Lab Grown Diamonds

Diamonds grown in cultured laboratories are more pure, sustainable and meaningful far beyond those mined from the earth.

As lab grown diamonds are structurally and chemically the same as earth mined, geologists, jeweler or you cannot tell the difference with natural light, traditional tools, or even high magnifications. Specialising high end trace detectors and microscopes can identify a lab diamond, as it will be too uniform to have originated directly from the earth.
