I wonder what may happen using some fiber optic cable to pump in some light to the gems... Years ago we had old lamps ect that had the fiber optic cable and changed colours of light as they rotated..
Haha, I actualy thought of that, but it is very hard to wrap the wire around the cable, It is the most impossible picture to take, because i could not shine the light dirrectly to the stone, looks 10x better with human eye
