• The color of a blue star sapphire is more important than its clarity. Sapphires are rarely completely clean and even very expensive stones can be slightly included. Subtle differences in color can make great variations in valuations of fine gemstones. Fine loose gemstones of good color and clarity are always rare and valuable. Highly saturated medium or medium dark blue tones are best, blue sapphires which are too dark or too light are worth considerably less. Star sapphire's fascinating asterism is just one reason for this gemstone's popularity. As with all sapphire, they are also very durable, having a hardness of 9 on the Mohs scale. Color is the single most important factor in determining the value of a sapphire. But in star sapphires it is a combination of the body color and the distinctness of the star. Display 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.
