Blue Sapphire’s grading includes color, clarity, cut, and carat weight. The best or the most desirable sapphires are those that exhibit a deep blue color with high saturation. Simplicity is also very important; adding less value adds more value. A cut changes the brilliance of the stone and, therefore, its value, and the carat weight demonstrates an exponential relationship with the value. To accurately Value Blue Sapphire, race also influences the prices since Kashmir, Burmese, and Ceylonese sapphires are highly demanded. Further, such treatments that include heat enhance have effects on value; the untreated stone has a better value as compared to the ones that have undergone treatment. Market price data is crucial, so consulting a professional gemologist is necessary.
