Lab-Created Diamond FAQ

Are lab-created diamonds the same as natural diamonds?

While lab-created diamonds exhibit the identical optical, physical, and chemical 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, typically offering more size for the same cost, while 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 crystal - then expose it to high temperatures and pressures with a carbon coating as it grows to help 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 or Lifetime Diamond Commitment on lab-created diamond merchandise?

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

Will I still receive an appraisal and/or a laboratory certificate?

Zales' 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. If your diamond is mounted into jewelry, it will also be accompanied by an insurance appraisal.

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 Zales' lab-created diamonds are inscribed with “lab grown diamond” on the girdle.

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

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