ASSOCIATED MINERALS: | Adularia, albite, amazonite, andesine, anorthite, azulicite, bytownite, labradorite, microcline, moonstone, oligoclase, orthoclase, paracelsian, sanidine and sunstone. |
ASTROLOGICAL SIGNS: | Aquarius. |
CHEMICAL STRUCTURE: | The general formula, for the common feldspars, is XAl(1-2) Si(3-2) O8 . The X in the formula can be sodium, Na and/or potassium, K and/or calcium, Ca. When the cation in the X position has a positive one (+1) charge such as with sodium or potassium, then the formula contains one aluminum and three silicons ions. If the formula contains the positive two (+2) cation calcium, then the formula will contain two aluminums and only two silicon ions. This substitution keeps the formula balanced, because aluminum has a charge of positive three (+3) and silicon has a charge of positive four (+4). Basically, the more calcium in the crystal, the more aluminum that will be needed to balance the charge. |
CLASS: | Silicates. |
CLEAVAGE: | Two directions of cleavage at nearly right angles |
CRYSTAL HABITS: | Tend to be blocky. Some feldspars may be triboluminescent. |

DENSITY: | 2.55 to 2.76. |
FIELD INDICATORS: | Twinning. |
GENERAL INFORMATION: | Tend to crystallize in igneous enviroments, but are also present in many metamorphic rocks. |
HARDNESS: | 6. |
LUSTER: | Dull to rarely vitreous. |
METAPHYSICAL: | Aides in detaching from the old and encouraging unconventional ways of attaining ones goals. It provides support in isues of self-love and awareness. It provides for connection with inter-galactic intelligence and helps in the communication with forces of this intelligence. |
