Colour stability is a vital factor influencing a gemstone’s desirability. IIGJ Lab offers specialized testing for Yellow and Pink-Orange Sapphire (Padparadscha) to determine if colour fades or shifts under normal light and environmental exposure.
Certain sapphires may exhibit colour instability or alterations when exposed to heat or intense light. Early detection is vital for identifying colour instability.
