22 Transmutation Gemstone coloration Facilities
 
This database contains 22 Research Reactors performing Gemstone coloration distributed over 12 Member States.
Note that this view includes Reactors of the following status:
PLANNED, UNDER CONSTRUCTION, OPERATIONAL

Gemstones may be irradiated with neutrons to improve their properties (e.g., change to a more desirable colour induced by the interaction of neutrons) in order to increase their demand and monetary value. The most common neutron irradiation being performed at research reactors is for topaz, which turn its grey color blue.
