Black star sapphire stone price and value, black star of India meaning.
Black star sapphire stone
A star sapphire is a type of sapphire that exhibits a star like phenomenon known as asterism, red stones are known as star rubies. Star sapphires contain intersecting needle like inclusions following the underlying crystal structure that causes the appearance of a six rayed star shaped pattern when viewed with a single overhead light source.
The inclusion is often the mineral rutile, a mineral composed primarily of titanium dioxide. The stones are cut as cabochon, typically with the center of the star near the top of the dome.
Occasionally, twelve rayed stars are found, typically because two different sets of inclusions are found within the same stone, such as a combination of fine needles of rutile with small platelets of hematite, the first results in a whitish star and the second results in a golden colored star.
During crystallization, the two types of inclusions become preferentially oriented in different directions within the crystal, thereby forming two six rayed stars that are superimposed upon each other to form a twelve rayed star.
Misshapen stars or 12 rayed stars may also form as a result of twinning. The inclusions can alternatively produce a cat’s eye effect if the face up direction of the cabochon’s dome is oriented perpendicular to the crystal’s c axis rather than parallel to it. If the dome is oriented in between these two directions, an off center star will be visible, offset away from the high point of the dome.
