Transmitting light with no distortion, transparent. Graded in the setting.A deposit of a thin layer has been applied to the topaz to produce the intense color effect. The process utilizes a very high temperature treatment, diffusion of ions into the topaz, plus in some cases neutron bombardment has been used to create the color center. Diffusion processes causes the added ions to become part of the crystal surface with no distinct boundary. Do not put a gem treated in this manner into an ultrasonic cleaner.
