Collection: Lab-Grown Diamonds

A lab-grown diamond is a real diamond created in a controlled laboratory environment rather than formed naturally beneath the earth. Lab-grown diamonds have essentially the same chemical composition, crystal structure, and physical properties as natural diamonds and offer the brilliance and durability people expect from a diamond.

Yes. Lab-grown diamonds are real diamonds. They are not diamond simulants such as cubic zirconia. The primary difference between a lab-grown diamond and a natural diamond is their origin: natural diamonds form within the earth, while lab-grown diamonds are created using advanced technology in a controlled environment.

Lab-grown diamonds are generally created using one of two methods: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). Both methods recreate conditions that allow carbon atoms to form a diamond crystal. Once grown, the rough diamond can be cut, polished, and graded similarly to a natural diamond.

The main difference is how they originate. Natural diamonds form deep within the earth over extremely long geological periods, while lab-grown diamonds are created in a controlled environment over a much shorter period of time. Both are diamonds and can be evaluated for characteristics such as cut, color, clarity, and carat weight.

Yes. Lab-grown diamonds are extremely durable and, like natural diamonds, rate 10 on the Mohs scale of mineral hardness. This makes them well suited for frequently worn jewelry, including engagement rings, wedding jewelry, earrings, necklaces, and bracelets.

Lab-grown diamonds generally sell for less than comparable natural diamonds because their production process and supply are different from those of naturally formed diamonds. This can allow shoppers to consider a larger carat weight or different combinations of color, clarity, and design while staying within their budget.
