The coating technology, known as thin film deposition, was pioneered by a company called Azotic Coating Inc. Mystic Quartz is a natural white quartz that has been coated giving it a beautiful rainbow colour effect. It is a not a natural but an enhanced gem. Since the treatment is a coating it is not permanently enhanced but while it lasts produces a kaleidoscope of colours. About Mystic Topaz - History and Introduction.Mystic topaz is quite a new gem type, first seen around 1998. Mystic topaz may be so-called because its attractive changing colors appear deep, mysterious and unusual. Mystic topaz usually appears to display rainbow colors, with greens, blues and purples being quite prominent. Since the treatment is a coating, it is not a permanent enhancement, but its remarkable appearance makes it an interesting gem in its own right.
