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.
