We do not sell treated opal. Opal, white opal, crystal or water opal and black opal are rarely enhanced other than by cutting. When they are enhanced, they may be immersed in sugar and sulfuric acid which brings out the fire, and they may be permeated with colorless oil, wax, resin, plastic and/or hardeners which can improve the opal's durability. Fire opal (red or orange) is almost never enhanced.
