Each piece in this collection features brilliant lab-created diamonds. All our lab‑created diamonds are independently certified, designating cut, colour, clarity and carat weight.
Lab-created diamonds are an exceptional mix of master craftsmanship and science. In fact, they are created of the same material as natural diamonds which were formed in the earth billions of years ago.

Peoples' lab-created diamonds exhibit the same optical, chemical, and physical properties as natural diamonds - the core differences are the time they took to form and their origin.
With over 100 years of experience, we know diamonds. We believe that diamonds are right for everyone, but everyone may have a different idea as to which diamond is right for them. At Peoples, our goal is to help our customers determine the best diamond to meet their needs, whether it's natural or lab-created.

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.
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.
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.
Neither is inherently higher quality, as both lab-created and natural diamonds are available in a range of colour, cut, clarity, and carat weights.
Yes, we provide warranties and service plans for both lab-created and natural diamonds.
Peoples 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.
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 Peoples lab-created diamonds 1/5 carat and larger are inscribed with "lab grown diamond" on the girdle.
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.
