Product Code: TRCC22
Units in Stock: 1
A Tourmaline gemstone from Mozambique with a slight colour-shift effect.

In daylight and under household LED illumination it appears a dull olive-green colour, but when exposed to incandescent light it turns to a more mustard-green colour, as shown in image 2.

While this phenomenon can not be called a true "colour change" effect, it is still quite distinct.
