About lab-grown diamonds

Lab-grown diamonds have a far less direct impact on the environment than mined diamonds. There are no physical differences between lab-grown diamonds and mined diamonds, the only difference is their origin. They share the same chemical and optical properties and are both 100% carbon-made.

Cultivated diamonds are created by scientists under the same conditions as those from the depths of the earth; pressure, heat & carbon. This is why lab-grown diamonds are real diamonds: just as real as any naturally mined diamond, showcasing the same mesmerizing fire, scintillation, and sparkle.
