Colour Varieties of Blue Topaz: 
Blue topaz comes in three main shades, produced through irradiation and heat treatment of colourless or pale topaz
Sky Blue --> Light, delicate baby blue
Swiss Blue --> Bright, vibrant medium blue
London Blue --> Deep, inky or steely blue (most valuable)
Treatment & Safety: 
Blue topaz is typically irradiated to produce its blue colour and then heat-treated to stabilize the hue.
The gem is safe for wear after the radiation has decayed to harmless levels (regulated internationally). 

Mystic Topaz is natural colourless topaz that has been enhanced with a thin coating of titanium or similar materials, producing a mesmerizing rainbow-like iridescence. It’s not a naturally occurring variety but a treated gem that’s popular for its striking visual effect.
Colour Effect:
The gemstone exhibits a play of colours across the surface due to thin-film interference, similar to how oil on water shimmers.
The effect can change depending on angle and lighting, giving it a "magical" or "mystic" appearance.

It is not recognized as a separate variety by gemological authorities but is widely accepted in commercial jewelry.
It is affordable and widely available, making it a favorite for statement pieces.
