** SOLD **

A faceted dark green chrome-bearing Tourmaline with a remarkable colour-change effect.

In daylight it is a very deep green colour, tending to almost black, but in incandescent light it reverts to a bright raspberry red (image 2).

The effect is unlike many colour-change gem varieties in that it only occurs when the light is shone onto the front of the stone, rather than transmitted through it (see image 3). 

A rare and unusual gemmological curiosity from a unique find in Mozambique which displays the unique Usambara effect.
