Legend has it that topaz dispels all enchantment and helps improve eyesight. In ancient times, it was believed that topaz had the power to increase strength and make the wearer invisible. Today, the gem is favored for its exquisite blue hue which can range from cool icy blues as featured in Le Vian®'s Ocean Blue TopazTMto the deep, Mediterranean blues in Deep Sea Blue TopazTM.
An interesting characteristic of topaz is its ability to build up a distinct electrical charge from heat or friction that it will retain for several hours. Blue is the most popular topaz color which is obtained through a diffusion treatment that is permanent.
