Amethyst Stone

The Amethyst is the gem stone for the Astrological sign Pisces which is a water sign, for the Wednesday Challenge anything to do with water. I have put these in a collage to show how the colour changes in different light. The top two are in the afternoon daylight on a window sill, the 3rd one is evening light in front of a large window. the last one is artificial light from a torch.
