Green color enhanced diamond jewelry is so similar to diamond jewelry made with natural green diamonds that only a trained gemologist with laboratory equipment can tell them apart.
In both cases the green color was created exposure to irradiation. The radiation can occur in nature by exposure to radioactive uranium near the earth’s surface. Or it can take place in a laboratory via the irradiation process.
Green diamond jewelry made with either type of color irradiated diamonds is very safe to wear. Nobody, not even the people who make or sell green color enhanced diamond jewelry, would touch it otherwise.
