2026 Lab Grown Diamond Store Reviews

Here you can see how Ritani and Kay Jewelers match up head-to-head in a battle for the Best Lab Grown Diamond Stores in 2026.

Winner

Ritani

  • Pricing from $110 to $1,573,504 per diamond
  • Selection includes 400,000+ diamonds
  • 10 diamond shapes

Ritani is a great option if you want a huge selection of lab grown diamonds at transparent prices. The site makes browsing easy with helpful filters and 360-degree videos, plus perks like free in-store previews and 30-day returns. However, customer reviews mention slow shipping and service delays, and with a 3-star shopper rating average across the board, it isn't quite as competitive as some of the other lab grown diamond jewelers in our review. Ritani earns a middle of the road rating from us as well.

Kay Jewelers

  • Pricing from $290 to $50,320 per diamond
  • Selection includes 32,000+ diamonds
  • 10 diamond shapes

Kay Jewelers is a well-known name in the jewelry industry, offering a wide selection of lab grown diamonds and engagement rings and backed by over 100 years in business. While the site is easy to navigate and offers helpful images to guide your purchase, its inventory is somewhat limited, and customer reviews paint a frustrating picture of poor service and refund issues. With mostly negative feedback on third-party review sites and a shopping experience that feels just average, Kay Jewelers may be convenient for in-person shopping but falls short of being a top choice for lab grown diamonds.

Diamonds might be a girl's best friend - and, honestly, guys aren't immune either - but the sticker shock is what keeps most people from pocketing those glittering stones. Say "diamond" and you can practically see the dollar signs piling up. The upside is that there are truly more affordable ways to get the real sparkle, and we're not talking about fakes or cubic zirconia lookalikes. Lab-grown diamonds, for example, are chemically identical to mined stones and often cost far less, which means you can choose a stunning piece without blowing your budget.

We're talking lab-grown diamonds that offer the same brilliance as stones pulled from the earth - just at a fraction of the price. In short, a lab-grown diamond is a real diamond. The Gemological Institute of America confirms that lab-grown and natural diamonds match in hardness, durability, and clarity, and both are certified as diamonds. Because they're created in controlled settings, you can count on consistent quality and a wide range of sizes and shapes.

Lab‑grown, or man‑made, diamonds are produced in controlled labs using methods like high pressure high temperature (HPHT) to grow crystals that mirror earth‑mined stones in both chemistry and physical properties. To the naked eye they're indistinguishable - the sparkle and structure are the same - and any subtle differences only show up under serious magnification. Reputable grading labs even assess them by the same 4Cs as natural diamonds, making side‑by‑side comparison straightforward for buyers.

Natural diamonds form over millions of years deep in the earth, where intense pressure leaves trace nitrogen in the crystal. Lab-grown stones recreate those conditions in a controlled chamber and finish in a matter of months. Because they don't require risky mining, they're generally safer to produce, cost less, and can be the more ethical - sometimes even carbon-neutral - option. On average, you're paying about 30-50% less for a lab-grown diamond with the same cut and quality, so it's easier to choose a larger, certified stone without overspending. Both lab-grown and natural diamonds are real diamonds with the same physical and chemical properties, so the choice often comes down to origin, budget, and personal values.

Whether you're shopping for an engagement ring, treating yourself to something sparkly, or hoping to start a future heirloom, the real priority is finding a trustworthy source for quality lab-grown diamonds. A reputable seller will be transparent about cut, color, clarity, and certification - so you know exactly what you're getting. Taking a little time to check reviews, compare options, and understand return policies can make the whole experience feel as special as the stone itself.

If you're not sure which lab-grown diamond jeweler or gemstone retailer is going to be your best bet, don't worry. We've put together a few factors to help you choose the best spot:

Lab Grown Diamond Store FAQ

What are lab-created diamonds?
Lab-created diamonds are gemstones that are grown in a laboratory instead of being mined from the earth. They have the same chemical, physical, and optical properties as natural diamonds.
Are lab-created diamonds real diamonds?
Yes! They have the same characteristics as natural diamonds and can only be distinguished from natural diamonds using specialized equipment. Your lucky recipient - or your friends at girls' night - will never know.
Are lab-created diamonds more ethical than natural diamonds?
Lab-created diamonds are usually considered more ethical than natural diamonds because they are not associated with environmental destruction or human rights abuses. However, the environmental impact of producing lab-created diamonds and the working conditions of lab workers may also be factors to consider.
Are lab-created diamonds more affordable than natural diamonds?
Yes, lab-created diamonds are typically less expensive than natural diamonds of the same quality and size. This is because the cost of producing lab-created diamonds is lower than mining natural diamonds.
Do lab-created diamonds have the same resale value as natural diamonds?
Unfortunately, no. These man-made gemstones have lower resale value than natural diamonds because they are not as rare. However, this may change as lab-created diamonds become more popular and widely accepted in the jewelry industry.
How are lab-created diamonds made?
Lab-created diamonds are made using two different methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). HPHT mimics the natural diamond formation process by subjecting a small diamond seed to high temperature and pressure. CVD uses a gas mixture to deposit carbon atoms onto a diamond seed, which eventually grows into a diamond.
Are lab-created diamonds as durable as natural diamonds?
100%. They have the same hardness, toughness, and resistance to scratching and chipping.
Can lab-created diamonds be used for engagement rings?
Absolutely! They are a popular and ethical alternative to natural diamonds and offer the same beauty and durability. It's a great way to get a stunning ring at a much lower price than you'd spend for jewelry with natural gemstones. And unless you tell her (or him), your intended will never know the difference.
