Abstract
The authors examined samples of Volyn topazes treated by radiation and subsequent heat treatment. The research was conducted with the using of optical spectroscopy method. The research defined the different origin of the blue colour of natural and treated topazes. Optical absorption spectra could be used for precise (correct) diagnostics of natural and treated topazes in jewelry.
