Brown Lab-Grown Diamonds

Brown color in lab-grown diamonds is caused by the presence of impurities, specifically nitrogen atoms, that are present in the diamond's crystal lattice. These impurities can be introduced during the diamond growth process, and the amount and distribution of nitrogen atoms in the lattice can affect the color of the diamond.

The more nitrogen atoms present, the more intense the brown color will be. The nitrogen atoms can be present as single atoms, grouped in pairs or in larger clusters, and this also affects the color of the diamond.
