The most common treatment for the enhancement of color is heat treating. In the heat treating process, rough un-cut rubies are heated to 1700-1800 degrees celsius, which improves both color and clarity. All rubies that SuperJeweler sells are heat treated for the enhancement of red color and clarity.
