Lab-grown diamonds have seen a remarkable surge in popularity over the past decade. This shift is largely due to a growing societal focus on environmental consciousness and ethical consumption.

They have gained significant favor, especially among younger consumers who value sustainability and ethical sourcing. This shift is not just about ethics and the environment, though.

8 Best Places to Buy Lab Created Diamonds


1. James Allen

You might think we’re biased toward James Allen in several articles, but there’s a reason for that. Where else in the world (or on the internet, to be precise) can you find half a million diamonds, all showcased with 360-degree HD images, and up to 40x magnification? And the cherry on top? They’re offered at very competitive prices!

James Allen is one of the largest lab-created diamond retailers in the world. As of the time of writing this, they boast more than 54,000 lab-grown diamonds in their unique collection.

They offer thousands of superb diamonds around 1 carat, providing plenty of choice, but one 8.37 carat diamond caught our attention!

We doubt this has ever happened before: owning an 8+ carat diamond (yes, lab-created diamonds are REAL diamonds) for $33,000?

We know that $33k isn’t exactly cheap, but do you realize that the equivalent natural diamond would cost you more than $250,000? A quarter of a million dollars!

2. Brilliant Earth

Brilliant Earth is a trailblazer in the jewelry industry with a solid commitment to environmental sustainability. They offer a wide array of lab-grown diamonds, ensuring their customers have access to ethical and eco-friendly alternatives to mined diamonds.

Of course, Brilliant Earth caters to a range of budgets. With lab-created diamond prices starting from as modest as $300, they truly offer a spectrum of choices for every consumer.

3. Blue Nile

Blue Nile, akin to James Allen, stands as one of the leading online diamond retailers. For a long time, they held back from offering lab-created diamonds, but ultimately, they recognized and responded to market demands, and thus, began to offer lab-grown diamonds.

In an effort to cater to growing consumer demand for both affordable and ethically sourced options, Blue Nile has expanded their offerings to include high-quality lab-created diamonds. These options sit alongside their traditional collection, providing a comprehensive range that allows customers the flexibility to choose a diamond that aligns with their personal preferences, budget, and values.

Currently, they boast over 12,500 lab-created diamonds in their inventory. The range spans from a modest $300 to a staggering $153k for an 6-carat D color, IF diamond.

4. Lightbox Jewelry

Who would ever thought that the global diamond mining corporation, which once controlled more than 85% of diamond distribution over the world, will now start selling lab created diamonds?

That’s exactly the case with Lightbox Jewelry, it’s a company owned by De Beers which used to control the whole diamond industry, increasing & decreasing prices by controlling the mining operations and global inventory of diamonds!

This became impossible with the lab-grown diamonds, since companies can just “create” diamonds instead of mining them! So how De Beers will make money out of this? They joined the club under the Lightbox Jewelry company.

When you browse their site, you will not find thousands of diamonds, they just simply list 20 items (different cut grades, carats, shapes, colors), and you pick from them, as they have probably hundreds of each (think of it like shopping for a shirt! That’s basically the case with lab created diamonds).

What confirms this is their pricing:

At Lightbox, all our lab-grown diamonds are priced at 800 USD per carat, or 1500 USD for our Lightbox Finest™ collection.

Whiteflash, the esteemed home of the A CUT ABOVE® collection of super ideal Heart & Arrows diamonds, has made the strategic move into the realm of lab-created diamonds.

This wasn’t an expected move, as Whiteflash had previously been focusing solely on premium cut diamonds. However, the market’s rapid shift toward lab-grown diamonds is undeniable and Whiteflash decided to chart this course as well.

Staying true to their reputation for quality, they’ve chosen to offer only premium cut lab-created diamonds. These gems, carrying the certification of Hearts and Arrows Ideal Cut, showcase superior light performance, along with top scores in color and clarity (DEFG color, VVS1-VS1).

  5. Choose a reputable jeweler: It’s important to buy from a trusted jeweler who offers good customer service, clear information about their products, and has positive customer reviews.
  6. Consider sustainability: If you’re choosing a lab-grown diamond, chances are you care about sustainability. Look into the practices of the company you’re buying from to ensure they align with your values, even in natural diamonds, always seep Conflict-Free stones.
  7. Return policy: Check the retailer’s return policy. Reputable companies typically offer a 30-day return policy in case you’re not satisfied with your purchase.
