A fun and adventurous gem to wear that is affordable and is a great compliment to everybody. All Mystic Topaz begins as White Topaz, it then undergoes a process called vacuum deposition, this is a process where a titanium coating is permanently applied to the back of the gem through the use of electricity. The coating is difficult to scratch; however, as it is on the pavilion (bottom point) of the gem, it is protected by the setting.
