.
Price summary
| Research example | Grown Brilliance | Brilliant Earth |
|---|---|---|
| Round diamond near one carat | $800–$1,170 | $1,100–$1,890 |
| August 2026 two-carat example | $1,615 at 2.05 carats | $2,100 at 2.00 carats |
Our two-carat price guide has current samples. If loose-diamond value is your main concern, include Ritani in the comparison. If the setting or finished design is the attraction, compare the total jewelry price instead.
Grown Brilliance vs. Brilliant Earth: shopping experience
The Grown Brilliance shopping experience
We enjoyed shopping at Grown Brilliance and were pleased with the jewelry we received. Its strengths are easiest to appreciate when you are choosing a complete piece, rather than comparing hundreds of loose stones.
Website and product images
The research found the site easy to navigate, with helpful images for judging a design. Close-ups are useful, but also look for a photograph that shows the piece on a person. Jewelry can appear much larger when it fills the screen.
Access to grading reports
Our main frustration was not always being able to open a diamond's grading report directly. That issue remained in the pages checked for our later review. Ask support for the report before buying a loose center stone if the listing does not provide it.
A grade summary is useful, but the full report gives you measurements and other details needed to compare diamonds properly.
Help choosing a piece
We found support helpful in our research. Use that help for specific questions: the report number, how a setting sits, or whether a custom change affects returns. A written answer is easier to refer back to than a general reassurance.
What stood out in our order
The craftsmanship, packaging and smooth return gave us reasons to recommend Grown Brilliance beyond its website. Our full review includes the purchase experience and photographs.
Its Truly Custom program now covers rings, necklaces, earrings and bracelets. That is different from choosing a diamond and standard setting in the ordinary ring builder, particularly for returns.
The Brilliant Earth shopping experience
Brilliant Earth's setting selection and diamond inspection tools made a strong impression. We liked having images, video and report information to work through before making a shortlist.
Showroom appointments add the chance to compare settings on your hand. If you are unsure about a band width or setting height, that can be more helpful than another hour of online browsing. Our research has included showroom visits to compare settings in person.
Shopping experience summary
Grown Brilliance is especially appealing when you already like one of its designs. Brilliant Earth is a good starting point when you want to compare many settings and would benefit from an appointment.
We would ask Grown Brilliance for any missing report before ordering. At Brilliant Earth, we would spend just as much time checking the price as admiring the setting.
Grown Brilliance vs. Brilliant Earth: sustainability
Grown Brilliance sustainability
Grown Brilliance focuses on lab-grown diamonds and says 96% of its gold is recycled. That is useful information about materials, but it does not establish the footprint of every finished piece.
Lab-grown diamonds avoid mining the diamond itself. They still take energy to produce, and the source of that energy matters.
Brilliant Earth sustainability
Brilliant Earth publishes more detailed sourcing information, including renewable-energy and certified diamond collections. Those descriptions apply to particular programs, not automatically to every diamond it sells.
Its mission report is a useful place to understand the differences. Renewable power and a certification that includes offsets should not be treated as the same claim.
Sustainability summary
We prefer specific product information to sweeping promises. If this is a priority, ask which program covers the exact diamond and what it says about production, metal and traceability.
For a meaningful environmental comparison, look at the materials and production information for the particular piece you want.
Grown Brilliance vs. Brilliant Earth: shipping and returns
Grown Brilliance advertises free US UPS 2nd Day Air shipping. Its ordinary return window is 30 days from shipment. Eligible standard designs and Design Your Ring purchases can receive a refund.
Truly Custom, special-order and High Jewelry pieces have store-credit-only terms. Its custom FAQ and general return page describe the start of the return window differently, so confirm the deadline before committing to a bespoke order.
Brilliant Earth's eligible return window is 30 days from availability for shipment or pickup, with exclusions for custom and altered items. Read its return terms before personalizing a piece. A delivery estimate also needs to allow for production, not just the courier's transit time.

Our verdict: Grown Brilliance vs. Brilliant Earth
We still recommend both. Grown Brilliance has the edge for a distinctive finished piece; Brilliant Earth has the edge for comparing settings with showroom help. The better purchase is the one whose design, diamond and total cost suit you.
For a straightforward loose-diamond purchase, compare prices elsewhere too. Neither a high review score nor an attractive showroom makes every listing good value.
