Natural Blue Spinel Trillion 6x6 mm Loose Gemstone S3810
Often mistaken for sapphire, this stone has superior clarity and sparkle. It is rarer in nature than sapphire. In fact, the gemstone has had a man-made version dominate the industry because the earth-mined stones are hard to come by. [the man-made stones are in very specific colors--think your class ring] Natural stones have many color variations.
