Origin Cambodia


White Topaz, a silicate mineral, is an unexpensive yet beautiful gemstone often used for jewellry. Colourless Topaz specimens undergo a radiation treatment to achieve one of the three colour hues used to describe the colour intensity of the blue Topaz: Sky Blue, Swiss Blue, London Blue.

Topaz has been known to mankind for at least 2000 years but it wasn't until past century that Topaz specimens were irradiated and blue Topaz became widely available on the gem market.

Our white Topaz comes from the Topaz mines in the deep south of Cambodia. This white Topaz has NO treatment and is absolute natural.
