Description

Above: Mystic topaz, faceted
Below: river-tumbled clear topaz, from the collection of John Passmore, Queensland.

'Mystic topaz' is clear, colourless topaz that has been faceted and before being coated with a thin film of titanium or similar substance, giving a brilliant rainbow effect. Though attractive looking, the layer is only a few microns thick and can be scratched or eroded away by harsh chemicals, thus the stone must be treated much more gently than regular topaz; which is harder than quartz.

I've seen entire trays full of faceted mystic topaz under bright show lights, they were downright blinding!

It's pretty stuff, but soooo fake-looking. Even the faceted CZ's next to them looked less fake, which is pretty amazing because CZ's are so bright and sparkly.

:lol:
