Brilliant Earth is a jewelry retailer that specializes in lab-grown diamonds and ethically sourced gemstones

Brilliant Earth sells engagement rings, wedding bands, and other jewelry pieces online and through showrooms. The company focuses on lab-grown diamonds — diamonds created in a laboratory rather than mined from the earth — and gemstones sourced according to their stated ethical standards. If you are shopping for jewelry and wondering what sets this retailer apart from traditional jewelers or other online options, the main differences come down to the type of diamond, the sourcing claims, and the price point.

Lab-grown diamonds are chemically identical to mined diamonds but cost less because they take weeks to months to produce rather than billions of years. Brilliant Earth's business model centers on this cost difference and on transparency about where stones come from. Whether that matters to you depends on what you prioritize in a purchase — price, environmental impact, or the traditional appeal of mined stones.

Key Takeaways

  • Brilliant Earth sells lab-grown diamonds, which cost 30 to 50 percent less than mined diamonds of comparable quality but are chemically identical.
  • The company publishes sourcing information for gemstones and metals, though lab-grown diamonds do not have a mining origin to disclose.
  • Prices vary widely depending on the diamond's carat weight, color, clarity, and cut — the same factors that determine price at any jeweler.
  • Brilliant Earth offers a return window, warranty coverage, and the ability to resize or modify pieces, similar to policies at traditional jewelry stores.
  • Shopping online means you cannot see or try on pieces in person before purchase, though the company offers virtual consultations and has physical showrooms in select cities.

How lab-grown diamonds differ from mined diamonds

Lab-grown diamonds and mined diamonds have the same chemical composition — both are carbon arranged in a crystal lattice. A gemologist cannot tell them apart by looking at the stone alone. The difference is origin: mined diamonds come from the earth, lab-grown diamonds are created in a controlled environment using either high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) methods.

The cost difference is substantial. A lab-grown diamond typically costs 30 to 50 percent less than a mined diamond of the same carat weight and quality grade. This is because production takes weeks to months rather than geological time. Brilliant Earth uses this price advantage as its main selling point — you can buy a larger stone or higher quality for the same budget as a smaller mined diamond elsewhere.

Resale value differs between the two. Mined diamonds hold resale value more consistently because the market for them is older and more established. Lab-grown diamonds are newer to the market, and resale prices are less predictable. If you plan to sell the piece later, this is worth considering.

What Brilliant Earth discloses about sourcing and ethics

Brilliant Earth publishes information about where gemstones and metals come from. For colored gemstones — sapphires, emeralds, rubies — the company states the country of origin and whether the stone is natural or lab-created. For metals like gold and platinum, they describe sourcing practices and certifications.

Lab-grown diamonds do not have a mining origin, so there is no supply chain to trace in the traditional sense. However, Brilliant Earth discloses which lab produces each diamond and provides documentation of the creation method. The company also publishes a sustainability report describing its environmental practices and sourcing standards.

Whether these disclosures matter depends on your priorities. Some buyers care deeply about avoiding conflict diamonds or supporting fair labor practices in mining. Others prioritize environmental impact and see lab-grown diamonds as a lower-impact choice because they require less land disruption. Still others view these claims skeptically or do not weight them heavily in their decision. All of these positions are reasonable — the information is available, and the choice is yours.

Pricing and what affects the cost of a piece

Brilliant Earth prices jewelry based on the same factors jewelers use everywhere: carat weight, color grade, clarity grade, and cut quality for diamonds; type and quality for gemstones; and the metal type and weight of the setting. A one-carat lab-grown diamond with excellent color and clarity costs more than a one-carat diamond with visible inclusions, just as it would at any jeweler.

Because lab-grown diamonds cost less to produce, Brilliant Earth's prices for comparable stones are generally lower than traditional jewelers' prices for mined diamonds. However, prices vary between retailers. Comparing a specific stone — same carat weight, color, clarity, and cut — across multiple jewelers (both online and in-store) will show you the range. Brilliant Earth is not automatically the cheapest option, but the lab-grown model typically offers better value than mined diamonds at the same quality level.

