Lab-created diamonds have the same chemical and optical qualities of natural diamonds. Lab diamonds, also known as synthetic diamonds or artificial diamonds, are less expensive than natural diamonds, but have a lower resale value. Still, lab-created diamonds can be a beautiful alternative for an engagement ring.

Where you buy your lab-created diamond matters a great deal. It’s important to ensure that your diamond is indeed a lab diamond, not a diamond simulant like moissanite or cubic zirconia. Your lab-created diamond should have a certificate, ideally from the IGI. You also want to ensure that you get a competitive price for the diamond you choose.

Heading to a jewelry store or online vendor without doing your research can leave you with a less desirable diamond at too high of a price. Lab-created diamonds currently only make up 2-3% of all the world’s diamonds. So with lab-created diamonds especially, there are limited dealers who offer high-quality options.

That’s where our diamond expertise comes in. Over the years, we’ve vetted dozens of diamond vendors in-person and online to determine the most trustworthy sellers. Through our research and experience in the industry, we’ve found the very best diamond vendors that consistently outperform the competition of natural diamonds. Now we’re doing the same with lab-created diamonds. 

Our list of the best places to buy lab-created diamonds will help you select a stunning lab-created diamond that’s high-quality, offered at a competitive price, and sold through a vendor you can trust.

Tips for Buying Lab-Created Diamonds

To find the best lab-created diamond for your engagement ring or jewelry, follow our industry expert recommendations. 

1. Find a reputable vendor

Choosing a trustworthy retailer is a critical first step to ensuring you’re getting a high-quality diamond. Wondering where to buy lab-created diamonds? If you go with James Allen, Blue Nile, or Clean Origin, you won’t have to worry about the quality or price. You can shop with peace of mind knowing you’re getting a beautiful, reliable product. 

2. Narrow down your shape

Do you like the classic look of a round cut diamond or prefer a more unique shape like the pear? Decide on your favorite shape so you can hone in your shopping experience on diamonds that match your style. 

3. Look at cut quality

The quality that most greatly impacts a diamond’s beauty is cut quality. Look for a lab-created stone that’s either an Excellent or Ideal cut for an engagement ring.

4. Check for certification

For lab-created diamonds, the most common so far and reliable lab entity is the IGI. The IGI provides a color and clarity grade for lab diamonds, ensuring what you’re getting. GIA has also started providing a full certificate on lab-created diamonds but there aren’t that many of them yet. Without a certificate, it’s impossible to know if your lab-created diamond is real or worth the price you’re paying.

5. Aim for colorless

colorless lab-created round diamond

Unless you’re selecting one of the beautiful lab-created colored diamonds from Blue Nile’s Lightbox collection, you’ll want to ensure your diamond appears colorless to the naked eye. That means reviewing the diamond before purchasing to ensure it looks white. Generally, you don’t need to aim at the highest color grades. A lab-created diamond in the F-H color range will give you a white-looking stone that would look fantastic in any type of setting.

6. Choose an eye-clean diamond 

No blemishes or inclusions should be visible when you look at the diamond with the naked eye. For lab-created diamonds, this usually means a clarity grade of VS1 or VS2. Paying for a higher clarity grade will still only get you an eye-clean diamond, so we suggest not over spending in this area.

7. Compare similar diamonds

While two diamonds can have the same grading, they can still differ in how they appear. Narrow down your top selections to a few lab-created diamonds and look at them closely to see which one offers the most brilliance, sparkle, and overall gives you the right “vibe.” After all, this is a diamond that you or your partner will be wearing for a lifetime. 

If you’d like assistance in choosing a diamond, reach out to one of our experts to give you an honest evaluation. 

8. Select your ring setting

Ring setting styles range from solitaire to halo to three-stone designs. Take a close look at a few different styles before settling on the one. Knowing your partner’s ring style can also help you narrow down your final choice.

9. Get a second opinion

If you’re stumbling over which diamond or ring to choose, ask family or friends to take a look. You can also message us and we’ll give you our honest assessment of the ring and diamond. 

10. Make the purchase

Once you’re confident with your diamond and setting, buy the ring from a reputable vendor who offers hassle-free returns. This allows you to see the ring in-person and ensure it’s what you want. If you’re not satisfied, you can exchange the ring for something else. But almost every reader who follows our process for buying a lab-created diamond is extremely satisfied with their purchase.

Lab-Created Diamond FAQs

Here are the most common questions we receive about lab-created diamonds and where to buy them.

Do lab-created diamonds get cloudy?

No, lab-created diamonds don’t get cloudy because they are real diamonds that have the same chemical and optical properties as natural diamonds. Lab diamonds, or synthetic diamonds, are durable stones that stand up to everyday wear and maintain their brilliance, fire, and beauty for a lifetime. As with any diamond, regular cleaning and care of your engagement ring help to preserve its beauty.

Are lab-grown diamonds GIA certified?

Lab-grown diamonds can be GIA certified, although there aren’t that many of them yet out there, making IGI certified diamonds easier to find without sacrificing anything on the certificate quality.

Do lab-grown diamonds last?

Yes, lab-grown diamonds will last as long as natural diamonds and maintain their brilliance, fire, and beauty over time. Lab diamonds, also known as synthetic diamonds, mirror the optical and chemical qualities of natural diamonds. Proper care of your diamond ring will help to maintain its beauty and quality.

Do lab-grown diamonds look different?

No, lab-grown diamonds look identical to natural diamonds because they share the same chemical and optical qualities. Lab-grown diamonds are beautiful stones that offer an alternative to natural diamonds and tend to be approximately 30% less expensive. It’s important to note that the resale value of lab-created diamonds is minimal, if any.
