Green Lab-Grown Diamonds

The green color in lab-grown diamonds is produced by the presence of certain impurities, such as the element nitrogen, during the diamond growing process. The nitrogen atoms replace carbon atoms in the diamond crystal lattice and cause the absorption of light in the yellow and blue spectrum. This causes the diamond to appear green to the human eye.

The exact process of creating green lab-grown diamonds can vary depending on the method used by the laboratory, but typically involves manipulating the conditions of the growth process to incorporate specific impurities that will produce the green color. For example, our HPHT method can produce diamonds with a more intense green color.