Custom pieces and special requests affect price. If you want a ring designed to your specifications, the cost depends on the complexity of the design, the materials used, and the labor involved. Brilliant Earth offers custom design services, and pricing is quoted individually.

Return policies, warranties, and modifications

Brilliant Earth offers a return window — typically 30 days from purchase — during which you can return unworn pieces for a refund or exchange. This is standard in the jewelry industry. The exact terms appear in their return policy, which you should read before ordering.

The company provides a warranty covering manufacturing defects for a set period (usually one year from purchase). This covers issues like loose stones or broken prongs, not damage from wear or misuse. Like any warranty, the details matter — read what is and is not covered before you buy.

Resizing, cleaning, and repairs are available. Brilliant Earth can resize rings and modify settings, though some changes may cost more than others depending on the complexity. Many traditional jewelers offer these services too, sometimes at lower cost if you have a local jeweler you trust.

Shopping online versus in-store

Brilliant Earth operates primarily as an online retailer, though the company has opened physical showrooms in select cities. Shopping online means you order based on photos and specifications rather than seeing the piece in person. This carries risk — the stone or setting may look different in person than on screen, or the size may feel wrong on your hand.

The company offers virtual consultations with jewelry specialists who can answer questions about specific pieces, help you choose between options, or discuss custom designs. This is not the same as trying on a ring in a store, but it does provide a chance to talk through your choices with someone who knows the products.

If you live near one of Brilliant Earth's showrooms, you can visit in person to see pieces and try them on before ordering. If you do not, the return window gives you a way to send back a piece that does not work for you, though this adds time and shipping costs to the process.

Alternatives to consider

If you are deciding between Brilliant Earth and other options, consider what matters most to you. Traditional jewelry stores let you see and try on pieces in person and often have established relationships with local craftspeople. They typically sell mined diamonds, which have a longer market history and more predictable resale value. Their prices are usually higher for the same quality.

Other online lab-grown diamond retailers include Lightbox (owned by De Beers), Vrai, and Ada Diamonds. Each has different pricing, design options, and sourcing practices. Comparing a few options side by side — same stone specifications, same setting style — will show you the price and service differences.

If you want a mined diamond but care about ethical sourcing, some traditional jewelers specialize in conflict-free or fair-trade diamonds. These typically cost more than lab-grown options but may align better with your values if you prefer mined stones.

Frequently Asked Questions

Will a lab-grown diamond look different from a mined diamond to someone looking at my ring?

No. A gemologist with specialized equipment can identify a lab-grown diamond, but the human eye cannot. Your friends and family will not be able to tell the difference by looking at the stone. The only way they would know is if you told them.

Do lab-grown diamonds hold their value?

Lab-grown diamonds typically do not hold resale value as well as mined diamonds because the market for them is newer and smaller. If you plan to sell the ring later, expect to recover less than you paid. If you plan to keep it, resale value is less relevant to your decision.

What if I order a ring online and it does not fit or look right?

Brilliant Earth's return policy allows you to send back unworn pieces within the return window for a refund or exchange. Shipping costs may explore depending on the reason for the return. Check the specific policy before you order so you know what is covered.

Can I get a lab-grown diamond certified by the Gemological Institute of America?

Yes. The GIA and other gemological labs certify lab-grown diamonds and note their origin in the certificate. Brilliant Earth provides GIA certification for many of their diamonds. A certified stone comes with documentation of its specifications, which is useful if you ever sell it or need to insure it.

Is buying a lab-grown diamond better for the environment than buying a mined diamond?

Lab-grown diamonds require less land disruption and do not involve mining operations, which can be environmentally damaging. However, they do require energy to produce in the laboratory. Whether one is "better" depends on how you weigh land use, energy consumption, and other factors. Both are lower-impact choices than some other consumer goods, and neither is impact-free.
