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.

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
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, a lab-created diamond in the F-H color range will give you a white-looking stone, like this G color diamond from James Allen.
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. This VS2 is an example of an eye-clean lab-created diamond.
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.
