The green color in a diamond is the result of exposure to radiation. The source of the radiation can be naturally occurring or performed in a laboratory. Natural radiation is the result of the diamond being exposed to radioactive uranium from rocks near the earth’s surface.
Are green diamonds radioactive?
Treated green diamonds can show residual radioactivity, generally due to immersion in radium salts. We report various activity measurements on two radioactive diamonds. The activity was characterized by alpha and gamma ray spectrometry, and the radon emanation was measured by alpha counting of a frozen source.
Do diamonds have radiation?
All diamonds have been exposed to natural radiation over the millennia before man unearthed them, so all colored diamonds have been “irradiated.” Irradiated diamonds are genuine diamonds that exhibit an intense color change such as blue, pink, green, etc., after being exposed to a strong radiation treatment.

Are green diamonds safe?
Are Irradiated Diamonds Safe? Because many green diamonds obtain their color from exposure to radiation in a laboratory (a process known as irradiation), there have been concerns about their safety when used in jewelry. The process of gemstone irradiation is very common.
What gems are radioactive?

Can jewelry radioactive?
According to Health Commissioner David Axelrod, the uranium glaze used in some of the brightly decorated cloisonne-type jewelry gives off low-level radiation if there is gold or beige in the color patterns. ”While short-term exposure to such jewelry would not pose a serious threat,” Dr.
Are green diamonds worth buying?
Unlike in colorless diamonds, even green diamonds below 1 carat are considered extremely rare and valuable. Fancy colored diamonds are valued based on their color, so it is common for these stones to be cut into shapes that help deepen the color.

Held within a diamond, such short-range radiation cannot escape, especially since we put a thin layer of non-radioactive diamond on the outside. Since diamond is the hardest substance known to humans, there is literally nothing we could use that could offer more protection.
