When a mineral has traces of specifically aligned fibrous inclusions of rutile within it, it can exhibit a special attribute known as asterism. When the mineral is cut and polished, especially into spheres or cabochons, and a light shone upon its surface it is possible to see a six-rayed or twelve-rayed star reflected back from the surface. The minerals most prone to asterism are rose quartz; ruby and sapphire.
Asterated minerals reflect the "king and queen" within us. They remind us of our connection to the Stars and to the Light that shines at the heart of each sentient being. Some say these stones are grounding: I feel that they are "badges" of honour, bestowed upon us by the Spiritual Hierarchy in recognition of (or as a reminder of) a specific task or tasks we have undertaken to perform for the expansion or awakening of the Light for All. In this way they are grounding only inasmuch as they strengthen our commitment and dedication as Lightworkers and help us focus more fully on our life-purpose. The nature of the mineral (see heading of each "mineral" section) will indicate the direction this focus might take.
