GIVE TREATED GEMS SPECIAL CARE
Many colored gemstones are routinely treated to improve the appearance of color and clarity. These treatments can be negatively affected by heat, solvents, steam and ultrasonic cleaners.
Knowing whether your gem has been treated is the first step to knowing how to care for it. This is where a GIA report comes in – it contains important information about your gem and any detectable treatments it may have undergone.
