Why did my diamond turn green?
Natural green colour is the result of radiation damaging the diamond. … It is this defect, or imperfection in the diamond lattice, that causes the absorption of predominantly red light, resulting in us perceiving green colour. Radiation damage can also occur when the diamond is deep in the Earth.
Why are my diamonds turning brown?
Brown diamonds are the most common color variety of natural diamonds. … There are several causes for the brown color, including irradiation treatment, nickel impurities and lattice defects associated with plastic deformation; the last is the predominant cause, especially in pure diamonds.

Can diamonds discolor?
Do Diamonds Change Color Over Time? As you can see, a diamond’s color is determined by its atomic structure. This structure is produced by a series of complex chemical reactions that happen deep within the earth. And since it’s impossible to change a diamond’s chemical makeup, it can’t change color over time.
How can you tell that a diamond is real?
Lay the stone onto the dot with the flat side down. Through the pointed end of the diamond, look down onto the paper. If you see a circular reflection inside the gemstone, the stone is fake. If you cannot see the dot or a reflection in the stone, then the diamond is real.
