Lighter if not much lighter than the real stone (obviously pointed light and white background along with extreme transparency), altered color (could not be otherwise: the stone has a magnificent Top Grade color), no inner glow of course. Not a real stone stones of such exclusive quality cannot be realistically shown on pictures but still not bad.
Clean, exceptionally transparent and brilliant gorgeous high-end stone of the magnificent Top Grade color! In actuality it is bottom Upper Fine if not in the middle of it. 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.
