Star Sapphires are created when the corundum is intergrown with silky fibrous inclusions of Rutile. These combine with Sapphire’s trigonal structure to create six-rayed, and sometimes twelve-rayed star reflections when light is shined upon the stones. Therefore, Star Sapphires combine the vibrational properties of Sapphire and Rutile. This makes Star Sapphires the most energetically active of all Sapphires. All their effects are accelerated and amplified by the highly charged emanations of the Rutile threads.
