What makes a green diamond green?
Green color in diamonds is caused by exposure to radiation. This natural phenomenon occurs when diamonds come in close contact with radioactive uranium from rocks near the earth’s surface. After exposure to radiation, diamonds are typically heat treated, which helps to disperse the color evenly throughout the stone.
