Winner

James Allen

  • Pricing from $230 to $945,630 per diamond
  • Selection includes 55,813 diamonds
  • 11 diamond shapes

James Allen is a well-known online jeweler that offers a stress-free way to shop for engagement rings, loose lab grown diamonds, and fine jewelry. With over 55,000 lab grown diamonds, plus a 360-degree view of every item, it's easy to find the perfect gem. While the site had some temporary outages during our research, James Allen still stands out for its competitive pricing, free diamond upgrades, lifetime warranty, and highly-rated customer service.

Jared

  • Pricing from $230 to $21,070 per diamond
  • Selection includes 31,000+ diamonds
  • 10 diamond shapes

Jared is a well-known name in wedding jewelry, offering engagement rings and custom designs through its 200+ store locations and online shop. While it provides a decent selection of lab grown diamonds, its inventory is smaller than other retailers, and customer reviews suggest issues with pricing, warranty claims, and service quality. Jared's lower customer ratings and limited lab grown diamond options make it a less appealing choice for those looking for a unique or budget-friendly engagement ring too.

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.
