Better than nothing and possible window but all these reflections ate transparency. Actually picture doesn't show anything but somehow tells it is top stone. Exceptionally clean, transparent and brilliant beautiful stone of the gorgeous glowing color!In actuality it is not Upper Fine, but Lower Fine Grade. GIA certificate is available upon request, but frankly I don't know why some may want it if a stone is emerald (or tanzanite). Any not only gemologist but experienced dealer needs just a brief look to say if a stone natural or synthetic or diffused. Synthetic resins/polymers are easily recognized.
