One of the most pleochroic of all gem materials, this quality can go underappreciated in traditional heated stones. And even then, a gem that is orientated and cut correctly to showcase what is actually an instance of tri-chroism is exceptionally rare. One of those little gem oddities that we constantly look for and rarely find. This superb stone is one of the best we have seen - the strongly geometric cut allows entire facets to be taken over by green, light but pure blue and purple. As this mix and match you will see flashes of yellow and brown as well. It is akin to having the entire color range for the species present in one stone. Loupe clean and a fantastic size as well.
