A '''star sapphire''' is a sapphire with an inclusion of [[asterism]], very small [[mineral]] deposits of [[rutile]] (titanium dioxide) that naturally form within the sapphire to create rays (up to six) that reflect light, a white appearance on an otherwise blue-colored [[gemstone]].
The Star of India, the largest known star sapphire in the world, weighs 563.35 [[carats]] (112.67 grams). It is almost flawless in appearance, and even has star rays on both sides of the gemstone.
