Exposure of a material to radiation that causes color change in diamonds is called?

• A. Kaps
• B. Kerf
• C. Irradiation
• D. Kimberley Process (KP)

Answer: (C)

Irradiation is the exposure of a material to ionizing radiation that changes its color. In diamonds, the incoming radiation creates defects in the crystal lattice called color centers. These defects alter how the diamond absorbs and transmits light, producing colors such as blue or green. Artificial irradiation is often followed by heat treatment to stabilize the final color, while natural radiation in the earth can also create similar effects in green diamonds. Other terms shown refer to different ideas (a woodworking cut, a certification process, or an unfamiliar term) and do not describe color changes caused by radiation.
