Lab-Created Diamonds at KAY:

As the largest diamond retailer, KAY is committed to giving you the best options for your diamond jewelry. Lab-created diamonds are growing in popularity, but a lot of people have questions about them. Are they the same as natural diamonds? How are they made? Find out more information below about lab-created diamonds so you can decide which option is right for you.

Are lab-created diamonds the same as natural diamonds? 

While lab-created diamonds exhibit the identical optical, chemical, and physical properties as natural diamonds, the core difference between them is their origin and the time they took to form.

Is a lab-created diamond better?

Both lab-created diamonds and natural diamonds vary in their diamond grading. Lab-created diamonds allow you to maximize your budget. They typically offer more size for the same cost. Natural diamonds are incredible works of nature and the traditional choice.

Where do lab-created diamonds come from?

Lab-created diamonds are created in a lab using advanced technology. Scientists start with a diamond seed - a small sliver of carbon crystals. It is exposed to temperatures and pressures. The carbon coating helps the diamond crystalize and grow to a larger rough diamond crystal.

Are lab-created diamonds or natural diamonds higher quality?

Neither is inherently higher quality, as both lab-created and natural diamonds are available in a range of color, cut, clarity, and carat weights.

Will I still receive my Lifetime Diamond and Color Gemstone Guarantee on lab-created diamond merchandise? 

Yes, we provide warranties and service plans for both lab-created and natural diamonds.

Will I still receive a laboratory certificate?

KAY lab-created diamonds are graded to the same standards as our natural diamonds. That means your lab-created diamond will be accompanied by an independent laboratory report detailing its "4 Cs" - cut, color, clarity, and carat weight. 

For more information on the "4 C's" of a diamond, view our "4 C's" guide.

Okay, so the untrained eye cannot tell the difference between lab-created diamonds and natural diamonds, what about the trained eye?

Because lab-created diamonds have the same optical, chemical and physical characteristics as natural diamonds, they cannot be distinguished even with a professional loupe under 10x magnification. That’s why KAY lab-created diamonds 1/5 carat and larger are laser-inscribed with “lab grown” or "lab created" on the girdle.  

Will a lab-created diamond maintain its value in the future?

A natural diamond has historically maintained its value. However, since lab-created diamonds are relatively new, it is unknown if they will retain their long-term value.
