This gemstone is created through the process of titanium coating, which is generally applied only at the top of the stone, leaving the bottom part transparent. Here, titanium is used to coat the Topaz Stone, and as a result of this coating, mystic topaz gets its signature rainbow look. The titanium coating on mystic topaz is extremely durable – you can rest assured that the topaz stone will be resistant to chipping, scratches, and other damages. However, you do need to ensure that topaz stone is not exposed to UV light or high temperatures – this can cause the color of mystic topaz to fade.
