Review:

One of the most beautiful and most elegant gem in the world. People crazy about it and specially it use in jewelery. But on other end it use in astrology too.
Blue Sapphire was first synthesized in 1902. The process of creating synthetic sapphire is known as the Verneuil process. Only experts can distinguish between natural and synthetic sapphire. Colorless and pale blue sapphires from certain localities may be heat-treated to give them an intense blue color. Heat-treatment may also improve the clarity of some sapphires by removing tiny inner inclusions. Sapphire is pleochroic, displaying a lighter and more intense color when viewed at different angles. Some pleochroic sapphire is blue when viewed at one angle, and purple at a different angle.
