The feldspar group includes the microcline, orthoclase and plagioclase feldspars. They commonly occur as prismatic crystals in aggregate groups. some of these stones exhibit the characteristics of adularesecence (a certain type of white or bluish light seen in a gemstone as it is turned), such as moonstone or labradorescence a brilliant display of colours when held up to a light source) as in labradorite. Most members of the feldspar group are translucent to semi-opaque and colours can be grey, pink white yellow on in the case of amazonite an aqua blue.
The mineral feldspar provides you with feminine, moon and Goddess energy. It helps you in honouring yourself as a woman, honouring your sexuality and ability to create new life.

Feldspar increases your self-respect, self-esteem and self-awareness. Feldspar eases menstruation and urges you to participate in conscious contraception.
