Lab Grown Diamonds

Lab created diamonds are the smarter choice

Natural, earth mined diamonds are not the only choice for diamond engagement rings and fine jewelry. Modern technology allows us to create diamonds with the same chemical properties in a lab so they are not just beautiful, but are also better for the environment, workers and you. Our lab diamonds—also known as grown or synthetic diamonds—are physically and optically identical to naturally mined diamonds.

Frequently Asked Questions About Lab Created Diamonds

What is a lab created diamond?

Lab grown diamonds are a chemical replica of naturally mined diamonds, however they are made in a lab. Lab made diamonds are environmentally superior because they are not mined like diamonds found in the earth’s crust. They are made with crystallized carbon in a lab to have identical compositions both physically and chemically, meaning they are in every way equal to a mined diamond beside origin.

Are laboratory grown diamonds real diamonds?

The optical, physical and chemical composition of both natural diamonds and lab diamonds are the same. The difference between a laboratory grown diamond and a mined diamond is that one is created in a lab and the other is naturally mined.
