A faceted, transparent dark green chrome-bearing Tourmaline with a remarkable colour-change effect. In daylight it is a very deep green colour, tending towards black, but in incandescent light it reverts to a bright raspberry red. 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 and at over 4 carats, a large sized gemstone of its type.
