A new high tech enhancement process applied to colorless Topaz produces an interesting new variety called "Mystic Topaz” which displays a stunning rainbow effect. In order to convert colorless Topaz into Mystic Topaz, a high process know as thin film deposition is used. The cut and polished Topaz is coated with an extremely thin titanium film that bonds with Topaz at the molecular level. Very little heat is involved in the process. The treatment is durable, hard, and only a few microns in thickness. With care, the enhancement will last the life of the jewelry setting. Although Topaz is relatively hard (8 Mohs scale), it can be split with a single blow, a trait it shares with diamond. As a result it should be protected from hard knocks. To clean, one should use only a polishing cloth or mild detergent, combined with a gentle scrubbing with a soft toothbrush at the most. In order to avoid water stains on the coating, the crystal should be dried with a towel or soft cloth
