First seen in 1998, the mystic topaz is definitely the most mysterious of the family! This natural stone is enhanced with different coating treatments to create its famous rainbow shimmer. “The process typically involves coating a natural, colourless topaz stone with titanium using a technique called chemical vapours disposition (CVD). The titanium coating is extremely thin and is usually applied to the stone’s pavilion. When the stone is tilted at certain angles, it shows off rainbow colours which change depending on the angle it’s viewed in.” Due to this, every mystic topaz varies in colour making each stone entirely unique.
Boasting a stunning orange-pink colour, the azotic topaz is a colour treated version of a naturally colourless topaz.
