DaVinci Does it Again!

Well, it appears that someone have invented a new type of stone.  Actually a new cut of stone.  You may ask well, how many ways can you skin a cat?  Apparently, one more way has been found and it provides quit a light show.  As reported by Barbara Moss, Editor at Colored-Stone.com, at the California Institute of Technology, a stone cut was developed that makes the gem change color by changing the angle of view.  Called the DavinChi cut, it refracts light the same way a compact disc does, providing a rainbow of colors in some instances.  Gemstones used include Amethyst, Blue and White Topaz, Citrine, and even diamonds.  All these are presented at stcanyon.com.  Small rubies or emeralds are then set beneath the culet to create an explosion of light.  Look for them soon at a jeweler and Sterling Canyon soon.
