Green diamonds are exceptionally unique in color and beauty. A pure Fancy Vivid Green diamond is one of the rarest hues among colored diamonds.
Natural irradiation is the cause for the unique green hue. The most common radioactive element that naturally occurs in the Earth’s crust involved in transforming a diamond green is Uranium. After extreme, extended exposure, diamonds absorb the alpha particles and deformation in the crystal lattice occurs, resulting in various hues of green.
There is a high level of difficulty involved in discerning between a rare natural irradiated diamond and a lab irradiated diamond. Diamond cutters leave what is known as a “natural” on the edge to prove the authenticity of the green hue.
